user specified categories, in a vector map.

Apparently-To: grassu-list@zorro.cecer.army.milDoes any one know of a way to calculate the total length of all lines within

Was this ever addressed? I have a program half-written which will
give the perimeter of all areas with a specified category.
v.catcount vect=vector_map c=1
Would this help (if your problem is not already solved)?
