This makes it suitable to create R scripts via the so\-called shebang '#!/' line. The optional \fBR arguments\fR are stored in the \fBR\fR vector \fBargv\fR. .SH OPTIONS .TP \fB\-h\fR, \fB\-\-help\fR Display a short help list. .TP \fB\-\-usage\fR Give a short usage message. .TP \fB\-V\fR, \fB\-\-version\fR Show the version number. .TP \fB\-v\fR, \fB\-\-vanilla\fR Pass the '\-\-vanilla' option to R. .TP \fB\-p\fR, \fB\-\-verbose\fR Print the value of expressions to the console. .TP \fB\-l\fR, \fB\-\-packages\fR list Load the R packages from the comma\-separated 'list'. .TP \fB\-t\fR, \fB\-\-rtemp\fR Use a per-session temporary directory as R does. .TP \fB\-q\fR, \fB\-\-quick\fR Skip autoload (i.e. delayed assign) of default libraries. .TP \fB\-i\fR, \fB\-\-interactive\fR Force 'interactive()' to evaluate to TRUE, whereas the default is FALSE. .TP \fB\-e\fR, \fB\-\-eval expr\fR Evaluate 'expr' in R. .PP .SH USAGE \fBr\fR can be used in command-line 'pipes' as well as in 'shebang'-style scripts. .SH EXAMPLES Piping \fBR\fP commands: echo 'cat(pi^2,"\\n")' | r Equivalently, \fBR\fP commands can be given on the command-line: r -e 'cat(pi^2, "\\n")' Alternatively, commands can be stored in a file, which in turn might use \fBR\fP command 'readLines' to process stdin input: $ cat examples/fsizes.r fsizes <- as.integer(readLines()) print(summary(fsizes)) stem(fsizes) which can be evaluated by \fBr\fP with the following command: ls -l /boot | awk '!/^total/ {print $5}' | r examples/fsizes.r The script file may contain a "shebang" line: $ cat examples/install.r #!/usr/bin/env r # a simple example to install one or more packages if (is.null(argv) | length(argv)<1) { cat("Usage: installr.r pkg1 [pkg2 pkg3 ...]\n") q() } repos <- "http://cran.us.r-project.org" lib.loc <- "/usr/local/lib/R/site-library" install.packages(argv, lib.loc, repos, dependencies=TRUE) and if it is executable, it can be called as: examples/install.r "TeachingDemos" See the examples directory in the sources for more. .SH NOTE The executable program is called \fBr\fR, but the project is called \fBlittler\fR to avoid confusion with the real \fBGNU R\fR. .SH SEE ALSO The \fBGNU R\fR language is documented extensively at the R website (http://www.r-project.org) and in several manuals available in html, info and pdf. .SH AUTHORS Jeffrey Horner .

Sometimes, however, simple scripts are desired. While GNU R can be used in batch mode, and while so-called 'here' documents can be crafted, a long-standing need for a scripting front-end has often been expressed by the R Community. littler (pronounced 'little R' and written 'r') aims to fill this need. It can be used directly on the command-line just like, say, bc(1): $ echo 'cat(pi^2,"\n")' | r 9.869604 Equivalently, commands that are to be evaluated can be given on the command-line $ r -e 'cat(pi^2, "\n")' 9.869604 But unlike bc(1), GNU R has a vast number of statistical functions. For example, we can quickly compute a summary() and show a stem-and-leaf plot for file sizes in a given directory via $ ls -l /boot | awk '!/^total/ {print $5}' | \ r -e 'fsizes <- as.integer(readLines()); print(summary(fsizes)); stem(fsizes)' Min. 1st Qu. Median Mean 3rd Qu. Max. 13 512 110100 486900 768400 4735000 Loading required package: grDevices The decimal point is 6 digit(s) to the right of the | 0 | 00000000000000000011112223 0 | 5557778899 1 | 112233 1 | 5 2 | 2 | 3 | 3 | 4 | 4 | 7 And, last but not least, this (somewhat unwieldy) expression can be stored in a helper script: $ cat examples/fsizes.r #!/usr/bin/env r fsizes <- as.integer(readLines()) print(summary(fsizes)) stem(fsizes) (where calling /usr/bin/env is a trick from Python which allows one to forget whether r is installed in /usr/bin/r, /usr/local/bin/r, ~/bin/r, ...) A few examples are provided in the source directories examples/ and tests/. Where ? ======= littler can either be downloaded from either of http://biostat.mc.vanderbilt.edu/LittleR http://dirk.eddelbuettel.com/code/littler.html accessed via SVN using svn checkout http://littler.googlecode.com/svn/trunk/ littler or (soon !) be gotten from Debian mirrors via $ apt-get install littler littler is known to build and run on Linux and OS X.

