TkCVS is a cross-platform, Tcl/Tk-based GUI for the CVS and Subversion configuration management systems. It displays the status of the files in the current working directory, and provides buttons and menus to execute CVS, Subversion, or RCS commands on the selected files. The Log Browser displays a branch diagram of the revision history. The Module Browser extends CVS with facilities for a user-friendly listing of modules in the repository. TkDiff is included for browsing and merging your changes.
Flac-utils is a toolkit for managing FLAC files. Its primary usage is syncing metadata between sets of FLAC files. Flac-utils also provides a Python module called flac_compare that can be used separately. The utilitiy consist of three tools: flac-sync, which syncs a file tree of FLAC comments for files with the same audio-part; flac-diff, which compares two FLAC files' metadata information and shows the differences; and flac-add-picture, which adds album cover art to the files using Amazon.
