[GRASS-dev] [bug #4493] (grass) gis.m fails to start GUI

[Cedric Shock]

Michael, et. al.,

We don't have an "official" tcl/tk compatibility requirement. However I put in 
SUBMITTING_TCLTK that programs should work with both 8.3 and 8.4, which I 
believe are both an absolute must. Due to the core nature of gui.tcl, I've 
been testing my changes to gui.tcl against 8.0, 8.3, and 8.4, even though 8.0 
compatibility results in slightly less readable code (no end- index 
notation).

I believe the tk options database was added in version 4. Poking around online 
I found a tcl7.0/tk4.0 manual that mentions the options database almost 
identically to the 8.4 manual (the interface is identical, the documentation 
has barely changed).

offrelief sounds like something that should be moved to options.tcl, where it 
can be specified and the tk version tested for once. We could also make a 
class of a toolbar select button to keep the options thin. This is probably 
the best idea. I'll whip one up some time soon as an example.
