[GRASS5] Re: gis.m: Zoom and region overhaul, bindings

[Michael Barton]

Wow. This and the packaging sounds like a great improvement--turning my
amature attempt at interface building into something quite slick. You should
stick your name on the headers if you haven't yet done so. I'm looking
forward to trying it out. Can I just download all the gis.m directory or is
there stuff elsewhere?
