[GRASS-dev] r3.univar

[Paul Kelly]

I haven't looked at any of the code, but if as you say it is mostly 
identical to r.univar then perhaps it might be possible to compile 
r.univar and r3.univar from the same directory, as is done for r.mapcalc 
and r3.mapcalc? It would save cloning of code in the source distribution, 
make bugfixes easier - and an easy way for you to share that new function.
Just an idea,

Paul
