Preamble The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This General Public License applies to most of the Free Software Foundation's software and to any other program whose authors commit to using it. (Some other Free Software Foundation software is covered by the GNU Library General Public License instead.) You can apply it to your programs, too. When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs; and that you know you can do these things. To protect your rights, we need to make restrictions that forbid anyone to deny you these rights or to ask you to surrender the rights. These restrictions translate to certain responsibilities for you if you distribute copies of the software, or if you modify it. For example, if you distribute copies of such a program, whether gratis or for a fee, you must give the recipients all the rights that you have. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights. We protect your rights with two steps: (1) copyright the software, and (2) offer you this license which gives you legal permission to copy, distribute and/or modify the software. Also, for each author's protection and ours, we want to make certain that everyone understands that there is no warranty for this free software. If the software is modified by someone else and passed on, we want its recipients to know that what they have is not the original, so that any problems introduced by others will not reflect on the original authors' reputations. Finally, any free program is threatened constantly by software patents. We wish to avoid the danger that redistributors of a free program will individually obtain patent licenses, in effect making the program proprietary. To prevent this, we have made it clear that any patent must be licensed for everyone's free use or not licensed at all. The precise terms and conditions for copying, distribution and modification follow. GNU GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 0. This License applies to any program or other work which contains a notice placed by the copyright holder saying it may be distributed under the terms of this General Public License. The "Program", below, refers to any such program or work, and a "work based on the Program" means either the Program or any derivative work under copyright law: that is to say, a work containing the Program or a portion of it, either verbatim or with modifications and/or translated into another language. (Hereinafter, translation is included without limitation in the term "modification".) Each licensee is addressed as "you". Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running the Program is not restricted, and the output from the Program is covered only if its contents constitute a work based on the Program (independent of having been made by running the Program). Whether that is true depends on what the Program does. 1. You may copy and distribute verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and give any other recipients of the Program a copy of this License along with the Program. You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee. 2. You may modify your copy or copies of the Program or any portion of it, thus forming a work based on the Program, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions: a) You must cause the modified files to carry prominent notices stating that you changed the files and the date of any change. b) You must cause any work that you distribute or publish, that in whole or in part contains or is derived from the Program or any part thereof, to be licensed as a whole at no charge to all third parties under the terms of this License. c) If the modified program normally reads commands interactively when run, you must cause it, when started running for such interactive use in the most ordinary way, to print or display an announcement including an appropriate copyright notice and a notice that there is no warranty (or else, saying that you provide a warranty) and that users may redistribute the program under these conditions, and telling the user how to view a copy of this License. (Exception: if the Program itself is interactive but does not normally print such an announcement, your work based on the Program is not required to print an announcement.) These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Program, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Program, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it. Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Program. In addition, mere aggregation of another work not based on the Program with the Program (or with a work based on the Program) on a volume of a storage or distribution medium does not bring the other work under the scope of this License. 3. You may copy and distribute the Program (or a work based on it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you also do one of the following: a) Accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, b) Accompany it with a written offer, valid for at least three years, to give any third party, for a charge no more than your cost of physically performing source distribution, a complete machine-readable copy of the corresponding source code, to be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, c) Accompany it with the information you received as to the offer to distribute corresponding source code. (This alternative is allowed only for noncommercial distribution and only if you received the program in object code or executable form with such an offer, in accord with Subsection b above.) The source code for a work means the preferred form of the work for making modifications to it. For an executable work, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the executable. However, as a special exception, the source code distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable. If distribution of executable or object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place counts as distribution of the source code, even though third parties are not compelled to copy the source along with the object code. 4. You may not copy, modify, sublicense, or distribute the Program except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense or distribute the Program is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance. 5. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Program or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Program (or any work based on the Program), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Program or works based on it. 6. Each time you redistribute the Program (or any work based on the Program), the recipient automatically receives a license from the original licensor to copy, distribute or modify the Program subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties to this License. 7. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Program at all. For example, if a patent license would not permit royalty-free redistribution of the Program by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Program. If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply and the section as a whole is intended to apply in other circumstances. It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system, which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice. This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License. 8. If the distribution and/or use of the Program is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Program under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License. 9. The Free Software Foundation may publish revised and/or new versions of the General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Program specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of this License, you may choose any version ever published by the Free Software Foundation. 10. If you wish to incorporate parts of the Program into other free programs whose distribution conditions are different, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally. NO WARRANTY 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. END OF TERMS AND CONDITIONS How to Apply These Terms to Your New Programs If you develop a new program, and you want it to be of the greatest possible use to the public, the best way to achieve this is to make it free software which everyone can redistribute and change under these terms. To do so, attach the following notices to the program. It is safest to attach them to the start of each source file to most effectively convey the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found. Copyright (C) This program is free software; you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation; either version 2 of the License, or (at your option) any later version. This program is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU General Public License for more details. You should have received a copy of the GNU General Public License along with this program; if not, write to the Free Software Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA Also add information on how to contact you by electronic and paper mail. If the program is interactive, make it output a short notice like this when it starts in an interactive mode: Gnomovision version 69, Copyright (C) year name of author Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. This is free software, and you are welcome to redistribute it under certain conditions; type `show c' for details. The hypothetical commands `show w' and `show c' should show the appropriate parts of the General Public License. Of course, the commands you use may be called something other than `show w' and `show c'; they could even be mouse-clicks or menu items--whatever suits your program. You should also get your employer (if you work as a programmer) or your school, if any, to sign a "copyright disclaimer" for the program, if necessary. Here is a sample; alter the names: Yoyodyne, Inc., hereby disclaims all copyright interest in the program `Gnomovision' (which makes passes at compilers) written by James Hacker. , 1 April 1989 Ty Coon, President of Vice This General Public License does not permit incorporating your program into proprietary programs. If your program is a subroutine library, you may consider it more useful to permit linking proprietary applications with the library. If this is what you want to do, use the GNU Library General Public License instead of this License. htmldoc-1.9.7/INSTALL.md000066400000000000000000000044211354715574200146300ustar00rootroot00000000000000How to Install HTMLDOC from Source ================================== To compile HTMLDOC you'll need C and C++ compilers (gcc is fine, most vendor compilers work, too). The JPEG, PNG, and ZLIB libraries are provided with HTMLDOC. For the GUI support you'll need FLTK 1.1.x or 1.3.x. FLTK is a LGPL'd cross- platform GUI toolkit and can be downloaded from: http://www.fltk.org/ For HTTPS support you'll need GNU TLS on Linux and UNIX. Windows ------- A Visual Studio solution is included in the "vcnet" directory. You must add the FLTK include and library directories separately for the solution to build. We highly recommend building and installing the HTMLDOC MSI target, as it takes care of registering the installation location with Windows. If you want to install the software by hand, create a directory for the software and copy the HTMLDOC executable, the "fonts" directory, the "data" directory, and the "doc" directory to it so that it looks like this: C:\Install\Dir\ htmldoc.exe data\ ... data files ... doc\ ... doc files ... fonts\ ... fonts files ... Then create the following registry entries with REGEDIT: HKEY_LOCAL_MACHINE\Software\HTMLDOC\doc = C:\install\dir\doc HKEY_LOCAL_MACHINE\Software\HTMLDOC\data = C:\install\dir Linux, macOS, and Other UNIX Platforms -------------------------------------- To compile the software under UNIX you first need to run the "configure" script in the source directory. Usually this is just: ./configure Then run "make" to build the software and generate the documentation: make Finally, run "make install" (typically as root) to install the software: sudo make install Ubuntu Notes ------------ You should install the following packages: sudo apt-get install build-essential autoconf libfltk1.3-dev \ libgnutls28-dev libjpeg-dev libpng-dev zlib1g-dev CentOS, Fedora, and RHEL Notes ------------------------------ The version of GCC bundled with older releases of these operating systems cannot handle the version of libpng that is bundled with HTMLDOC. Install the following packages to avoid this and get full functionality: sudo yum install autoconf fltk-devel gnutls-devel libjpeg-devel \ libpng-devel zlib-devel htmldoc-1.9.7/Makedefs.in000066400000000000000000000034151354715574200152510ustar00rootroot00000000000000# # Makefile definitions for HTMLDOC, an HTML document processing program. # # Copyright © 2011-2019 by Michael R Sweet. # Copyright © 1997-2010 by Easy Software Products. # # This program is free software.

