Rearrange this a bit while I think about the whole problem of fetching

multiple targets when dealing with creating a set of distribution files
from scratch.  Another problem is *verifying* that a given file fetched
from its HOME_LOCATION is the one we wanted (what if the stupid ftp site
maintainer updated it in place?).  Rich Morin pointed this out and suggested
some solutions.  I need to think about it some more (suggestions?).

For now, we have a seperate `fetch' and `extract' target.
