 Hi,

 the wx module auto-gen GUI dialogs do not report the contents of
 opt->key_desc, so correct usage of the module options are hard to figure
 out without carefully studying the help page.

 v.mkgrid is a good example.
 {{{
 Usage:
  v.mkgrid [-pq] map=name grid=rows,columns [position=string]
    [coor=x,y] [box=width,height] [angle=value] [breaks=value]
 }}}

 the wx module GUI for it just asks for an int for grid= and box=, and a
 float for coor=. Little way to know you need a comma separated list, and
 it's even worse if the input is like x0,y0,x1,y1 and you don't know the
 order (an even worse than that example of this can be found in
 r.transect).

 The tcl/tk GUIs are a better, but still a bit murky.

 The --interface-description item for this is <keydesc>.

 entering this as a "defect" as v.mkgrid, r.transect, et al are at first
 unusable without this part of the usage definition.


 thanks,
 Hamish
