If it is easy for you to execute commands, then something
like:

/bin/make -f /usr/ports/shells/bash2/Makefile -V PORTVERSION

might give you the result you want.  But I do not know if
that will work for all ports.

Well, one of my goals for this project is to make it easier
for others to write programs which do their own processing
of the ports-files.  I am a little worried about how long
it would take us (Darren and I) to figure out the right XML
format, and how to process it, but maybe we really need to
do that.

Would it be useful-enough if the pd-handling program
could spit out a true XML-formatted document, once we knew
what that was?  I realize this is rather lame, but it would
allow us to keep this key program pretty small and simple.

Well, at the moment I am *not* using XML...  :-)

Right now I'm just looking for feedback.  Thank you for
providing some more ideas for Darren and I to think about.
