[GRASS-dev] Re: g.rename consolidation

[Martin Landa]

Hi,

just to summarize, I suggest to reduce verbosity levels to three levels:

--q 0 MIN_LEVEL (only warnings + fatal_errors)
     1 STD_LEVEL (progress information)
--v  2 MAX_LEVEL (any "useful" information, another points is what is "useful")

E.g. Vect_build () output:

0 ... nothing printed
1 ... Registering lines: ... , etc.
2 ... all current info

Three level are enough I think, then we should move selected messages
to G_debug (1, ).

Any objections (in case I missed something)?

Martin