HTMLDOC was developed in the 1990's as a documentation generator for my previous company, and has since seen a lot of usage as a report generator embedded in web servers. However, it does not support many things in "the modern web", such as: - Cascading Style Sheets (CSS): While I have experimented with adding CSS support to HTMLDOC, proper CSS support is non-trivial especially for paged output (which is not well supported by CSS) - Encryption: HTMLDOC currently supports the older (and very insecure) PDF 1.4 (128-bit RC4) encryption. I have looked at supporting AES (256-bit) encryption, however it is not widely supported and there are incompatible changes in PDF 2.0, so it is unlikely to be added to HTMLDOC. - Forms: HTML forms and PDF forms are very different things. While I have had many requests to add support for PDF forms over the years, I have not found a satisfactory way to do so. - Tables: HTMLDOC supports HTML 3.2 tables with basic support for TBODY and THEAD. - Unicode: While HTMLDOC does support UTF-8 for "Western" languages, there is absolutely no support for languages that require dynamic rewriting or right-to-left text formatting. Basically this means you can't use HTMLDOC to format Arabic, Chinese, Hebrew, Japanese, or other languages that are not based on latin-based alphabets that read left-to-right. - Emoji: The fonts bundled with HTMLDOC do not include Unicode Emoji characters. Resources --------- The following HTMLDOC resources are available online: - Official web site and online documentation: https://www.msweet.org/htmldoc - Issue tracker and questions: https://github.com/michaelrsweet/htmldoc/issues Using HTMLDOC ------------- Note: Complete documentation for HTMLDOC is available in the "doc" subdirectory. The following provides basic information on using HTMLDOC at the command-line and does not discuss the GUI or web server functionality. HTMLDOC accepts a list of HTML and/or Markdown "source" files and will generate EPUB, HTML, PostScript, or PDF output via command-line options. A summary of command-line options can be shown with the "--help" option: htmldoc --help HTMLDOC normally expects "structured" documents, with chapters, etc. Chapters begin with a H1 markup and continue to the end of the listed HTML files or the next H1 markup, whichever comes first. To convert unstructured documents such as web pages, use the "--webpage" option to HTMLDOC: htmldoc --webpage ... To generate a Level 2 PostScript file you might use: htmldoc -f outfile.ps chapter1.html ... chapterN.html Similarly you can generate an EPUB or PDF file of the same source files using: htmldoc -f outfile.epub chapter1.html ... chapterN.html htmldoc -f outfile.pdf chapter1.html ... chapterN.html Finally, to generate HTML files for viewing (with a linked table-of-contents) do the following: htmldoc -t html -d outdir chapter1.html ... chapterN.html or: htmldoc -t html -f outfile.html chapter1.html ... chapterN.html A complete description of all command-line options and HTML guidelines can be found in the software users manual in the "doc" directory. Credits ------- Many thanks to Leonard Rosenthol for providing the original changes to support a macOS (9) version of HTMLDOC. The original table VALIGN and "HALF PAGE" code was contributed by D. Richard Hipp. The original multiple header/footer image code was contributed by Lynn Pye. The RC4 encryption code is from librc4 1.1 by the folks at Carnegie Mellon University. The MD5 hash code is from L. Peter Deutsch at Aladdin Enterprises (creators of Ghostscript, among other things). Legal Stuff ----------- HTMLDOC is copyright © 1997-2019 by Michael R Sweet.

Chapter 1 - Introduction

This document describes how to use the HTMLDOC software. HTMLDOC reads HTML and Markdown source files or web pages and generates corresponding EPUB, HTML, PostScript, or PDF files with an optional table of contents. HTMLDOC can be used as a standalone application, in a batch document processing environment, or as a web-based report generation application.

HTMLDOC is open source software under the terms of version 2 of the GNU General Public License. No restrictions are placed upon the output produced by HTMLDOC.

History

Like many programs, I developed HTMLDOC in response to a need my company had for generating high-quality documentation in printed and electronic forms. For a while I used FrameMaker® and a package from sgi that generated "compiled" Standard Generalized Markup Language ("SGML") files that could be used by the Electronic Book Technologies ("EBT") documentation products; EBT was bought by INSO who was bought by StellentTM who apparently has dropped the whole product line. When sgi stopped supporting these tools I turned to INSO, but the cost of their tools was prohibitive to my small business.

In the end I decided to write my own program to generate the documentation. HTML seemed to be the source format of choice since WYSIWYG HTML editors are widely (and freely) available and at worst you can use a plain text editor. I needed HTML output for documentation on my web server, PDF for customers to read and/or print from their computers, and PostScript for printing needs.

The result of my efforts is the HTMLDOC software which runs on Linux®, macOS®, Microsoft® Windows®, and most UNIX® operating systems. Among other things, this software users manual is produced using HTMLDOC.

HTMLDOC used to be available under a commercial end-user license agreement from my former company, Easy Software Products. While that company is no longer in business, I continue to maintain HTMLDOC in my spare time.

Organization of This Manual

This manual is organized into tutorial and reference chapters and appendices:

Encryption Support

HTMLDOC includes code to encrypt PDF document files using the RC4 algorithm with up to a 128-bit key. While this software and code may be freely used and exported under current US laws, other countries may restrict your use and possession of this code and software.

Legal Stuff

HTMLDOC is copyright © 1997-2019 by Michael R Sweet. See Appendix A - License Agreement for the terms of use. This software is based in part on the work of the Independent JPEG Group and FLTK project.

Chapter 2 - Using HTMLDOC

This chapter describes the basics of how to use HTMLDOC to convert HTML and Markdown files into PostScript and PDF files.

Note: HTMLDOC currently does not support HTML 4.0 features such as stylesheets or the STYLE element. For more information, please consult Chapter 4 - HTML Reference.

Using the HTMLDOC GUI

After opening the HTMLDOC application, the HTMLDOC window will appear with the Input tab selected. Click on the Web Page radio button to specify that you will be converting a web page file. Then choose a file for conversion by clicking on the Add Files... button.

Now that you've chosen a file to be converted, click on the Output tab to set the output file and format. Finally, click on the Generate button at the bottom of the HTMLDOC window to convert the HTML file.

Generating Books

While HTMLDOC can convert web pages into PostScript and PDF files, its real strength is generating EPUB, indexed HTML, PostScript, or PDF books. HTMLDOC uses heading elements to delineate chapters and headings in a book. The H1 element is used for chapters:

<HTML>
<HEAD>
    <TITLE>The Little Computer that Could</TITLE>
</HEAD>
<BODY>
<H1>Chapter 1 - The Little Computer is Born</H1>
...
<H1>Chapter 2 - Little Computer's First Task</H1>
...
</BODY>
</HTML>

Sub-headings are marked using the H2 through H6 elements.

Note: When using book mode, HTMLDOC starts rendering with the first H1 element. Any text, images, tables, and other viewable elements that precede the first H1 element are silently ignored. Because of this, make sure you have an H1 element in your HTML file, otherwise HTMLDOC will not convert anything.

Start by clicking on the Book radio button to specify you'll be converting one or more files into a book. Then add one or more HTML or Markdown files by clicking on the Add Files... button.

HTMLDOC will automatically create a title page for you unless you specify a Title File/Image. When the title file is HTML or Markdown, the contents are formatted to produce title page(s). When the title file is an image, the image is centered on the title page with automatically generate content based on the title and other metadata.

After providing all of the input files, click on the Output tab to select the output format and file. Finally, click on the Generate button to generate the book.

Using the HTMLDOC Command

To convert a single web page type: 

htmldoc --webpage -f output.pdf filename.html ENTER

htmldoc is the name of the software.

The --webpage option specifies unstructured files with page breaks between each file.

The -f option specifies the output file name (output.pdf). In this example it is a PDF file.

Filename.html is the name of the file that you want to be converted.

To convert more than one web page with page breaks between each file, list each of the files on the end: 

htmldoc --webpage -f output.pdf file1.html file2.html ENTER

We've been using HTML files, but you can also use URLs. For example:

htmldoc --webpage -f output.pdf http://slashdot.org/ ENTER

Generating Books

Type one of the following commands to generate a book from one or more files: 

htmldoc --book -f output.html file1.html file2.html ENTER
htmldoc --book -f output.pdf file1.html file2.html ENTER
htmldoc --book -f output.ps file1.html file2.html ENTER

The --book option specifies that the input files are structured with headings.

The -f option specifies the output filename.

File1.html and file2.html are the files you want to convert.

HTMLDOC will build a table of contents for the book using the heading elements (H1, H2, etc.) in your input files. It will also add a title page using the document TITLE text and other META information you supply in your files. See Chapter 4 - HTML Reference for more information on the META variables that are supported.

Note: When using book mode, HTMLDOC starts rendering with the first H1 element. Any text, images, tables, and other viewable elements that precede the first H1 element are silently ignored. Because of this, make sure you have an H1 element in your HTML file, otherwise HTMLDOC will not convert anything.

Setting the Title File

The --titlefile option sets the HTML, Markdown, or image file to use on the title page:

htmldoc --titlefile filename.bmp ... ENTER
htmldoc --titlefile filename.gif ... ENTER
htmldoc --titlefile filename.jpg ... ENTER
htmldoc --titlefile filename.png ... ENTER
htmldoc --titlefile filename.html ... ENTER

HTMLDOC supports BMP, GIF, JPEG, and PNG images, as well as generic HTML or Markdown text you supply for the title page(s).

