It does. Check out the fGIS manual page at
http://www.digitalgrove.net/Help/tools.htm#attributes
Just create yourself a dictionary of attribute values to apply to different
types of roads and other vector features (and by this I mean, grab a pen and
piece of paper and make up something consistent, or find a digitizing guide
from some agency that makes maps like the kind you want to make --- I tend
to use the US Forest Service's cartographic feature file digitizing guide
for vector layers I make in GRASS), use the attribute editor to assign them to
each vector feature, and when you write your shapefile those should go into a
dbf file.
