Pipadoc extracts extracts special comments out of source files or plaintext files and let one define rules how to bring them into proper order. This is somewhat similar to Literate Programming, but it puts the emphasis back to the code, since the source is not extracted from a given "literate text", but the documentation is extracted from the source and then the structure of the generated documentation is defined by the programmer. Pipadoc is programming language and documentation system agnostic, all it requires is that the programming language has some kind of line or block comments in one can place doc statements. It provides a plugin system where one can extend functionality. Some plugins for asciidoc, index generation, and verbatim code sections are provided.
The Epeios MIDI to XML converter makes it possible to convert binary MIDI files to a format that allows them to be handled effectively with tools like CVS. If you put, using your favorite MIDI sequencer, the CVS '$Id$' tag (or other CVS tags) in the comment tag of the MIDI file, the changes made to this tag by CVS are propagated into the MIDI file.