Using HTMLDOC on a Web Server

HTMLDOC can be used in a variety of ways to generate formatted reports on a web server. The most common way is to use HTMLDOC as a CGI program with your web server to provide PDF-formatted output of a web page. Examples are provided for Microsoft IIS and the Apache web servers.

HTMLDOC can also be called from your own server-side scripts and programs. Examples are provided for PHP and Java.

Warning: Passing information directly from the web browser to HTMLDOC can potentially expose your system to security risks. Always be sure to "sanitize" any input from the web browser so that filenames, URLs, and options passed to HTMLDOC are not acted on by the shell program or other processes. Filenames with spaces must usually be enclosed with quotes.

CGI Mode

HTMLDOC supports operation as a CGI program. You can copy or symlink the htmldoc (all but Windows) or htmldoc.exe (Windows) executable to your web server's cgi-bin directory and then use it to produce PDF versions of your web pages.

The CGI converts a page on your local server to PDF and sends it to the client's web browser. For example, to convert a page called superproducts.html at the following URL:

http://servername/superproducts.html

and if you installed HTMLDOC in your server's cgi-bin directory, you would direct your clients to the following URL:

http://servername/cgi-bin/htmldoc/superproducts.html

The boldface portion represents the location of the HTMLDOC executable on the web server. You simply place that path before the page you want to convert.

Form data using the GET method can be passed at the end of the URL, for example:

http://servername/cgi-bin/htmldoc/superproducts.html?name=value

Server-Side Preferences

When run as a CGI program, HTMLDOC will try to read a book file to set any preferences for the conversion to PDF. For the superproducts.html file described previously, HTMLDOC will look at the following URLs for a book file:

http://servername/superproducts.html.book
http://servername/.book
http://servername/cgi-bin/.book

The first book file that is found will be used.

Configuring HTMLDOC with Apache

The Apache web server is easily configured to use HTMLDOC. The simplest way is to copy or symlink the htmldoc executable to the configured cgi-bin directory. For example, if your Apache installation is configured to look for CGI programs in the /var/www/cgi-bin directory, the default for Apache on Red Hat Linux, then the command to install HTMLDOC on your web server would be:

ln -s /usr/bin/htmldoc /var/www/cgi-bin ENTER

If you are using Apache 2.0.30 or higher, you will also need to enable PATH_INFO support by adding the following line to your httpd.conf file:

AcceptPathInfo On

Apache also allows you to associate CGI programs with a specific extension. If you add the following line to your httpd.conf file:

AddHandler cgi-script .cgi

and enable CGI execution with the Options directive for a directory:

Options +ExecCGI

then you can copy or symlink the htmldoc executable to an alternate location. For example, if you have a web directory called /var/www/htdocs/products, you can install HTMLDOC in this directory with the following command:

ln -s /usr/bin/htmldoc /var/www/htdocs/products/htmldoc.cgi ENTER

Configuring HTMLDOC with Microsoft IIS

The IIS web server is configured to run CGI programs by either modifying the permissions of an existing directory or by creating a new virtual directory that allows for execution of programs. Start by running the Internet Services Manager program:

  1. Click on Start
  2. Click on Settings
  3. Click on Control Panel
  4. Double-click on Administrative Tools
  5. Double-click on Internet Services Manager

After the Internet Services Manager window appears, perform the following steps to add a virtual folder for HTMLDOC:

  1. Click on your server in the list to show the default web site service in the list
  2. Choose New->Virtual Directory from the Action menu
  3. Click Next when the Virtual Directory Creation Wizard window appears
  4. Enter the name htmldoc in the Alias field and click Next
  5. Enter the HTMLDOC program folder in the Directory field and click Next
  6. Check the Execute (such as ISAPI applications or CGI) box and click Next
  7. Click Finish to dismiss the wizard
  8. Click on Web Service Extensions
  9. Click Add a new Web Service Extension
  10. Enter the name "HTMLDOC" when the Web Service Extension window appears
  11. Click Add... and choose the htmldoc.exe file from the program folder, typically C:\Program Files\msweet.org\HTMLDOC
  12. Check the Set extension status to Allowed box
  13. Click OK to add the extension and dismiss the window

Finally, double-click the My Computer icon on the desktop or start the Windows Explorer. When the explorer window appears, perform the following steps to provide write access to the Windows temporary folder:

  1. Open the windows temporary file folder, typically C:\WINDOWS\TEMP
  2. Choose Properties from the File menu
  3. Click on the Security tab
  4. Click Add..., enter the username for the web server, typically "SERVER\IUSR_SERVER" where "SERVER" is the name you gave your server, and click OK
  5. Click on the username you just added in the list
  6. Check the Read and Write permissions
  7. Click OK to save the changes

Once configured, the htmldoc.exe program will be available in the web server directory. For example, for a virtual directory called cgi-bin, the PDF converted URL for the superproducts.html page would be as follows:

http://servername/cgi-bin/htmldoc.exe/superproducts.html

The boldface portion represents the location of the HTMLDOC program on the web server.

Using HTMLDOC From Server-Side Scripts and Programs

To make this work the CGI script or program must send the appropriate HTTP attributes, the required empty line to signify the beginning of the document, and then execute the HTMLDOC program to generate the HTML, PostScript, or PDF file as needed. Since HTMLDOC looks for CGI environment variables when it is run, you must also set the HTMLDOC_NOCGI environment variable to a value of 1 before running HTMLDOC from your CGI script or program.

Another way to generate PDF files from your reports is to use HTMLDOC as a "portal" application. When used as a portal, HTMLDOC automatically retrieves the named document or report from your server and passes a PDF version to the web browser. See the next sections for more information.

Calling HTMLDOC from a Shell Script

Shell scripts are probably the easiest to work with, but are normally limited to GET type requests. Here is a script called topdf that acts as a portal, converting the named file to PDF:

#!/bin/sh
#
# Sample "portal" script to convert the named HTML file to PDF on-the-fly.
#
# Usage: http://www.example.com/path/topdf/path/filename.html
#

#
# Tell HTMLDOC not to run in CGI mode...
#

HTMLDOC_NOCGI=1; export HTMLDOC_NOCGI

#
# The "options" variable contains any options you want to pass to HTMLDOC.
#

options='-t pdf --webpage --header ... --footer ..."

#
# Tell the browser to expect a PDF file...
#

echo "Content-Type: application/pdf"
echo ""

#
# Run HTMLDOC to generate the PDF file...
#

htmldoc $options http://${SERVER_NAME}:${SERVER_PORT}$PATH_INFO

Users of this CGI would reference the URL "http://www.example.com/topdf.cgi/index.html" to generate a PDF file of the site's home page.

The options variable in the script can be set to use any supported command-line option for HTMLDOC; for a complete list see Chapter 3 - Command-Line Reference.

Calling HTMLDOC from Perl

Perl scripts offer the ability to generate more complex reports, pull data from databases, etc. The easiest way to interface Perl scripts with HTMLDOC is to write a report to a temporary file and then execute HTMLDOC to generate the PDF file.

Here is a simple Perl subroutine that can be used to write a PDF report to the HTTP client:

sub topdf {
    # Get the filename argument...
    my $filename = shift;

    # Make stdout unbuffered...
    select(STDOUT); $| = 1;

    # Tell HTMLDOC not to run in CGI mode...
    $ENV{HTMLDOC_NOCGI} = 1;

    # Write the content type to the client...
    print "Content-Type: application/pdf\n\n";

    # Run HTMLDOC to provide the PDF file to the user...
    system "htmldoc -t pdf --quiet --webpage $filename";
}

Calling HTMLDOC from PHP

PHP provides a passthru() function that can be used to run HTMLDOC. This combined with the header() function can be used to provide on-the-fly reports in PDF format.

Here is a simple PHP function that can be used to convert a HTML report to PDF and send it to the HTTP client:

function topdf($filename, $options = "") {
    # Tell HTMLDOC not to run in CGI mode...
    putenv("HTMLDOC_NOCGI=1");

    # Write the content type to the client...
    header("Content-Type: application/pdf");
    flush();

    # Run HTMLDOC to provide the PDF file to the user...
    passthru("htmldoc -t pdf --quiet --jpeg --webpage $options " . escapeshellarg($filename));
}

The function accepts a filename and an optional "options" string for specifying the header, footer, fonts, etc.

To make a "portal" script, add the following code to complete the example:

global $SERVER_NAME;
global $SERVER_PORT;
global $PATH_INFO;
global $QUERY_STRING;

if ($QUERY_STRING != "") {
    $url = "http://${SERVER_NAME}:${SERVER_PORT}${PATH_INFO}?${QUERY_STRING}";
} else {
    $url = "http://${SERVER_NAME}:${SERVER_PORT}$PATH_INFO";
}

topdf($url);

Calling HTMLDOC from C

C programs offer the best flexibility and easily supports on-the-fly report generation without the need for temporary files.

