[GRASS5] user interface standardization

[Andreas Lange]

Hi Markus,

i would propose not to change any module that was introduced before
GRASS5.0, because older scripts might no longer run in that case. We
could discuss those changes for 5.1 again.

All new modules should use a standardized scheme. 
e. g. Import/Export: input=name output=name for all raster, sites and
vector modules.
e. g. display modules: map= for all raster and vector modules, file=name
for modules that can read from stdin in the "easting northing label"
format. 

For the shape/arc converters i personally think that it would be better
to explicitly give a name for the resulting vector file and to default
to the shapefile name if it is not used.  

I'll prepare a summary/proposal and check this in under the documents
section in CVS.

cu,

Andreas
