(I wasn't sure if this should go to netbsd-help, or tech-pkg; I opted for
the former...also, since I read these lists via the web-page, please
CC: replies to me.)

Is there something that I'm missing about maintaining distfiles?  In
particular, I want to remove distfiles that are no longer referenced.  
(Most commonly, this happens when pkgsrc is updated and a new version of
the distfile is called for, of course.)

I can think of a few somewhat-clunky ways.  Is there a clean way that I've
missed?  The clunky ways are:

 * Delete all distfiles periodically.  This might be acceptable if I had
   a faster Internet connection.

 * Just let them accumulate.

 * Do a ``touch time-stamp'', then ``make checksum'' on all packages and
   remove the unreferenced.  The problem here is that it brings _all_
   pkgsrc distfiles onto my computer.  In the past, this hasn't been too
   bad, since I already installed most of the big ones that I was aware
   of (EMACS, XEmacs, GNOME, KDE, the GIMP, ...).  However, it looks like
   (in addition to many smaller packages, as pkgsrc has grown) we now have
   a new champion for space-hogging: Crafty.  I don't intend on installing
   Crafty, and from the sound of it, at least one of its compressed data
   files is going to top 6GB.  That's a lot of data to download and keep
   around just for the privilege of deleting old distfiles.

 * Throw hardware at the problem (get a faster link) and go back to
   the first solution.  (^&


Is there a better way to do this?  I've never snaked through the pkgsrc
Makefiles, since they didn't look too inviting; what kind of trouble would
I be letting myself in for if I tried to add some kind of ``make
prunedistfiles'', or some such?


Thanks in advance for any suggestions/help.