Here are some simple C functions that can be used to generate a PDF report to the HTTP client from a temporary file or pipe:

#include <stdio.h>
#include <stdlib.h>


/* topdf() - convert a HTML file to PDF */
FILE *topdf(const char *filename)       /* I - HTML file to convert */
{
  char	command[1024];			/* Command to execute */


 /*
  * Tell HTMLDOC not to run in CGI mode...
  */

  putenv("HTMLDOC_NOCGI=1");

 /*
  * Write the content type to the client...
  */

  puts("Content-Type: application/pdf\n");

 /*
  * Run HTMLDOC to provide the PDF file to the user...
  */

  sprintf(command, "htmldoc --quiet -t pdf --webpage %s", filename);

  return (popen(command, "w"));
}


/* topdf2() - pipe HTML output to HTMLDOC for conversion to PDF */
FILE *topdf2(void)
{
 /*
  * Tell HTMLDOC not to run in CGI mode...
  */

  putenv("HTMLDOC_NOCGI=1");

 /*
  * Write the content type to the client...
  */

  puts("Content-Type: application/pdf\n");

 /*
  * Open a pipe to HTMLDOC...
  */

  return (popen("htmldoc --quiet -t pdf --webpage -", "w"));
}

Calling HTMLDOC from Java

Java programs are a portable way to add PDF support to your web server. Here is a class called htmldoc that acts as a portal, converting the named file to PDF. It can also be called by your Java servlets to process an HTML file and send the result to the client in PDF format:

class htmldoc
{
  // Convert named file to PDF on stdout...
  public static int topdf(String filename)// I - Name of file to convert
  {
    String              command;          // Command string
    Process             process;          // Process for HTMLDOC
    Runtime             runtime;          // Local runtime object
    java.io.InputStream input;            // Output from HTMLDOC
    byte                buffer [];        // Buffer for output data
    int                 bytes;            // Number of bytes


    // First tell the client that we will be sending PDF...
    System.out.print("Content-type: application/pdf\n\n");

    // Construct the command string
    command = "htmldoc --quiet --jpeg --webpage -t pdf --left 36 " +
              "--header .t. --footer .1. " + filename;

    // Run the process and wait for it to complete...
    runtime = Runtime.getRuntime();

    try
    {
      // Create a new HTMLDOC process...
      process = runtime.exec(command);

      // Get stdout from the process and a buffer for the data...
      input  = process.getInputStream();
      buffer = new byte[8192];

      // Read output from HTMLDOC until we have it all...
      while ((bytes = input.read(buffer)) > 0)
        System.out.write(buffer, 0, bytes);

      // Return the exit status from HTMLDOC...
      return (process.waitFor());
    }
    catch (Exception e)
    {
      // An error occurred - send it to stderr for the web server...
      System.err.print(e.toString() + " caught while running:\n\n");
      System.err.print("    " + command + "\n");
      return (1);
    }
  }

  // Main entry for htmldoc class
  public static void main(String[] args)// I - Command-line args
  {
    String server_name,                 // SERVER_NAME env var
           server_port,                 // SERVER_PORT env var
           path_info,                   // PATH_INFO env var
           query_string,                // QUERY_STRING env var
           filename;                    // File to convert


    if ((server_name = System.getProperty("SERVER_NAME")) != null &&
        (server_port = System.getProperty("SERVER_PORT")) != null &&
        (path_info = System.getProperty("PATH_INFO")) != null)
    {
      // Construct a URL for the resource specified...
      filename = "http://" + server_name + ":" + server_port + path_info;

      if ((query_string = System.getProperty("QUERY_STRING")) != null)
      {
        filename = filename + "?" + query_string;
      }
    }
    else if (args.length == 1)
    {
      // Pull the filename from the command-line...
      filename = args[0];
    }
    else
    {
      // Error - no args or env variables!
      System.err.print("Usage: htmldoc.class filename\n");
      return;
    }

    // Convert the file to PDF and send to the web client...
    topdf(filename);
  }
}

Chapter 3 - Command-Line Reference

This chapter describes all of the command-line options supported by HTMLDOC.

Basic Usage

The basic command-line usage for HTMLDOC is: 

% htmldoc options filename1.html ... filenameN.md ENTER
% htmldoc options filename.book ENTER

The first form converts the named HTML or Markdown files to the specified output format immediately. The second form loads the specified .book file and displays the HTMLDOC window, allowing a user to make changes and/or generate the document interactively.

If no output file or directory is specified, then all output is sent to the standard output file.

On return, HTMLDOC returns an exit code of 0 if it was successful and non-zero if there were errors.

Options

The following command-line options are recognized by HTMLDOC.

-d directory

The -d option specifies an output directory for the document files.

This option is not compatible with the EPUB or PDF output formats.

-f filename

The -f option specifies an output file for the document.

-t format

The -t option specifies the output format for the document and can be one of the following:

FormatDescription

Environment Variables

HTMLDOC looks for several environment variables which can override the default directories, display additional debugging information, and disable CGI mode.

HTMLDOC_DATA

This environment variable specifies the location of HTMLDOC's data and fonts directories, normally /usr/share/htmldoc or C:\Program Files\HTMLDOC.

HTMLDOC_DEBUG

This environment variable enables debugging information that is sent to stderr. The value is a list of keywords separated by spaces:

keywordInformation Shown
linksShows all of the links in a document
memoryShows memory usage statistics
remotebytesShows the number of bytes that were transferred via HTTP
tablePuts a box around each table, row, and cell
tempfilesShows the temporary files that were created, and preserves them for debugging
timingShows the load and render times
allAll of the above

HTMLDOC_HELP

This environment variable specifies the location of HTMLDOC's documentation directory, normally /usr/share/doc/htmldoc or C:\Program Files\HTMLDOC\doc.

HTMLDOC_NOCGI

This environment variable, when set (the value doesn't matter), disables CGI mode. It is most useful for using HTMLDOC on a web server from a scripting language or invocation from a program.

Messages

HTMLDOC sends error and status messages to stderr unless the --quiet option is provided on the command-line. Applications can capture these messages to relay errors or statistics to the user.

BYTES: Message

The BYTES: message specifies the number of bytes that were written to an output file. If the output is directed at a directory then multiple BYTES: messages will be sent.

DEBUG: Messages

The DEBUG: messages contain debugging information based on the value of the HTMLDOC_DEBUG environment variable. Normally, no DEBUG: messages are sent by HTMLDOC.

ERRnnn: Messages

The ERRnnn: messages specify an error condition. Error numbers 1 to 14 map to the following errors:

  1. No files were found or loadable.
  2. No pages were generated.
  3. The document contains too many files or chapters.
  4. HTMLDOC ran out of memory.
  5. The specified file could not be found.
  6. The comment contains a bad HTMLDOC formatting command.
  7. The image file is not in a known format.
  8. HTMLDOC was unable to remove a temporary file.
  9. HTMLDOC had an unspecified internal error.
  10. HTMLDOC encountered a networking error when retrieving a file via a URL.
  11. HTMLDOC was unable to read a file.
  12. HTMLDOC was unable to write a file.
  13. A HTML error was found in a source file.
  14. A table, image, or text fragment was too large to fit in the space provided.
  15. A hyperlink in the source files was unresolved.
  16. A header/footer string in the document contains a bad $ command.

Error numbers 100 to 505 correspond directly to a HTTP status code.

INFO: Messages

The INFO: messages contain general information that is logged when HTMLDOC is running in CGI mode or when you use the --verbose option.

PAGES: Message

The PAGES: message specifies the number of pages that were written to an output file. If the output is directed at a directory then multiple PAGES: messages will be sent. No PAGES: messages are sent when generating HTML or EPUB output.

REMOTEBYTES: Message

The REMOTEBYTES: message specifies the number of bytes that were transferred using HTTP. This message is only displayed if the HTMLDOC_DEBUG environment variable has the keyword remotebytes or all.

TIMING: Message

The TIMING: message specifies the load, render, and total time in seconds for the current command. This message is only displayed if the HTMLDOC_DEBUG environment variable has the keyword timing or all.

Chapter 4 - HTML Reference

This chapter defines all of the HTML elements and attributes that are recognized and supported by HTMLDOC.

General Usage

There are two types of HTML files - structured documents using headings (H1, H2, etc.) which HTMLDOC calls "books", and unstructured documents that do not use headings which HTMLDOC calls "web pages".

A very common mistake is to try converting a web page using: 

htmldoc -f filename.pdf filename.html

which will likely produce a PDF file with no pages. To convert web page files you must use the --webpage option at the command-line or choose Web Page in the input tab of the GUI.

