morituri is a CD ripper aiming for accuracy over speed.
Its features are modeled to compare with Exact Audio Copy on Windows.
FEATURES
--------
- support for MusicBrainz for metadata lookup
- support for AccurateRip verification
- detects sample read offset
- test and copy rip
REQUIREMENTS
------------
- cdparanoia, for the actual ripping
- cdrdao, for session, TOC, pregap, and ISRC extraction
- GStreamer, for encoding
- pycdio, for drive identification
KNOWN ISSUES
------------
- cdrdao read-toc does not always get pregaps right compared to EAC, still
under investigation
GOALS
-----
- quality over speed
- support one-command automatic ripping
- support offline ripping (doing metadata lookup and log rewriting later)
- separate the info/result about the rip from the metadata/file generation/...

To avoid confusion:
- cuefile is used for the CueFile object, which wraps/parses an existing .cue
file on disk
- tocfile: same
- toc: table of contents of a CD; instance of Table
test: single rip of kings of leon - only by the night
