Dateutils are a bunch of tools that revolve around fiddling with dates and times in the command line, with a strong focus on use cases that arise when dealing with large amounts of financial data. Their target market is shell scripts that need date calculations or calendar conversions, and as such they are highly pipe-able and modeled after their well-known cousins (e.g. dtest vs. test, or dgrep vs. grep).
LongoMatch is a sports video analysis tool for coaches to assist them in making game video analysis. You can tag the most important plays of the game and group them by categories to study each detail of the game strategy. A list with all the tagged plays lets you review them with a simple click, even in slow motion. The timeline gives a quick overview of the game and lets you adjust the lead and lag time of each play frame by frame. LongoMatch has support for playlists, an easy way to create presentations with plays from different games. You can create new videos with your favorite plays using the video editing feature.
wv2ogg is a tool that uses wvunpack, oggenc, and vorbiscomment to encode wavpack files to Ogg Vorbis files. The quality setting that will be used for encoding the Vorbis files can be set when running wv2ogg. It will also transfer all tags and replaygain information from the wavpack files to the Ogg Vorbis files by default. wv2ogg was written because no other software that would do this existed for Linux.
dudl is a collection of tools to grab, encode, and rename MP3 files, archive them, and maintain a database of all files. On top of this runs the dudld Jukebox daemon that plays your files through gstreamer. dudld's strengths are the powerful tag based filters, the capability to cope with very large collections, and the network protocol to control its operation. There is a full featured command-line client, a minimalistic GTK client, and a lirc client. Writing new clients should be easy with the supplied client libraries.
