[GRASS5] r.profile

[Bob Covill]

Helena & Hamish,

I sent Peter a test version of r.profile this morning that allows 
coordinates to be piped in. Basically coordinates could be provided in 
three ways ...

coords from file
cat mycoordinates.txt | r.profile input=foo output=bat

select coords interactively
r.profile -i input=foo output=bat

coords on command line
r.profile input=foo output=bat profile=e,n,e,n,...

If you are interested I can make this available for testing.
