[GRASS-dev] changing data for parser

[Michael Barton]

menuform.py uses the xml text generated by ³<command>
‹interface-description² to create the autogenerated dialogs. This dates to
2001. 

I was just reminded in a recent post to the grass developer list that there
is a richer interface description output called by ³<command> --tcltk². This
has been developed over the past year or so. I give an example below (part
of the output from ³d.vect ‹tcltk²). We might want to consider switching the
autogenerated panels to be created by the ‹tcltk code.

Besides being a richer set of descriptions (includes prompt for notebook
tabs and color picking dialogs), it looks easier to parse than the
‹interface description xml. It would also mean that we would not need sax.
