It's a CD archive, with descriptions of all known music CDs
(FreeDB/expd).

You guessed it ;-)

Later, when I've ported the zip support. There are a lot of things to
explore, like the actual contents of time stamps and other OS specific
fields in the file descriptors. The current version is written for
Delphi and Windows, a port to FPC and other OS or machines will require
some adaptations; this is where somebody could jump in...

Hmm, the ~4 core units (90 KB) should be sufficiently stable for an FPC
and Linux port, if somebody is interested in such stuff. The
documentation (9 KB HTML) is not up to date, my code is intended to be
self-explanatory ;-)

Another thing is the grid control for a GUI (~50 KB), based on
TCustomGrid...
