[GRASS5] collecting into a vector polygons statistics of raster pixels

[Yann Chemin]

Hello list,

How to collect raster pixels statistics (mean, min, max, stdev,
etc...) into polygons of a vector? I have been asked if this is
possible within GRASS GIS, but was unable to find a tool for that. In
Erdas, it is called "Zonal Attributes".
Anybody could please suggest a way, or point to the right direction
for making it?

thank you,
Yann
