Since the binaries will differ for different releases, and we have a
/pool structure with shared debs for all releases, this doesn't work.
You need to use different release numbers for different uploads.

A common scheme is:

  0.8.0  for the development release (jaunty)
  0.8.0~intrepid1 for a backport/build in intrepid
  0.8.0~hardy1 for a backport/build in hardy

"~" is a special operator which means "smaller than the version before
it", i. e. it is predestined for backports. Version numbers in earlier
releases must always be lower or equal than the ones in later releases.
