GPP is a general-purpose preprocessor with customizable syntax, suitable for a wide range of preprocessing tasks. Its independence from any programming language makes it much more versatile than cpp, while its syntax is lighter and more flexible than that of m4. The syntax is fully customizable, which makes it possible to process text files, HTML, or source code equally efficiently in a variety of languages.
kmamu is a shell script which installs X icons for xmame into a folder on your KDE1 or KDE2/3 desktop. (These icons can be downloaded from the homepage.) When installed, each icon has a long description name as provided by xmame -listgames, and when clicked it will launch xmame with the appropriate game. Although the install script is specific for KDE, the icons are stored in X pixmap format and can be used with any window manager.
sh-httpd is a shell script-based Web server that supports GET and HEAD methods, and a CGI 1.1 interface. It's not real fast, and it's probably not real secure, but it is really small. The Web server and it's configuration files are around 9,000 bytes total, and that's with comments and pretty whitespace. If you can run ash or bash, an inetd, and about 7 standard external commands on your system, you can have a Web server with CGI support. There's also a timeout counter that kills never-ending CGI programs, cleans up, and exits.
^txt2regex$ is a Regular Expression "wizard", written with bash2 builtins, that converts human sentences to regular expressions. With a simple interface, you just answer questions and build your own regexp for a large variety of programs, such as awk, ed, emacs, grep, Perl, PHP, procmail, Python, sed, and vim (there are more than 20 supported programs). As it is written in bash, no compilation is required.
smake is a highly portable 'make' program that makes commands up to date based on rules in Makefiles and on the timestamps of the related files. It implements a complete superset of the features of the classical POSIX/Unix make program. It warns about typical misuse of dynamic macros that prevent portability of makefiles. Its automake features allow you to run scripts to automatically create rules for unknown platforms.
The GNU Autoconf Archive is a collection of more than 450 macros for GNU Autoconf. They can be re-used without imposing any restrictions on the licensing of the generated configure script. In particular, it is possible to use them in configure scripts that are meant for non-free software.
Genrd is a bash shell script frontend to Robodoc and Robodoc-DB which greatly simplifies Robodoc's use with multiple files. Robodoc-DB (also included) is a version of Robodoc which has been modified to produce Docbook SGML. It generates source code documentation from almost any language (including PHP, C, HTML, and others), producing a variety of formats, including PDF, HTML, text, and RTF.
