[GRASS5] r.terraflow not found...

[Laura I. Toma]

It is easy to compile r.terraflow.  Go in the r.terraflow directory
<grass-src-dir>/src.contrib/DUKE/r.terraflow
and run bin/gmake5
This should compile two executables, r.terraflow and r.terraflow.short and
place them in
<grass-src-dir>/dist.<platform>/etc/bin/cmd/
To see them from grass5 you copy them to (or make symbolic links)
<grass-dir>/bin/grass5/

Let me know if you have troubles.