In other projects, it is set to # `$srcdir', `$srcdir/..', or `$srcdir/../..'. # # Of course, Automake must honor this variable whenever it calls a # tool from the auxiliary directory. The problem is that $srcdir (and # therefore $ac_aux_dir as well) can be either absolute or relative, # depending on how configure is run. This is pretty annoying, since # it makes $ac_aux_dir quite unusable in subdirectories: in the top # source directory, any form will work fine, but in subdirectories a # relative path needs to be adjusted first. # # $ac_aux_dir/missing # fails when called from a subdirectory if $ac_aux_dir is relative # $top_srcdir/$ac_aux_dir/missing # fails if $ac_aux_dir is absolute, # fails when called from a subdirectory in a VPATH build with # a relative $ac_aux_dir # # The reason of the latter failure is that $top_srcdir and $ac_aux_dir # are both prefixed by $srcdir. In an in-source build this is usually # harmless because $srcdir is `.', but things will broke when you # start a VPATH build or use an absolute $srcdir. # # So we could use something similar to $top_srcdir/$ac_aux_dir/missing, # iff we strip the leading $srcdir from $ac_aux_dir. That would be: # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"` # and then we would define $MISSING as # MISSING="\${SHELL} $am_aux_dir/missing" # This will work as long as MISSING is not called from configure, because # unfortunately $(top_srcdir) has no meaning in configure. # However there are other variables, like CC, which are often used in # configure, and could therefore not use this "fixed" $ac_aux_dir. # # Another solution, used here, is to always expand $ac_aux_dir to an # absolute PATH.

Please see the file 'INSTALL' for installation tips. II. Implementation ==================== littler, a C-language program named 'r', is an alternative front end to GNU R for '#!' (hashbang) scripting (see "Embedding R under Unix-alikes" in the "Writing R Extensions" manual from either http://www.r-project.org/, or your R installations / sources). With it's simpler command-line argument set geared toward scripting, littler allows users to create R scripts and popular "one-liners" using the command-line flag --eval. To do this, littler hard-codes certain bits of R's installation and environment using the first R program found in the user's path. For instance, if you installed R in both /usr/bin and /usr/local/bin, and your PATH variable references /usr/bin first, then littler will configure itself with /usr/bin/R. II.1 R_HOME ----------- The R_HOME environment variable is written to the header file littler.h so that it can be hard-coded into the r binary. Note that it overrides the user's own R_HOME environment variable when r is executed. II.2 R_DEFAULT_PACKAGES ----------------------- To decrease r's startup time, it sets the environment variable R_DEFAULT_PACKAGES to NULL and then autoloads all of the default package methods. This is done by inspecting the R user option 'defaultPackages' and emitting c code to be statically compiled into r. See autoloads.R for more info. II.3 LD_LIBRARY_PATH -------------------- To eliminate the dependency on the LD_LIBRARY_PATH environment variable, at least on linux, r looks to the file R_HOME/etc/ldpaths to set the -rpath linker option (see ldpaths.R for more info). Unfortunately this linker flag is not supported on Mac OS X, so r still depends on DYLD_LIBRARY_PATH. One caveat of working directly with LD_LIBRARY_PATH is that if one ever alters or updates R_HOME/etc/ldpaths (e.g. by running 'R CMD javareconf'), this will not be reflected in r. Thus, a re-compilation of r is necessary. II.4 Last but not least ----------------------- Upon exit no cleanup is done and .Last() is not run. This behavior is more suitable for a scripting environment as opposed to an interactive one. III. (In-) Frequently asked questions ====================================== III.1 Why the name 'littler' ? ------------------------------ We wanted something short, sweet and with sufficient reference to R without trampling over R. The 'little' part implies two things: 1) that the program name is the lower case 'r', and 2) that 'r' provides something less than GNU R, mainly the language interpreter without the R environment. 