You'll get just what you ask for.
A little table to show it:
Code:
src-all = src
ports-all = ports
doc-all = doc
where in this table, the RHS == collection line in the supfile, LHS == directory to fetch from CVS (essentially) that relates to said collection. The other collections available generally follow the same concept, e.g. src-usrbin will nab sc/usr.bin; everything of interest can be found in /usr/share/examples/cvsup/
Thus, if I put this in a supfile:
Code:
*default prefix=/usr
src-all tag=RELENG_7
ports-all tag=.
doc-all tag=.
I would expect a call to csup/cvsup with it to result in /usr/{src,doc,ports} containing the comparable items from CVS. If not, I'd kick myself for not reading the manual more thoroughly ;-)
