[GRASS5] New GRASS Quality Control System online

[Antoniol]

Dear Soren,

    at the moment the system subscription is still managed by hand. I
will immediately insert you
as one of the  GRASS  developers that will receive  the automatic
feedback upon
modification and cvs commit of C files.

I would also  uderline that we do very welcome any suggestion you think
will
improve the approach and make it more usefull to GRASS  developers.

All the very best

Giulio
