Schism Tracker is a music editor that aims to match the look and feel
of Impulse Tracker as closely as possible. The player code is based
on Modplug, so it supports a wide variety of module formats. Currently,
Schism Tracker is supported for Linux x86 systems, Mac OS X, and Windows.
Additional operating systems it is known to work on include FreeBSD,
Haiku/Zeta/BeOS, and AmigaOS/MorphOS; however, these OSes are not officially
supported. It is fairly portable, however, and will probably build
on any modern *nix-based system with little to no extra effort.
