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. 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 Pro- gram 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. (Here- inafter, 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 copy- right 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 per- missions 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 deriva- tive 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 fol- lowing: a. Accompany it with the complete corresponding machine-readable source code, which must be dis- tributed 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 installa- tion 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 compo- nents (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 distri- bution 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 automati- cally 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' exer- cise 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 distribu- tion is permitted only in or among countries not thus excluded. In such case, this License incorpo- rates 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 dif- fer 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 condi- tions 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 CORREC- TION. 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.

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) 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 ``copy- right 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.

The Free Translation Project is a way to get maintainers of free software, translators, and users all together, so that free software will gradually become able to speak many languages. A few packages already provide translations for their messages. If you found this 'ABOUT-NLS' file inside a distribution, you may assume that the distributed package does use GNU 'gettext' internally, itself available at your nearest GNU archive site. But you do _not_ need to install GNU 'gettext' prior to configuring, installing or using this package with messages translated. Installers will find here some useful hints. These notes also explain how users should proceed for getting the programs to use the available translations. They tell how people wanting to contribute and work on translations can contact the appropriate team. 1.1 INSTALL Matters =================== Some packages are "localizable" when properly installed; the programs they contain can be made to speak your own native language. Most such packages use GNU 'gettext'. Other packages have their own ways to internationalization, predating GNU 'gettext'. By default, this package will be installed to allow translation of messages. It will automatically detect whether the system already provides the GNU 'gettext' functions. Installers may use special options at configuration time for changing the default behaviour. The command: ./configure --disable-nls will _totally_ disable translation of messages. When you already have GNU 'gettext' installed on your system and run configure without an option for your new package, 'configure' will probably detect the previously built and installed 'libintl' library and will decide to use it. If not, you may have to to use the '--with-libintl-prefix' option to tell 'configure' where to look for it. Internationalized packages usually have many 'po/LL.po' files, where LL gives an ISO 639 two-letter code identifying the language. Unless translations have been forbidden at 'configure' time by using the '--disable-nls' switch, all available translations are installed together with the package. However, the environment variable 'LINGUAS' may be set, prior to configuration, to limit the installed set. 'LINGUAS' should then contain a space separated list of two-letter codes, stating which languages are allowed. 1.2 Using This Package ====================== As a user, if your language has been installed for this package, you only have to set the 'LANG' environment variable to the appropriate 'LL_CC' combination. If you happen to have the 'LC_ALL' or some other 'LC_xxx' environment variables set, you should unset them before setting 'LANG', otherwise the setting of 'LANG' will not have the desired effect. Here 'LL' is an ISO 639 two-letter language code, and 'CC' is an ISO 3166 two-letter country code. For example, let's suppose that you speak German and live in Germany. At the shell prompt, merely execute 'setenv LANG de_DE' (in 'csh'), 'export LANG; LANG=de_DE' (in 'sh') or 'export LANG=de_DE' (in 'bash'). This can be done from your '.login' or '.profile' file, once and for all. You might think that the country code specification is redundant. But in fact, some languages have dialects in different countries. For example, 'de_AT' is used for Austria, and 'pt_BR' for Brazil. The country code serves to distinguish the dialects. The locale naming convention of 'LL_CC', with 'LL' denoting the language and 'CC' denoting the country, is the one use on systems based on GNU libc. On other systems, some variations of this scheme are used, such as 'LL' or 'LL_CC.ENCODING'. You can get the list of locales supported by your system for your language by running the command 'locale -a | grep '^LL''. Not all programs have translations for all languages. By default, an English message is shown in place of a nonexistent translation. If you understand other languages, you can set up a priority list of languages. This is done through a different environment variable, called 'LANGUAGE'. GNU 'gettext' gives preference to 'LANGUAGE' over 'LANG' for the purpose of message handling, but you still need to have 'LANG' set to the primary language; this is required by other parts of the system libraries. For example, some Swedish users who would rather read translations in German than English for when Swedish is not available, set 'LANGUAGE' to 'sv:de' while leaving 'LANG' to 'sv_SE'. Special advice for Norwegian users: The language code for Norwegian bokma*l changed from 'no' to 'nb' recently (in 2003). During the transition period, while some message catalogs for this language are installed under 'nb' and some older ones under 'no', it's recommended for Norwegian users to set 'LANGUAGE' to 'nb:no' so that both newer and older translations are used. In the 'LANGUAGE' environment variable, but not in the 'LANG' environment variable, 'LL_CC' combinations can be abbreviated as 'LL' to denote the language's main dialect. For example, 'de' is equivalent to 'de_DE' (German as spoken in Germany), and 'pt' to 'pt_PT' (Portuguese as spoken in Portugal) in this context. 1.3 Translating Teams ===================== For the Free Translation Project to be a success, we need interested people who like their own language and write it well, and who are also able to synergize with other translators speaking the same language. Each translation team has its own mailing list. The up-to-date list of teams can be found at the Free Translation Project's homepage, 'http://translationproject.org/', in the "Teams" area. If you'd like to volunteer to _work_ at translating messages, you should become a member of the translating team for your own language. The subscribing address is _not_ the same as the list itself, it has '-request' appended. For example, speakers of Swedish can send a message to 'sv-request@li.org', having this message body: subscribe Keep in mind that team members are expected to participate _actively_ in translations, or at solving translational difficulties, rather than merely lurking around. If your team does not exist yet and you want to start one, or if you are unsure about what to do or how to get started, please write to 'coordinator@translationproject.org' to reach the coordinator for all translator teams. The English team is special. It works at improving and uniformizing the terminology in use. Proven linguistic skills are praised more than programming skills, here. 1.4 Available Packages ====================== Languages are not equally supported in all packages. The following matrix shows the current state of internationalization, as of Jun 2014. The matrix shows, in regard of each package, for which languages PO files have been submitted to translation coordination, with a translation percentage of at least 50%.

