Makescan generates a complete Makefile, parsing source files and headers. It does simple deductions on source file names to be included in the build list, resolves header dependencies, and allows the user to fine-tune several Makefile flags. It is useful for fast generation/updating of Makefiles in small and not-so-small C/C++ projects, and works with the GNU make processor.
RIG (Random Identity Generator) is a free replacement for a shareware program out there called 'fake'. It generates random, yet real-looking, personal data. It is useful if you need to feed a name to a Web site, BBS, or real person, and are too lazy to think of one yourself. Also, if the Web site/BBS/person you are giving the information to tries to crosscheck the city, state, zip, or area code, it will check out.
Grlib is an implementation of generative grammars and turtle graphics. The grammars (Lindenmayer systems) are used to produce descriptions of three dimensional objects, and the turtle is used to display them (i.e., generate images in several forms, such as bitmap, PostScript, or OpenGL).
