[GRASS-dev] Re: g.rename consolidation

[Michael Barton]

TclTk has a nice progress bar capabilities. But it needs consistent
information to read. There is a progress bar built into the map display that
tracks display progress. For modules that output consistent progress
information, there is the green progress bar in the autogenerated dialog.
The holes are for modules that don't output progress information in a
consistent format and for scripts that tend not to output it at all.
