The intelligence is in the people who put the packages together, and
try to predict the problems that users have.  The packaging of that
intelligence is secondary.  Plus, there's a lot of registry stuff,
desktop setup, and mount table stuff to deal with.

It does.  The problem was that there was already a set of tar/gzip
sources in cygwin, and they were *not* the right sources for the
versions in setup, so you end up with *two* sets of tar/gzip sources.

Setup currently does not include tar or gzip sources.  I used zlib and
wrote my own tar extractor.  Tar's a pretty trivial format.

So, instead of one setup program, the user would run two?
