Here is a patch to mkbranch that would be the first step to getting branch seeds:

}}}

Once we get this in after the release and create symlinks for all existing packages/branches, it'll be a simple edit to get-webfiles.sh to create these seeds.

Patch committed to mkbranch on cvs1.

Kevin just did a test with a new package, and it seemed to work OK. get-webfiles.sh has also been modified to create seeds from these branch directories now - I'm doing a manual run now which will take a while, but the new seeds should show up at http://cvs.fedoraproject.org/webfiles/ soon.
