[Qgis-developer] GGL2 - QGIS integration

[G. Allegri]

What do you mean with "SEXTABTE/QGis" integration? Do you mean launching
GGL2 commands from inside SEXTANTE (directed to the hosted GGL2 engine), or
porting GGL2 to Python?
I see on your repo a basic Python implementation to call GGL2 through
Popen. Do you mean something like that?

Sorry for so many questions, I ask them just to understand, because you're
project is very interesting and I like to think about possible future
applications.
I like very much domain languages. On this topic I also follow JEQL, from
Martin Davis, and OrbisGIS [2] with its GDMS and GRAP tools.
