Perthon converts Python source code to human- readable Perl 5.x source code. It makes use of Damian Conway's Parse::RecDescent for parsing, and aims to reimplement the Python language as specified in the Python Reference Manual and BNF grammar. Perthon is similar to Jython (www.jython.org), which reimplements Python on the JVM, except that Perthon works at the source code (not byte code) level. Perthon does the reverse of Bridgekeeper (http://www.crazy-compilers.com/bridgekeeper/), which attempts to solve the (much harder) problem of Perl-to-Python source code machine translation.
TapeChanger::MTX is a module to manipulate a tape library using the 'mtx' tape library program. It is meant to work with a simple shell/Perl script to load and unload tapes as appropriate, and to provide an interface for more complicated programs to do the same. It comes with a few basic scripts to use much of the functionality of the module.
PostScript::CDCover generates a Postscript program that prints a CD cover and backlabel, with contents displayed as a tree of directories and files. The module ships with a stand-alone, ready-to-use script, pscdcover, that takes the directory tree of a CD-ROM as input and generates a cover from it. The output can be directly fed to a PostScript printer, but it is designed to be easily editable (should one wish to remove unwanted directory entries, for example).
