Manuel,
  Are you on the FPP committee?  I looked at the fedora packaging policy 
and it is rather similar except it has periods where we have 
underscores.  It would be nice if fedora could expand the policy to 
allow the underscore style as well.  Both approaches work just as well.  
And to me the underscore form is a lot more readable.
  Also, there isn't a lot of examples in the FPP regarding adding the 
vcs revision number into the release string.  I like the way we do it 
because it's lexically correct always.  Maybe this could be added to FPP?


Regards,
Gerry
