Just ignore my comments on the file store.  I missed the FileManager and
FileManagerImpl classes ;-)

Is it pluggable at least, or would I need to do some work on this as
well?  I'll need to make things work with Endeca search anyway, so I
might need to make the implementation a bit more general.

Is there some way around this?  I'm thinking of perhaps storing the
uploads in a database table.  Is this something that other people would
also be interested in?  Perhaps I can do some work to make the
implementation pluggable and contribute the source.

If you give me access to the roller wiki I'll rustle up a page or two
for this.  At some stage I filled out and signed all the legal stuff and
mailed it to Apache.  Don't know if it ever made it there.

I'll do some digging in the mailing archives.  I can do wiki pages that
summarizes Allen's post as well as things that I stumble across.
