[GRASS-user] Handling exceptions with Python

I am fairly new to both Python and Grass...

I am trying to catch exceptions thrown up by GRASS using try/except but
can't seem to get it working!

For example

grass.run_command('v.in.ogr', dsn=sLayer, output=sLayerName, quiet=True)

With the above I am trying to load a vector layer with the wrong projection,
the error prints to screen and then continues with the rest of the script
when I want to catch the error, log it and then exit.  I have looked at the
error def here http://grass.osgeo.org/programming7/core_8py_source.html but
can't make sense of it!

Any help greatly appreciated.

Regards, Phil