Note: HTMLDOC does not support HTML 4.0 elements, attributes, stylesheets, or scripting.

Comments

HTMLDOC supports many special HTML comments to initiate page breaks, set the header and footer text, and control the current media options:

<!-- FOOTER LEFT "foo" -->
Sets the left footer text; the test is applied to the current page if empty, or the next page otherwise.
<!-- FOOTER CENTER "foo" -->
Sets the center footer text; the test is applied to the current page if empty, or the next page otherwise.
<!-- FOOTER RIGHT "foo" -->
Sets the right footer text; the test is applied to the current page if empty, or the next page otherwise.

Header/Footer Strings

The HEADER and FOOTER comments allow you to set an arbitrary string of text for the left, center, and right headers and footers. Each string consists of plain text; special values or strings can be inserted using the dollar sign ($):

$$
Inserts a single dollar sign in the header.
$CHAPTER
Inserts the current chapter heading.
$CHAPTERPAGE
$CHAPTERPAGE(format)
Inserts the current page number within a chapter or file. When a format is specified, uses that numeric format (1 = decimal, i = lowercase roman numerals, I = uppercase roman numerals, a = lowercase ascii, A = uppercase ascii) for the page numbers.
$CHAPTERPAGES
$CHAPTERPAGES(format)
Inserts the total page count within a chapter or file. When a format is specified, uses that numeric format (1 = decimal, i = lowercase roman numerals, I = uppercase roman numerals, a = lowercase ascii, A = uppercase ascii) for the page count.

FONT Attributes

Limited typeface specification is currently supported to ensure portability across platforms and for older PostScript printers:

Requested FontActual Font
ArialHelvetica
CourierCourier
DingbatsDingbats
HelveticaHelvetica
MonospaceDejaVu Sans Mono
SansDejaVu Sans
SerifDejaVu Serif
SymbolSymbol
TimesTimes

All other unrecognized typefaces are silently ignored.

Headings

Currently HTMLDOC supports a maximum of 1000 chapters (H1 headings). This limit can be increased by changing the MAX_CHAPTERS constant in the config.h file included with the source code.

All chapters start with a top-level heading (H1) markup. Any headings within a chapter must be of a lower level (H2 to H15). Each chapter starts a new page or the next odd-numbered page if duplexing is selected.

Note: Heading levels 7 to 15 are not standard HTML and will not likely be recognized by most web browsers.

The headings you use within a chapter must start at level 2 (H2). If you skip levels the heading will be shown under the last level that was known. For example, if you use the following hierarchy of headings: 

<H1>Chapter Heading</H1>
...
<H2>Section Heading 1</H2>
...
<H2>Section Heading 2</H2>
...
<H3>Sub-Section Heading 1</H3>
...
<H4>Sub-Sub-Section Heading 1</H4>
...
<H4>Sub-Sub-Section Heading 2</H4>
...
<H3>Sub-Section Heading 2</H3>
...
<H2>Section Heading 3</H2>
...
<H4>Sub-Sub-Section Heading 3</H4>
...
the table-of-contents that is generated will show:
  • Chapter Heading
    • Section Heading 1
    • Section Heading 2
      • Sub-Section Heading 1
        • Sub-Sub-Section Heading 1
        • Sub-Sub-Section Heading 2
      • Sub-Section Heading 2
        • Sub-Sub-Section Heading 3
    • Section Heading 3

Numbered Headings

When the numbered headings option is enabled, HTMLDOC recognizes the following additional attributes for all heading elements:
VALUE="#"
Specifies the starting value for this heading level (default is "1" for all new levels).
TYPE="1"
Specifies that decimal numbers should be generated for this heading level.
TYPE="a"
Specifies that lowercase letters should be generated for this heading level.
TYPE="A"
Specifies that uppercase letters should be generated for this heading level.
TYPE="i"
Specifies that lowercase roman numerals should be generated for this heading level.
TYPE="I"
Specifies that uppercase roman numerals should be generated for this heading level.

Images

HTMLDOC supports loading of BMP, GIF, JPEG, and PNG image files. EPS and other types of image files are not supported at this time.

Links

External URL and internal (#target and filename.html) links are fully supported for HTML and PDF output.

When generating PDF files, local PDF file links will be converted to external file links for the PDF viewer instead of URL links. That is, you can directly link to another local PDF file from your HTML document with: 

<A HREF="filename.pdf">...</A>

META Attributes

HTMLDOC supports the following META attributes for the title page and document information:

<META NAME="AUTHOR" CONTENT="..."
Specifies the document author.
<META NAME="COPYRIGHT" CONTENT="..."
Specifies the document copyright.
<META NAME="DOCNUMBER" CONTENT="..."
Specifies the document number.
<META NAME="GENERATOR" CONTENT="..."
Specifies the application that generated the HTML file.
<META NAME="KEYWORDS" CONTENT="..."
Specifies document search keywords.
<META NAME="SUBJECT" CONTENT="..."
Specifies document subject.

Tables

Currently HTMLDOC supports a maximum of 200 columns within a single table. This limit can be increased by changing the MAX_COLUMNS constant in the config.h file included with the source code.

HTMLDOC does not support HTML 4.0 table elements or attributes, such as TBODY, THEAD, TFOOT, or RULES.

Chapter 5 - Markdown Reference

This chapter describes the markdown syntax that is recognized and supported by HTMLDOC.

General Syntax

Markdown is a simple plain-text format that uses formatting conventions that are commonly used in email and other text-based communications. Markdown is used by most of the major blogging, web site, and project hosting platforms and is supported by many standalone text editors.

HTMLDOC supports the CommonMark version of markdown syntax with the following exceptions:

  • Metadata as used by Jekyll and other web markdown solutions can be placed at the beginning of the file;
  • "@" links can be used which resolve to headings within the file;
  • Tables can be embedded using the "|" separator;
  • Embedded HTML markup and entities are explicitly not supported or allowed;
  • Tabs are silently expanded to the markdown standard of four spaces since HTML uses eight spaces per tab; and
  • Some pathological nested link and inline style features supported by CommonMark (******Really Strong Text******) are not supported by mmd.
Note: HTMLDOC does not support embedded HTML in markdown documents because the version of HTML (or XHTML) cannot be reliably determined, making support of certain character entities and language elements problematic.

Metadata Syntax

Metadata is specified at the top of a markdown file between two lines containing three hyphens, for example:

---
title: My Great Novel
author: John Doe
copyright: Copyright © 2018 by John Doe
version: 1.0
language: en-US
subject: Fiction
---

# Preamble

...

HTMLDOC supports the "author", "copyright", "language", "subject", "title", and "version" metadata and silently ignores everything else.

Link Targets and @ Links

CommonMark defines no standard for how implementations generate anchors or identifiers for headings in a markdown file - this makes hyperlinking to a named section within a document basically impossible. Jekyll and other markdown implementations allow the special link "@" to be used, which HTMLDOC supports:

See [Screwing in a Light Bulb](@) for instructions on installing a
light bulb.

...

# Screwing in a Light Bulb

...

To reference a markdown heading from a HTML file, convert the heading to lowercase, replace spaces with the hyphen ("-"), and remove any special characters. Thus, a HTML file would reference the previous heading using the following HTML:

<a href="#screwing-in-a-light-bulb"> ... </a>

Table Syntax

CommonMark does not define a syntax for plain-text tables, instead relying on embedded HTML which HTMLDOC does not support. Both Github and Jekyll support a common markdown extension for plain text tables that uses the vertical pipe ("|") character to specify column separations. The first line contains the table header, the second line is a horizontal separator, and the remaining lines contain the table body. For example:

| Heading 1 | Heading 2 | Heading 3 |

| Cell 1,1  | Cell 1,2  | Cell 1,3  |
| Cell 2,1  | Cell 2,2  | Cell 2,3  |
| Cell 3,1  | Cell 3,2  | Cell 3,3  |

will produce:

Heading 1Heading 2Heading 3
Cell 1,1Cell 1,2Cell 1,3
Cell 2,1Cell 2,2Cell 2,3
Cell 3,1Cell 3,2Cell 3,3

The outer pipes can be omitted, for example:

Heading 1 | Heading 2 | Heading 3
--------- | --------- | ---------
Cell 1,1  | Cell 1,2  | Cell 1,3
Cell 2,1  | Cell 2,2  | Cell 2,3
Cell 3,1  | Cell 3,2  | Cell 3,3

While table headings are always centered, you can control the alignment of the body cells by using the colon (":") character in the separator line. Put a leading colon to specify left alignment (the default), a trailing colon for right alignment, or both to specify centering. For example:

Left Alignment | Center Alignment | Right Alignment
:------------- | :--------------: | --------------:
Cell 1,1       |     Cell 1,2     |               1
Cell 2,1       |     Cell 2,2     |              12
Cell 3,1       |     Cell 3,2     |             123

will produce:

Left AlignmentCenter AlignmentRight Alignment
Cell 1,1Cell 1,21
Cell 2,1Cell 2,212
Cell 3,1Cell 3,2123

Table columns do not need to be padded so that they line up - the following (less readable) example is perfectly valid:

Left Alignment|Center Alignment|Right Alignment
:--|:--:|--:
Cell 1,1|Cell 1,2|1
Cell 2,1|Cell 2,2|12
Cell 3,1|Cell 3,2|123

Appendix A - License Agreement

GNU GENERAL PUBLIC LICENSE

Version 2, June 1991 

Copyright 1989, 1991 Free Software Foundation, Inc.
59 Temple Place, Suite 330, Boston, MA 02111-1307 USA

Everyone is permitted to copy and distribute verbatim
copies of this license document, but changing it is not allowed.

