1) Make a new .xml file

Run 'make comps-f19.xml' in a git checkout.

2) Create a new repository using that comps file

createrepo -g your-new-comps-f19.xml /some/path (it doesn't need to have
packages in it)

3) Create an /etc/yum.repos.d repository file that points to that path

4) Enable that repo

5) Test your group with 'yum grouplist', 'yum groupinfo', etc.
