BBQ-CDR is the Batch Burner with Queues, a set of Perl scripts to facilitate burning audio CD-Rs quickly and efficiently with minimal user-interaction. To achieve this, BBQ simultaneously burns and decompresses audio and allows CDs to be burned via WWW.
cdr is a CD ripper for Linux. It's a simple program with a no-frills console interface. It does one thing well -- the user interface -- and leaves the rest to other components with the same philosophy.
