#This digs through a pile of bugzilla's and populates the cwd with a big
#collection of bug-docs in per-filetype dirs with bug-ids as names with
#prefixes to indicate which bug-tracker, e.g.

#fdo-bugid-X.suffix
#rhbz-bugid-X.suffix
#moz-bugid-X.suffix
#
#where X is the n'th attachment of that type in the bug
