raster to vector

[Patricia Woodman]

Can anybody tell me if it is possible to create a vector file from a 
raster file, in GRASS 4.0

I need to create a contour map from a raster file showing elevation.

I cannot immediately see any straight forward way of doing this. Am I 
missing something obvious ?

Thanks for any hints

Paddy
