musicbrainz2sqlite is a Perl script that converts the MusicBrainz data
available http://ftp.musicbrainz.org/pub/musicbrainz/data/fullexport/
from the MusicBrainz web site into a SQLite database. Usage:

  % perl musicbrainz2sqlite.pl /path/to/mbdump musicbrainz.sqlite

Note that it does not create indices other than for primary keys; use
http://github.com/metabrainz/musicbrainz-server/blob/master/admin/sql/
CreateIndexes.sql for that.
