Hi Andreas, hi all,

below patches are uploaded to CVS now. Your improvements are 
working fine!

Discussion is ongoing... :-)

As far as I know the "superview" was working once. Jacques Bouchard
already spent time on it, but it was not working (yet).
I guess it is a sort of workbench or a GUI similar to
ARCView. (activate maps on left border etc.)

> What is up with this r_mapcalc.tcl module?
I have written it once with vtcl. Due to my limited tcl knowledge
it is waiting for further integration into tcltkgrass.

You can run it stand-alone to see what it is doing: It is
a graphical calculator for r.mapcalc. I thought it would be
nice to have it in tcltkgrass once.

You are invited to integrate it (I don't know how). What's
missing: I would like to have the raster maps in a clickable window
(like already existing in tcltkgrass). A raw window is already there.
So the tool needs to be married with tcltkgrass.

> Do you think that a Tcl/Tk-log-in facility for GRASS would be nice?
It would be shurely a more friendly welcome to GRASS (perhaps
including the logo?). Nowadays it is difficult to teach students
to enter "list" to get a list of existing locations etc. A
graphical entry is more usual. If keeping the standard entry,
everybody will be happy.

Best wishes
