You are right, there is one `-doc` too much.  Hmmm, in my concept it 
would be better to drop `python-qutip-doc` as the last step of migration 
(see below) and instead mark

  * python-qutip-core-doc
    Replaces: python-qutip-doc (<< 5.1.1-20)
    Conflicts: python-qutip-doc (<< 5.1.1-20)

To migrate without having version issues, the idea is to implement the 
packages step by step.  I will mark in `python3-qutip-core` like

  * python3-qutip-core
    Replaces: python3-qutip (<< 5.1.1-20)
    Conflicts: python3-qutip (<< 5.1.1-20)

So it should just possible to install one of them during migration.

If I have finished the packaging in the last step we can make 
`python3-qutip` to a pure metapackage which

  * python3-qutip
    Depends: python3-qutip-core
    Recommends: python3-qutip-{qip,qtrl,qoc},
    Suggests: python-qutip-{qip,qtrl,qoc}-doc

This should hopefully trigger `apt` to upgrade to the new packaging 
structure.  We should do this if the Trixie freeze is over.

As last step it should be possible to drop `python3-qutip-doc` from the 
Debian archives.

**********************************************************************
* For Trixie

I think the best solution for Trixie is to rollback to 4.7.5-2 with a 
version scheme like

  * python3-qutip     5.1.1-2+really4.7.5-2

I start the migration with version

  * python3-qutip-*   5.1.1-20

This should not prevent the migration in unstable as I do not touch 
python3-qutip.  During Trixie freeze I report a serious bug to every new 
package, so that these do not going into Debian Testing for Trixie.

That's the plan,
Dirk =)
