WTF? (a/k/a Wow, am I ever slow on the uptake)

[George Mitchell]

I just now noticed (finally?) that my local ports repo is gradually
filling up with "*.pkg" files, and the "*.txz" files are turning into
symbolic links.  Everything is still working just fine, but I am
feeling rather embarrassed that it took me so long (since before
July 22, evidently) to catch on.  What happened, and where was it
documented?  I still don't see anything in /usr/ports/UPDATING.