Preamble

The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This General Public License applies to most of the Free Software Foundation's software and to any other program whose authors commit to using it. (Some other Free Software Foundation software is covered by the GNU Library General Public License instead.) You can apply it to your programs, too.

When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs; and that you know you can do these things.

To protect your rights, we need to make restrictions that forbid anyone to deny you these rights or to ask you to surrender the rights. These restrictions translate to certain responsibilities for you if you distribute copies of the software, or if you modify it.

For example, if you distribute copies of such a program, whether gratis or for a fee, you must give the recipients all the rights that you have. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights.

We protect your rights with two steps: (1) copyright the software, and (2) offer you this license which gives you legal permission to copy, distribute and/or modify the software.

Also, for each author's protection and ours, we want to make certain that everyone understands that there is no warranty for this free software. If the software is modified by someone else and passed on, we want its recipients to know that what they have is not the original, so that any problems introduced by others will not reflect on the original authors' reputations.

Finally, any free program is threatened constantly by software patents. We wish to avoid the danger that redistributors of a free program will individually obtain patent licenses, in effect making the program proprietary. To prevent this, we have made it clear that any patent must be licensed for everyone's free use or not licensed at all.

The precise terms and conditions for copying, distribution and modification follow.

GNU GENERAL PUBLIC LICENSE
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION

  1. This License applies to any program or other work which contains a notice placed by the copyright holder saying it may be distributed under the terms of this General Public License. The "Program", below, refers to any such program or work, and a "work based on the Program" means either the Program or any derivative work under copyright law: that is to say, a work containing the Program or a portion of it, either verbatim or with modifications and/or translated into another language. (Hereinafter, translation is included without limitation in the term "modification".) Each licensee is addressed as "you".

    Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running the Program is not restricted, and the output from the Program is covered only if its contents constitute a work based on the Program (independent of having been made by running the Program). Whether that is true depends on what the Program does.

  2. You may copy and distribute verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and give any other recipients of the Program a copy of this License along with the Program.

    You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee.

  3. You may modify your copy or copies of the Program or any portion of it, thus forming a work based on the Program, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions:
    1. You must cause the modified files to carry prominent notices stating that you changed the files and the date of any change.
    2. You must cause any work that you distribute or publish, that in whole or in part contains or is derived from the Program or any part thereof, to be licensed as a whole at no charge to all third parties under the terms of this License.
    3. if the modified program normally reads commands interactively when run, you must cause it, when started running for such interactive use in the most ordinary way, to print or display an announcement including an appropriate copyright notice and a notice that there is no warranty (or else, saying that you provide a warranty) and that users may redistribute the program under these conditions, and telling the user how to view a copy of this License. (Exception: if the Program itself is interactive but does not normally print such an announcement, your work based on the Program is not required to print an announcement.)

    These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Program, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Program, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it.

    Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Program.

    In addition, mere aggregation of another work not based on the Program with the Program (or with a work based on the Program) on a volume of a storage or distribution medium does not bring the other work under the scope of this License.

  4. You may copy and distribute the Program (or a work based on it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you also do one of the following:
    1. Accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or,
    2. Accompany it with a written offer, valid for at least three years, to give any third party, for a charge no more than your cost of physically performing source distribution, a complete machine-readable copy of the corresponding source code, to be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or,
    3. Accompany it with the information you received as to the offer to distribute corresponding source code. (This alternative is allowed only for noncommercial distribution and only if you received the program in object code or executable form with such an offer, in accord with Subsection b above.)

    The source code for a work means the preferred form of the work for making modifications to it. For an executable work, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the executable. However, as a special exception, the source code distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable.

    If distribution of executable or object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place counts as distribution of the source code, even though third parties are not compelled to copy the source along with the object code.

  5. You may not copy, modify, sublicense, or distribute the Program except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense or distribute the Program is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance.
  6. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Program or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Program (or any work based on the Program), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Program or works based on it.
  7. Each time you redistribute the Program (or any work based on the Program), the recipient automatically receives a license from the original licensor to copy, distribute or modify the Program subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties to this License.
  8. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Program at all. For example, if a patent license would not permit royalty-free redistribution of the Program by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Program.

    If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply and the section as a whole is intended to apply in other circumstances.

    It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system, which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice.

    This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License.

  9. If the distribution and/or use of the Program is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Program under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License.
  10. The Free Software Foundation may publish revised and/or new versions of the General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns.

    Each version is given a distinguishing version number. If the Program specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of this License, you may choose any version ever published by the Free Software Foundation.

  11. If you wish to incorporate parts of the Program into other free programs whose distribution conditions are different, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally.

NO WARRANTY

  1. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
  2. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

END OF TERMS AND CONDITIONS

How to Apply These Terms to Your New Programs

If you develop a new program, and you want it to be of the greatest possible use to the public, the best way to achieve this is to make it free software which everyone can redistribute and change under these terms.

To do so, attach the following notices to the program. It is safest to attach them to the start of each source file to most effectively convey the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found. 

one line to give the program's name and an idea of what it does.
Copyright (C) yyyy  name of author

This program is free software; you can redistribute it and/or
modify it under the terms of the GNU General Public License
as published by the Free Software Foundation; either version 2
of the License, or (at your option) any later version.

This program is distributed in the hope that it will be useful,
but WITHOUT ANY WARRANTY; without even the implied warranty of
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
GNU General Public License for more details.

You should have received a copy of the GNU General Public License
along with this program; if not, write to the Free Software
Foundation, Inc., 59 Temple Place - Suite 330, Boston, MA  02111-1307, USA.

Also add information on how to contact you by electronic and paper mail.

If the program is interactive, make it output a short notice like this when it starts in an interactive mode: 

Gnomovision version 69, Copyright (C) year name of author
Gnomovision comes with ABSOLUTELY NO WARRANTY; for details
type `show w'.  This is free software, and you are welcome
to redistribute it under certain conditions; type `show c'
for details.

The hypothetical commands `show w' and `show c' should show the appropriate parts of the General Public License. Of course, the commands you use may be called something other than `show w' and `show c'; they could even be mouse-clicks or menu items--whatever suits your program.

You should also get your employer (if you work as a programmer) or your school, if any, to sign a "copyright disclaimer" for the program, if necessary. Here is a sample; alter the names: 

Yoyodyne, Inc., hereby disclaims all copyright
interest in the program `Gnomovision'
(which makes passes at compilers) written
by James Hacker.

Appendix B - Book File Format

This appendix describes the HTMLDOC .book file format.

Introduction

The HTMLDOC .book file format is a simple text format that provides the command-line options and files that are part of the document. These files can be used from the GUI interface or from the command-line using the --batch option: 

htmldoc filename.book
htmldoc --batch filename.book

The first form will load the book and display the GUI interface, if configured. Windows users should use ghtmldoc.exe executable to show the GUI and htmldoc.exe for the batch mode: 

ghtmldoc.exe filename.book
htmldoc.exe --batch filename.book

The Header

Each .book file starts with a line reading: 

#HTMLDOC 1.9

The version number (1.9) is optional.

The Options

Following the header is a line containing the options for the book. You can use any valid command-line option on this line: 

-f htmldoc.pdf --titleimage htmldoc.png --duplex --compression=9 --jpeg=90

Long option lines can be broken using a trailing backslash (\) on the end of each continuation line:

-f htmldoc.pdf --titleimage htmldoc.png --duplex \
--compression=9 --jpeg=90

The Files

Following the options are a list of files or URLs to include in the document: 

1-intro.html
2-using.html
3-cmdref.html
4-htmlref.html
5-mdref.html
a-license.html
b-book.html

Putting It All Together

The following is the complete book file needed to generate this documentation:

The Input Tab

The input tab lists all of the source files that are used to generate the document. You can also specify the type of document (book or web page) and the title and logo images.

Setting the Document Type

Normally HTMLDOC generates indexed documents from your structured source files. To convert a single unstructured document (or "web page") click on the Continuous or Web Page radio buttons. The Web Page type inserts page breaks between each file or URL, while the Continuous type does not.

