Well, I just noticed that my message was maybe too cryptic for the
majority of the list :)

The explanation algorithm is used when the resolver cannot find a plan
to explain why the installation cannot proceed.

I decided to write a new algorithm after noticing last week that the
explanation of a failure to upgrade from a 3.6M5 with JEE packages to
3.6M6 could take more than one minute.

With the updated algorithm, it should take only a few seconds.

If you meet such kind of slow explanations, I would like to have your
feedback with the new algorithm.
