+libmodplug v0.7 - A library for decoding MOD-like music formats.
+ Based on the ModPlug sound engine by Olivier Lapicque <olivierl@jps.net>
+ Ported to Unix by Kenton Varda <temporal@gauge3d.org>
+ Additional modifications by Markus Fick <marf@gmx.net> and
+    Adam Goode <adam@evdebs.org>
+ Placed in the public domain in October, 2001
+
+
+All the documentation needed can be found in the comments in modplug.h.
+This library should be perfectly accessible from C, although it is written
+in C++.  Just #include <modplug.h> to use it, and link against
+libmodplug.so.
+
+This library has been known to compile fine in Windows using MinGW32 (A
+GCC-based compiler).  Windows is not yet officially supported, however.
+(With about half an hour of hacking, any decent programmer should be able
+to convince WinAmp to play mods using this library. ;) )
+
+I need a maintainer for this.  I have too many other projects I am working
+on, and ModPlug has dropped low on the list.  If you would like to be the
+new maintainer, please e-mail me at <temporal@gauge3d.org> and tell me why
+you think you would be the right person for the job.  :)
