  ok, that's useful information that doesn't seem to be documented
anywhere (or is it?).

  however, if a regular recipe can be used as the basis for a package
group, would it not still have to contain "inherit packagegroup" to be
defined as a package group?  or can any regular recipe act as its own
package group?  i examined the "psplash" recipe and i saw nothing that
suggested it was available as a package group.

  i realize these are nitpicky questions but it's the sort of thing
someone's guaranteed to ask me at some point, so i want to nail it
down.
