[GRASSLIST:646] Shortest distance routing

[Alexander Pucher]

Hi, just a quick question,

can somebody point me to some information on how to work with network 
(esp. road network) analysis in GRASS. Let's consider I have a vector 
databases of a city's road network and want to find out the shortest 
distance between point A and B. 

All I can find by looking at the docs and searching through google are 
more or less surface runoff routing examples.

Thanks for any help.

Best regards,
alex.