Structured HTML files use heading elements (H1, H2, etc.) to delineate chapters and headings within a document.

Adding Input Files

Click on the Add File(s)... button to add one or more HTML or Markdown files to your .BOOK file.

Adding URLs

Click on the Add URL(s)... button to add one or more URLs to your .BOOK file.

Deleting Input Files

Highlight the file(s) in the input file list and then click on the Delete button to remove one or more source files from your document. The files are removed from your document but are not deleted from disk.

Editing Input Files

Highlight the file(s) in the input file list and then click on the Edit... button to edit one or more source files in your document. By default this starts the gedit editor under Linux, the bbedit editor under macOS, and the Notepad editor under Windows.

The editor can be changed in the Options Tab.

Reordering Input Files

Highlight the file(s) in the input file list and then click on the Move Up or Move Down buttons to change the order of the input files.

Selecting a Logo Image

The logo image can be shown in the header or footer of pages in the PostScript and PDF output files. Click on the Browse button to select a logo image file using the file chooser.

Selecting a Title File or Image

The title file or image is used for the title page. Click on the Browse button to select a title file using the file chooser.

The Output Tab

The output tab specifies where your document will be generated, the output format, and some of the output options.

Selecting File or Directory Generation

HTMLDOC can generate a single EPUB, HTML, PDF, or PostScript file, or a series of files to a directory when generating HTML or PostScript output.

Click on the File radio button to select single file output. Click on the Directory radio button to generate multiple files to a directory.

Selecting an Output File or Directory

The output file is the EPUB, HTML, PostScript, or PDF file you wish to generate from your source files. Click on the Browse button to select an output file using the file chooser.

Selecting the Output Format

Click on the corresponding Output Type radio button to select an output format. You can select the PostScript language level in the PS Tab and the PDF version in the PDF Tab.

Selecting Grayscale Output

When generating PostScript or PDF files you can choose to convert all images to grayscale. This is necessary for many Level 1 printers that do not support color images and can reduce the size of output files considerably.

Click in the Grayscale check box to enable or disable grayscale output.

Title Page

The title page is the first page in your generated file. Click in the Title Page check box to turn the title page on or off.

JPEG Big Images

JPEG compression is a great way to reduce the size of large photographic or continuous-tone images. It is supported when generating PDF, PostScript Level 2, and PostScript Level 3 output. HTMLDOC uses JPEG compression when the output image cannot be reduced to 256 colors or less.

Click in the JPEG Big Images check box to enable or disable JPEG compression.

JPEG Quality

Drag the JPEG Quality slider to change the JPEG quality setting. The JPEG quality setting determines the relative quality of the compressed image. Since JPEG is a lossy compression algorithm, higher compression generally yields lower quality. Typically a quality of 75 or higher provides excellent image quality with a high amount of compression.

Compression

PDF 1.2, PDF 1.3, PDF 1.4, and Level 3 PostScript files can be compressed using Flate (a.k.a. ZIP) compression to substantially reduce the size of files. Drag the Compression slider to set the amount of compression to use.

Unlike JPEG, the Flate algorithm is lossless and will not cause any loss of visual quality at any level of compression.

The Page Tab

The page tab defines the page header, footer, size, and margins for PostScript and PDF output.

Page Size

The page size option is only available for PostScript and PDF output. HTMLDOC supports the following standard page size names:

  • A3 - 11.69x16.54in (297x420mm)
  • A4 - 8.27x11.69in (210x297mm)
  • Legal - 8.5x14in (216x356mm)
  • Letter - 8.5x11in (216x279mm)
  • Tabloid - 11x17in (279x432mm)
  • Universal - 8.27x11in (210x279mm)

Click on the Page Size arrow button to select a standard page size. You can specify a custom page size by double-clicking on the page size text and entering the page width and length separated by the letter "x". Append the letters "in" for inches, "mm" for millimeters, or "cm" for centimeters.

Note: This option does not set the page size on the printer. It only generates pages using the specified size. See the PS Tab to enable printer commands for PostScript printers.

2-Sided

Click in the 2-Sided check box to select double-sided (duplexed) output.

Note: This option does not select duplexing on the printer. It only generates pages with the left/right margins swapped on even numbered pages and forces all chapters (and the table-of-contents) to start on an odd-numbered page. See the PS Tab to enable printer commands for PostScript printers.

Landscape

Click in the Landscape check box to select landscape output.

Page Margins

The left, right, top, and bottom margins can be changed by clicking in the appropriate text field and entering a new margin. Append the letters "in" for inches, "mm" for millimeters, or "cm" for centimeters.

Header and Footer

Select the desired text from each of the option buttons to customize the header and footer for the document/body pages. The left option buttons set the text that is left-justified, the middle buttons set the text that is centered, and the right buttons set the text that is right-justified.

The left and right header and footer are swapped automatically when generating duplexed output.

Number Up

The Number Up chooser selects the number of document pages that will appear on each output page. Click on the chooser to select a different number of pages.

The Table-Of-Contents Tab

The table-of-contents tab defines the number of levels in the table-of-contents and the page header and footer that are used when generating PostScript and PDF files.

Customizing the Table of Contents

To change the number of header levels listed in the table of contents, or to turn off table-of-contents generation entirely, click on Table of Contents chooser and select the number of levels desired.

Numbering Table of Contents Headings

To number the headings in your document, click on the Numbered Headings toggle button.

Customizing the Header and Footer

To customize the header and footer for the table-of-contents pages, select the desired text from each of the option buttons. The leftmost option buttons set the text that is left-justified, while the middle buttons set the text that is centered and the right buttons set the text that is right-justified.

Title

Enter the desired title for the table-of-contents in the Title field.

    For example, if you distribute copies of such a program, whether " "gratis or for a fee, you must give the recipients all the rights that " "you have. You must make sure that they, too, receive or can get the " "source code. And you must show them these terms so they know their " "rights. " "

    We protect your rights with two steps: (1) copyright the software, and " "(2) offer you this license which gives you legal permission to copy, " "distribute and/or modify the software. " "

    Also, for each author's protection and ours, we want to make certain " "that everyone understands that there is no warranty for this free " "software. If the software is modified by someone else and passed on, we " "want its recipients to know that what they have is not the original, so " "that any problems introduced by others will not reflect on the original " "authors' reputations. " "

    Finally, any free program is threatened constantly by software " "patents. We wish to avoid the danger that redistributors of a free " "program will individually obtain patent licenses, in effect making the " "program proprietary. To prevent this, we have made it clear that any " "patent must be licensed for everyone's free use or not licensed at all. " "

    The precise terms and conditions for copying, distribution and " "modification follow. " "

    GNU GENERAL PUBLIC LICENSE
    \n" "TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION

    \n" "

    0. This License applies to any program or other work which contains " "a notice placed by the copyright holder saying it may be distributed " "under the terms of this General Public License. The \"Program\", below, " "refers to any such program or work, and a \"work based on the Program\" " "means either the Program or any derivative work under copyright law: " "that is to say, a work containing the Program or a portion of it, " "either verbatim or with modifications and/or translated into another " "language. (Hereinafter, translation is included without limitation in " "the term \"modification\".) Each licensee is addressed as \"you\". " "

    Activities other than copying, distribution and modification are not " "covered by this License; they are outside its scope. The act of " "running the Program is not restricted, and the output from the Program " "is covered only if its contents constitute a work based on the " "Program (independent of having been made by running the Program). " "Whether that is true depends on what the Program does. " "

    1. You may copy and distribute verbatim copies of the Program's " "source code as you receive it, in any medium, provided that you " "conspicuously and appropriately publish on each copy an appropriate " "copyright notice and disclaimer of warranty; keep intact all the " "notices that refer to this License and to the absence of any warranty; " "and give any other recipients of the Program a copy of this License " "along with the Program. " "

    You may charge a fee for the physical act of transferring a copy, and " "you may at your option offer warranty protection in exchange for a fee. " "

    2. You may modify your copy or copies of the Program or any portion " "of it, thus forming a work based on the Program, and copy and " "distribute such modifications or work under the terms of Section 1 " "above, provided that you also meet all of these conditions: " "

    a. You must cause the modified files to carry prominent notices " "stating that you changed the files and the date of any change. " "

    b. You must cause any work that you distribute or publish, that in " "whole or in part contains or is derived from the Program or any " "part thereof, to be licensed as a whole at no charge to all third " "parties under the terms of this License. " "

    c. if the modified program normally reads commands interactively " "when run, you must cause it, when started running for such " "interactive use in the most ordinary way, to print or display an " "announcement including an appropriate copyright notice and a " "notice that there is no warranty (or else, saying that you provide " "a warranty) and that users may redistribute the program under " "these conditions, and telling the user how to view a copy of this " "License. (Exception: if the Program itself is interactive but " "does not normally print such an announcement, your work based on " "the Program is not required to print an announcement.) " "

