[plt-scheme] setup-plt documentation

Is this the only documentation on the web for .plt files and setup-plt?

http://download.plt-scheme.org/scheme/plt/collects/setup/doc.txt

Also, setup-plt could probably use a man page (in plt/man/man1), like
the other plt executables.

Considering this is intended to be the primary means for distributing
collections, setup-plt seems to be very under-documented (and
unpublicized).  At the very least, the add-ons page
http://www.cs.utah.edu/plt/develop/ should probably explain what to do
with the .plt files that it offers for download.  Even something like
"use `File->Install .plt File...' in DrScheme" would help.
