Ummm, I'm not sure I understand your question about alts and QA.

Alts in scmproj is equivalent of branch for meta (mega?) project.
Alts described several set of component branches. Initially they are introduced to support
(emulate?) something like colocated branches.

Currently we're using alts to differentiate between main (trunk) branches of project,
and developers (features) branches of the same project.

Thanks for moral support.
