[GRASS-dev] vector network questions

[Michael Barton]

Markus,

Thanks. It is good that you did this. When teaching it, however, is when I can really find out what is more and less understandable. I'm trying to make some additional suggested enhancements to the documentation to make this complex but useful set of modules more accessible. I'll copy you along with Moritz and Markus.

Michael
