more code and an idea

Hi all,
 So I wrote the repomd generating code - and incorporated it all in one
command for the genpkgmetadata script.

the repomd.xml file is _just_ describing the timestamps and md5sums and
locations of the other metadata files. no other information about the
repo is being housed there in this take on things. Please tell me what
you think about this for the format.

Also,  I was talking to someone from ximian in irc the other day and
they mentioned a need for versions in the groups/comps file.

ie:
 <group>
   ...
   <packagereq name='foo'>
     <version epoch="1" ver="1.1.19" rel="12"/>
   </packagereq>
 </group>

Is that something other people would be interested in? would this work
out overall?