'littler' is meant to run in an automated, i.e scripted, fashion with little interaction from the user. We also like 'r' in /usr/local/bin/r, /usr/bin/r or on the command-line as it saves keystrokes, and does not harm the Shift key as much. Lastly, you will find a little r in both Jeffrey and Dirk :-) III.2. Wasn't there once a 'rinterp' as well ? --------------------------------------------- There was, but we think littler is cuter. See the previous question. III.3 I run a script through 'littler' but nothing shows. What's up? ----------------------------------------------------------------- Add the --verbose flag (or its -p short version). This will print out many relevant expressions, similar to GNU R. However, it won't print the value of expressions like for loops, if/else, or expressions within function calls. In that case you probably need to wrap a print() or cat() around what you want to show. III.4 Data sets are lost! ------------------------- Actually, they aren't. But because 'littler' optimises the startup, they are never loaded. Just add library(datasets) to your script. We have changed this behaviour in release 0.1.0, and datasets are now loaded on startup. III.5 It doesn't build and complains about 'R_SignalHandlers undeclared' ------------------------------------------------------------------------ You need to upgrade to R 2.3.1 or newer. Our configure ought to check for a minimal R versions and currently does not. III.6 The r binary name clashes with my R binary. -------------------------------------------------- Use the configure flag --program-prefix or --program-suffix to transform the binary name. For instance, if you would like the binary name to be 'rsp' run configure like this: ./configure --program-suffix=sp and if you'd rather have a prefix to the binary, run: ./configure --program-prefix=little which will name the binary 'littler'. The binary, as well as the manual page, are renamed when 'make install' is run. Should you need it, 'make uninstall' will also remember this setting. III.7 Typing r repeats the last command. ----------------------------------------- You must be a zsh user -- 'r' is a builtin command, so to prefer to littler, you will have to either use an explicit path (/usr/bin/r), create an alias under a different name, and install littler using a suffix or prefix as describe in III.6. III.8 What about Rscript? -------------------------- Good question. Starting with release 2.5.0, R itself will now contain something remarkably similar to littler: Rscript, an alternative front end to R for use in '#!' scripts. Time will tell which features differentiate the two, and which interface proves more useful to the R community. For now, we are simply thrilled to see functionality that we and others deemed important -- yet was missing from R itself -- added to the core R distribution. As they say, 'Imitation is the sincerest form of flattery'. Still, it would have been nice if Rscript had given credit to littler. Here's a look at the most visibly distinguishing feature of each front end: how arguments are passed to a script. Below are two 'hello world' scripts that print out their arguments, one implemented in Rscript and the other littler: Rscript ------- #! /path/to/Rscript args <- commandArgs() args <- args[-(1:match("--args", args)] cat('hello world! ', args,"\n") ------- littler ------- #! /path/to/r cat('hello world! ', argv,"\n") ------- Rscript passes all script arguments to R as additional elements to the vector returned from commandArgs(). Thus, the script must use the negative indexing method above to get the script argument into it's own variable. littler provides convenience by assigning the script arguments to an "argv" vector and placing that into the global environemt, a convention followed by other popular scripting languages. littler also tends to start faster as it doesn't need to exec() the main R process due to its embedding of R. III.9 What about getopt-style command-line parsing? ---------------------------------------------------- Great question! This was asked for a few times. Luckily, Allen Day came forward and wrote getopt (now on CRAN), initially for Rscript. Moreover, he also agreed to add a two-line patch for seamless littler support. See the getopt examples and documentation at