+unsf (converts SoundFont .sf2 files into GUS-type instrument patches)
+
+UnSF is a tool to convert SoundFont (sf2) files into GUS patches. libunsf
+is a library that is used by UnSF.
+
+Some reasons you might want to do such a thing are:
+
+ - Your MIDI player can use GUS patches but doesn't know how to read
+ soundfonts.
+
+ - You want a convenient way of substituting patches or reassigning
+ banks of instruments by editing GUS config files.
+
+ - You need to modify patches by changing amplitude, stripping
+ envelopes, or make other changes that can easily be done by attaching
+ options in config files.
+
+Note: the set of patches created by unsf will be quite a bit larger
+that the original .sf2 file. As an example, FluidR3_GM.sf2 (from
+fluid-soundfont) is a 142MB file, and it converts to almost 2GB of patches
+(size increased by a factor of 13.5).
