All levels and artwork are now part of the Abuse source. It is a merge
of abuse-lib, the original shareware version of the game (released into
the public domain except for the sound effects), abuse-frabs, the result
of a community effort to create free Abuse levels, abuse-data, a full
registered game dataset and abuse-mac, the Mac version developed by
Bungie.

Licensing terms for the data are still unclear but are being sorted out.
Jonathan Clark and Dave Taylor, the original Abuse authors, allowed the
full dataset to be freely redistributed with Abuse-SDL. Same with Bobby
Prince, the sound samples author. However Bobby did not allow
modification of the samples.
