sites to dig_cat and dig_att

I seem to recall that someone was asking about how to use
data of the form:

     23|23423|#1 label
     23|23423|#1 label
     23|23423|#1 label

(a site file) to label a vector map. (If it wasn't on this
list, then consider this just FYI). I've hacked up a shell
script (with man page) to do this. If this would be useful
for anyone, perhaps I could put it in the incoming directory
on moon.
