When I'm documenting PLaneT packages, I find I need to use
defmodule/this-package to make things work out right.  See:

    http://planet.racket-lang.org/package-source/dyoo/while-loop.plt/1/1/manual.scrbl

as a small example.



There's also a note in:

    http://docs.racket-lang.org/planet/Developing_Packages_for_PLaneT.html#(part._.Create_.Documentation__.Optional_)


that says that we should be using this-package-in, though I have to
admit that I've neglected to do this!
