Changelog for Abuse
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.
