From the web site:crip is a terminal-based ripper/encoder/tagger tool for creating Ogg Vorbis/FLAC/MP3 files under UNIX/Linux. It is well-suited for someone seeking to make a lot of files from CDs and have them all properly labeled and professional-quality. One thing to note is that the author of this free package has removed MP3 support, and limits you to Ogg Vorbis or FLAC for encoding.

Version 3.4 is shipping as of April, 2003.