preceding matrix are higher than the number of visible blocks let us expect. This is because a few extra PO files are used for implementing regional variants of languages, or language dialects. For a PO file in the matrix above to be effective, the package to which it applies should also have been internationalized and distributed as such by its maintainer. There might be an observable lag between the mere existence a PO file and its wide availability in a distribution. If Jun 2014 seems to be old, you may fetch a more recent copy of this 'ABOUT-NLS' file on most GNU archive sites. The most up-to-date matrix with full percentage details can be found at 'http://translationproject.org/extra/matrix.html'. 1.5 Using 'gettext' in new packages =================================== If you are writing a freely available program and want to internationalize it you are welcome to use GNU 'gettext' in your package. Of course you have to respect the GNU Lesser General Public License which covers the use of the GNU 'gettext' library. This means in particular that even non-free programs can use 'libintl' as a shared library, whereas only free software can use 'libintl' as a static library or use modified versions of 'libintl'. Once the sources are changed appropriately and the setup can handle the use of 'gettext' the only thing missing are the translations. The Free Translation Project is also available for packages which are not developed inside the GNU project. Therefore the information given above applies also for every other Free Software Project. Contact 'coordinator@translationproject.org' to make the '.pot' files available to the translation teams. dfcgen-gtk-0.5/doc/0000755000175100001440000000000013733651721011142 500000000000000dfcgen-gtk-0.5/doc/dfcgen.sty0000664000175100001440000000202013707736412013047 00000000000000\NeedsTeXFormat{LaTeX2e} \ProvidesPackage{dfcgen} \RequirePackage{amsmath} %% Jacobian elliptic functions \DeclareMathOperator{\jam}{am} \DeclareMathOperator{\jdelta}{\varDelta} % delta-amplitude \DeclareMathOperator{\jsn}{sn} \DeclareMathOperator{\jcn}{cn} \DeclareMathOperator{\jdn}{dn} \DeclareMathOperator{\jcd}{cd} \DeclareMathOperator{\jdc}{dc} \DeclareMathOperator{\jsc}{sc} \DeclareMathOperator{\jnc}{nc} \DeclareMathOperator{\jds}{ds} \DeclareMathOperator{\jcs}{cs} \DeclareMathOperator{\jsd}{sd} \DeclareMathOperator{\jns}{ns} \DeclareMathOperator{\jnd}{nd} \DeclareMathOperator{\arsinh}{arsinh} \DeclareMathOperator{\arcosh}{arcosh} \DeclareMathOperator{\artanh}{artanh} \DeclareMathOperator{\chebyT}{T} % Chebyshev function of first kind \DeclareMathOperator{\si}{si} % Sinus Cardinalis \DeclareMathOperator{\Si}{Si} % Sine Integral \DeclareMathOperator{\imop}{Im} % Imaginary part of complex number (Im{} operator) \DeclareMathOperator{\reop}{Re} % real part of complex number (Re{} operator) dfcgen-gtk-0.5/doc/Doxyfile0000644000175100001440000031764013645011561012575 00000000000000# Doxyfile 1.8.11 # This file describes the settings to be used by the documentation system # doxygen (www.doxygen.org) for a project. # # All text after a double hash (##) is considered a comment and is placed in # front of the TAG it is preceding. # # All text after a single hash (#) is considered a comment and will be ignored. # The format is: # TAG = value [value, ...] # For lists, items can also be appended using: # TAG += value [value, ...] # Values that contain spaces should be placed between quotes (\" \"). #--------------------------------------------------------------------------- # Project related configuration options #--------------------------------------------------------------------------- # This tag specifies the encoding used for all characters in the config file # that follow.

See http://www.gnu.org/software/libiconv # for the list of possible encodings. # The default value is: UTF-8. DOXYFILE_ENCODING = UTF-8 # The PROJECT_NAME tag is a single word (or a sequence of words surrounded by # double-quotes, unless you are using Doxywizard) that should identify the # project for which the documentation is generated.

The maximum height of the logo should not exceed 55 # pixels and the maximum width should not exceed 200 pixels. Doxygen will copy # the logo to the output directory. PROJECT_LOGO = # The OUTPUT_DIRECTORY tag is used to specify the (relative or absolute) path # into which the generated documentation will be written.

OUTPUT_DIRECTORY = . # If the CREATE_SUBDIRS tag is set to YES then doxygen will create 4096 sub- # directories (in 2 levels) under the output directory of each output format and # will distribute the generated files over these directories.

CREATE_SUBDIRS = NO # If the ALLOW_UNICODE_NAMES tag is set to YES, doxygen will allow non-ASCII # characters to appear in the names of generated files.

REPEAT_BRIEF = YES # This tag implements a quasi-intelligent brief description abbreviator that is # used to form the text in various listings.

STRIP_FROM_PATH = # The STRIP_FROM_INC_PATH tag can be used to strip a user-defined part of the # path mentioned in the documentation of a class, which tells the reader which # header file to include in order to use a class.