http://cran.r-project.org/web/packages/getopt/index.html for usage -- it is really straightforward. III.10 What about temporary files and directories? --------------------------------------------------- If nothing else is specified, r defaults to /tmp after having checked the environment variables TMPDIR, TMP and TEMP. Since version 0.1.2, you can also provide the --rtemp option (or its short form -t) to let r behave like R with a unique per-session directory that gets removed at exit: $ r -tpe 'tempdir()' [1] "/tmp/RtmpSbNQBj" $ ls /tmp/RtmpSbNQBj ls: cannot access /tmp/RtmpSbNQBj: No such file or directory $ showing that the temporary directory is created and provided while r is running, but removed after r has finished. III.11 What about 'shebang' starts and command-line options? ------------------------------------------------------------- The usual operating systems can parse the so-called 'shebang' line, ie the first line of scripts that starts with the '#!' characters and the path to the executable --- and as much as one argument. That means we can provide short option arguments together in one string as in #!/usr/bin/r -pt which enables 'verbose printing' and 'R-alike per-session temp. directories'. What are typically not supported are multiple tokens (as used for an option and its argument, or multiple options). This also means that in the #!/usr/bin/env r case we cannot supply further arguments to r. IV Feedback ============== Comments are welcome, as are are suggestions, bug fixes, or patches. - Jeffrey Horner - Dirk Eddelbuettel littler-0.1.5/INSTALL0000644000175000017500000000504010655352643011156 00000000000000 1. Installation from distributed sources ======================================== 1.1 Requirements ---------------- GNU R has to be installed in a shared-library configuration. This is not the default, so you may have to rebuild R. If in doubt, look for a file 'libR.so' which should be in the lib/ directory of your R installtions, i.e. in /usr/local/lib/R/libR.so or /usr/lib/R/libR.so If R is not compiled with a shared library, you can rebuild from source with the following miminal recipe: # For GNU R, not littler ./configure --enable-R-shlib make make install See the R manuals for details. Linux and OS X are known to be supported at this point. In all likelihood, the requirement of shared libary precludes installation of littler on Windoze. 1.2 Basic Steps --------------- The minimal recipe for installation should apply, i.e. start by $ ./configure which will find the first path to R in your environment variable PATH. If you want the binary to be installation with a name other than 'r' (which is a good idea on case-insensitive systems like OS X), then you can set either --program-suffix or --program-prefix as in ./configure --program-suffix=sp # creates rsp and ./configure --program-prefix=little # creates littler If there's another R installation you want to use, then you'll have to readjust the PATH. For example: $ PATH=~/R-trunk/bin:$PATH ./configure Then $ make should build the 'r' binary, and $ sudo make install should install it, as well as the manual page. 2. Installation from SVN ======================== 2.1 Requirements ---------------- As above, but you will also need autoconf, aclocal, and of course svn itself. 2.2 SVN checkout ---------------- Anonymous checkout is available via $ svn checkout http://littler.googlecode.com/svn/trunk/ littler 2.3 Build preparation --------------------- You can simply run the catch-all script 'bootstrap': $ bootstrap which includes the steps from 1.2 above and produces a new executable. If you want to set configure options, you can do so too after an initial 'bootstrap' call. 3. Binary Installation ====================== 3.1 Debian ---------- Calling $ sudo apt-get install littler is all it takes if your sources.list file points to testing or unstable. 4. Feedback =========== Is encouraged ;-) - Jeffrey Horner - Dirk Eddelbuettel littler-0.1.5/COPYING0000644000175000017500000004311010655352643011160 00000000000000 GNU GENERAL PUBLIC LICENSE Version 2, June 1991 Copyright (C) 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 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. littler-0.1.5/config.h.in0000644000175000017500000000404311635130174012142 00000000000000/* config.h.in.
