cygbuild is a porting tool for making Cygwin net releases. It helps Cygwin source and binary package maintainers to configure, build, strip, produce diffs, and generate Cygwin specific files.

Dim is a utility to help you track the changes of items (sets composed of multiple files). It provides commands to handle the complete lifecycle of version control operations: create a library, register users (code authors), create items, save local versions, branch, clone, export, import, remove, merge, archive, replicate library content over the network or the filesystem, and access the full history and browse differences at the library, item, file, line, or word level. Dim is a single self-documented POSIX shell script. It just uses standard Unix utilities like awk, diff, tar, and openssl.
Plait (pronounced "play") is a command-line jukebox and music player front end. It understands brief, easy to type queries that pick a single song, mix queries that combine works from multiple artists, and stream queries that find Shoutcast radio streams. A variety of filters are available to pick just the music you want to hear. In order to actually play the music it finds, Plait automatically hands off a playlist to one of the supported music players, or creates a playlist that you can manually load.
