[Rpm-metadata] createrepo 0.4.3

[seth vidal]

hi folks,
 I just released createrepo 0.4.3 - it includes the cachedir option and
I mostly included it for work regarding the fedora extras buildsys.
However, it should help a lot of people speed up their metadata
generation. The next big change will be 0.5.0 which should include an
array of new items.

Some ideas:
 - querying and xmlrpc server for non-changelog update information
(errata notes)
 - possible: specifying the file globs used for determining what files
get added to primary.xml or not
 - possible: multiple runs over the metadata to help fill out the
metadata
 - removable media ideas and handling
 - other ideas?