    These requirements apply to the modified work as a whole. If " "identifiable sections of that work are not derived from the Program, " "and can be reasonably considered independent and separate works in " "themselves, then this License, and its terms, do not apply to those " "sections when you distribute them as separate works. But when you " "distribute the same sections as part of a whole which is a work based " "on the Program, the distribution of the whole must be on the terms of " "this License, whose permissions for other licensees extend to the " "entire whole, and thus to each and every part regardless of who wrote it. " "

    Thus, it is not the intent of this section to claim rights or contest " "your rights to work written entirely by you; rather, the intent is to " "exercise the right to control the distribution of derivative or " "collective works based on the Program. " "

    In addition, mere aggregation of another work not based on the Program " "with the Program (or with a work based on the Program) on a volume of " "a storage or distribution medium does not bring the other work under " "the scope of this License. " "

    3. You may copy and distribute the Program (or a work based on it, " "under Section 2) in object code or executable form under the terms of " "Sections 1 and 2 above provided that you also do one of the following: " "

    a. Accompany it with the complete corresponding machine-readable " "source code, which must be distributed under the terms of Sections " "1 and 2 above on a medium customarily used for software interchange; or, " "

    b. Accompany it with a written offer, valid for at least three " "years, to give any third party, for a charge no more than your " "cost of physically performing source distribution, a complete " "machine-readable copy of the corresponding source code, to be " "distributed under the terms of Sections 1 and 2 above on a medium " "customarily used for software interchange; or, " "

    c. Accompany it with the information you received as to the offer " "to distribute corresponding source code. (This alternative is " "allowed only for noncommercial distribution and only if you " "received the program in object code or executable form with such " "an offer, in accord with Subsection b above.) " "

    The source code for a work means the preferred form of the work for " "making modifications to it. For an executable work, complete source " "code means all the source code for all modules it contains, plus any " "associated interface definition files, plus the scripts used to " "control compilation and installation of the executable. However, as a " "special exception, the source code distributed need not include " "anything that is normally distributed (in either source or binary " "form) with the major components (compiler, kernel, and so on) of the " "operating system on which the executable runs, unless that component " "itself accompanies the executable. " "

    If distribution of executable or object code is made by offering " "access to copy from a designated place, then offering equivalent " "access to copy the source code from the same place counts as " "distribution of the source code, even though third parties are not " "compelled to copy the source along with the object code. " "

    4. You may not copy, modify, sublicense, or distribute the Program " "except as expressly provided under this License. Any attempt " "otherwise to copy, modify, sublicense or distribute the Program is " "void, and will automatically terminate your rights under this License. " "However, parties who have received copies, or rights, from you under " "this License will not have their licenses terminated so long as such " "parties remain in full compliance. " "

    5. You are not required to accept this License, since you have not " "signed it. However, nothing else grants you permission to modify or " "distribute the Program or its derivative works. These actions are " "prohibited by law if you do not accept this License. Therefore, by " "modifying or distributing the Program (or any work based on the " "Program), you indicate your acceptance of this License to do so, and " "all its terms and conditions for copying, distributing or modifying " "the Program or works based on it. " "

    6. Each time you redistribute the Program (or any work based on the " "Program), the recipient automatically receives a license from the " "original licensor to copy, distribute or modify the Program subject to " "these terms and conditions. You may not impose any further " "restrictions on the recipients' exercise of the rights granted herein. " "You are not responsible for enforcing compliance by third parties to " "this License. " "

    7. If, as a consequence of a court judgment or allegation of patent " "infringement or for any other reason (not limited to patent issues), " "conditions are imposed on you (whether by court order, agreement or " "otherwise) that contradict the conditions of this License, they do not " "excuse you from the conditions of this License. If you cannot " "distribute so as to satisfy simultaneously your obligations under this " "License and any other pertinent obligations, then as a consequence you " "may not distribute the Program at all. For example, if a patent " "license would not permit royalty-free redistribution of the Program by " "all those who receive copies directly or indirectly through you, then " "the only way you could satisfy both it and this License would be to " "refrain entirely from distribution of the Program. " "

    If any portion of this section is held invalid or unenforceable under " "any particular circumstance, the balance of the section is intended to " "apply and the section as a whole is intended to apply in other " "circumstances. " "

    It is not the purpose of this section to induce you to infringe any " "patents or other property right claims or to contest validity of any " "such claims; this section has the sole purpose of protecting the " "integrity of the free software distribution system, which is " "implemented by public license practices. Many people have made " "generous contributions to the wide range of software distributed " "through that system in reliance on consistent application of that " "system; it is up to the author/donor to decide if he or she is willing " "to distribute software through any other system and a licensee cannot " "impose that choice. " "

    This section is intended to make thoroughly clear what is believed to " "be a consequence of the rest of this License. " "

    8. If the distribution and/or use of the Program is restricted in " "certain countries either by patents or by copyrighted interfaces, the " "original copyright holder who places the Program under this License " "may add an explicit geographical distribution limitation excluding " "those countries, so that distribution is permitted only in or among " "countries not thus excluded. In such case, this License incorporates " "the limitation as if written in the body of this License. " "

    9. The Free Software Foundation may publish revised and/or new versions " "of the General Public License from time to time. Such new versions will " "be similar in spirit to the present version, but may differ in detail to " "address new problems or concerns. " "

    Each version is given a distinguishing version number. If the Program " "specifies a version number of this License which applies to it and \"any " "later version\", you have the option of following the terms and conditions " "either of that version or of any later version published by the Free " "Software Foundation. If the Program does not specify a version number of " "this License, you may choose any version ever published by the Free Software " "Foundation. " "

    10. If you wish to incorporate parts of the Program into other free " "programs whose distribution conditions are different, write to the author " "to ask for permission. For software which is copyrighted by the Free " "Software Foundation, write to the Free Software Foundation; we sometimes " "make exceptions for this. Our decision will be guided by the two goals " "of preserving the free status of all derivatives of our free software and " "of promoting the sharing and reuse of software generally. " "

    NO WARRANTY

    \n" "

    11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY " "FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN " "OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES " "PROVIDE THE PROGRAM \"AS IS\" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED " "OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF " "MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS " "TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE " "PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, " "REPAIR OR CORRECTION. " "

    IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING " "WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR " "REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, " "INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING " "OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED " "TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY " "YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER " "PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE " "POSSIBILITY OF SUCH DAMAGES. " "

    END OF TERMS AND CONDITIONS

    \n" "

    How to Apply These Terms to Your New Programs

    \n" "\n" "

    If you develop a new program, and you want it to be of the greatest\n" "possible use to the public, the best way to achieve this is to make it\n" "free software which everyone can redistribute and change under these terms.\n" "\n" "

    To do so, attach the following notices to the program. It is safest\n" "to attach them to the start of each source file to most effectively\n" "convey the exclusion of warranty; and each file should have at least\n" "the \"copyright\" line and a pointer to where the full notice is found.\n" "\n" "

    \n"
    "one line to give the program's name and an idea of what it does.\n"
    "Copyright (C) yyyy  name of author\n"
    "\n"
    "This program is free software; you can redistribute it and/or\n"
    "modify it under the terms of the GNU General Public License\n"
    "as published by the Free Software Foundation; either version 2\n"
    "of the License, or (at your option) any later version.\n"
    "\n"
    "This program is distributed in the hope that it will be useful,\n"
    "but WITHOUT ANY WARRANTY; without even the implied warranty of\n"
    "MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the\n"
    "GNU General Public License for more details.\n"
    "\n"
    "You should have received a copy of the GNU General Public License\n"
    "along with this program; if not, write to the Free Software\n"
    "Foundation, Inc., 59 Temple Place - Suite 330, Boston, MA  02111-1307, USA.\n"
    "
    \n" "\n" "

    Also add information on how to contact you by electronic and paper mail.\n" "\n" "

    If the program is interactive, make it output a short notice like this\n" "when it starts in an interactive mode:\n" "\n" "

    \n"
    "Gnomovision version 69, Copyright (C) year name of author\n"
    "Gnomovision comes with ABSOLUTELY NO WARRANTY; for details\n"
    "type `show w'.  This is free software, and you are welcome\n"
    "to redistribute it under certain conditions; type `show c' \n"
    "for details.\n"
    "
    \n" "\n" "

    The hypothetical commands `show w' and `show c' should show\n" "the appropriate parts of the General Public License. Of course, the\n" "commands you use may be called something other than `show w' and\n" "`show c'; they could even be mouse-clicks or menu items--whatever\n" "suits your program.\n" "\n" "

    You should also get your employer (if you work as a programmer) or your\n" "school, if any, to sign a \"copyright disclaimer\" for the program, if\n" "necessary. Here is a sample; alter the names:\n" "\n" "
