Distance analysis

[Bill Jackson]

Hello,

I've been searching the grass users archives for scripts that have to do with
distance analysis. So far I have not found any.

I want to write a script that would return the shortest distance from a specificparcel of land to a specific landuse class e.g. urban land.
 
r.cost seemed like a good place but if someone out there has some experience 
wih this I would like to hear from you.

Thanks in advance.
