Add check of herds in metadata.xml (Revision: 15471)
This is a multi-part message in MIME format.Hello!
Motivated by an earlier patch by idl0r I've been working on an
etree-based herd check for repoman. Right now it only checks for herds.
As this is my first non-trivial contribution to repoman, I felt like
asking for review before extending it further.
In case you would do only minor modifications you can apply right away
