-- original readme --

ptplay.library is a library to play protracker modules. It is based on
work of Ronald Hof, Timm Mueller and Per Johansson with my own additions:

  - shared library
  - support for SoundTracker modules

However SoundTracker support is unfinished but since there are better
MOD player libraries for MorphOS I havent got motivation to finish it.
I also started working on SoundFX player but since Mahendra Tallur
created geronto.library my work is done ;)

This source code has been rotting on my HD about two years now so I think
it is about time to release it. AmigaOS users might find it interesting still.
