[GRASS5] Fwd: Indic support in GRASS GIS with Indix2

Sun Jan 15 16:12:03 EST 2006

Hi Swapnil Hajare,

can you send the necessary changes as CVS diffs? It is explained
in the GRASS 6.1-CVS SUBMITTING file in the main source directory
how to generate it properly.

Then we can better see what needs to be changed.

thanks

 Markus
