With the new work by Cedric Shock, the updated GIS Manager is in
considerable flux. I think that most of it will be ironed out soon. If we
don't count things to be fixed, I'd like to at least do the following:

Make a new GRASS start up.
Make sure that the GEM (GRASS extension manager) is working with the new
system.

If there is time before a feature freeze, a couple of important items that
need to be done include:

develop a non-xterm version of v.digit
develop a non-xterm version of i.points/v.points
develop a TclTk module that reads v.label files and places labels on the
screen in nice PS text (I think fairly easy).
There may be other things, but I don't want to get overambitious ;-)

We might also take this opportunity to think about the following (both of
which have been discussed):

replacing dbf with sqlite as the default attribute management system
changing the raster file architecture to something more along the lines of
the current vector file architecture.
