ripx is a script designed to make ripping CDs as easy as possible. It features CDDB lookup, ID3 tag editing prior to ripping, playlist file generation, album directory creation, and generally a nicer interface than many similar tools. By default, ripx uses cdparanoia to extract audio from CDs and lame to encode the audio to MP3 format at the quality of your choice. If you wish to use alternative applications for extraction or encoding, modifying ripx to handle these should be fairly painless.
