Paradoxically enough, it does work as a standard GRASS module w/
G_parser interface (need libgis to query for the "GISBASE" path).  So,
it could result in listing the interface to itself, along with the
others...

However, if an xml file for each command was dumped to a directory a
priori, then I could work up a non-GRASS specific program to do various
things.  Perhaps that would be more useful?  

I just realized about an hour ago that G_usage_xml() (in
libes/gis/parser.c) and the corresponding DTD (in src/gui) don't have
any representation for the "key_desc" Option member, nor for the
"gisprompt" Option member.  Both should probably exist.  So, eventually
a client using this info could validate inputs like coordinate pairs
(key_desc = "x,y") and or prompt for certain mapset "files" (like
tcltkgrass and nviz do...).  I suppose both could be added as
optional attributes to the parameter element. Like:

<parameter name="map" type="string" required="yes" multiple="no"
 gisprompt="old,cell,raster">

or

<parameter name="coord" type="float" required="yes" multiple="yes"
keydesc="x,y">

Anyway...
