Cool, I think this is getting more useful now. However, there is still a 
catch we have to answer/resolve.

The spec says Python 2.4 or later. While I understand that the LSB 
cannot force distributions to schlep Python 2.4 for all eternity and we 
don't want to add Python 2.4, then deprecate it right away only to add 
2.5 and repeat forever more, we need to somehow find a way to "freeze" 
the behavior via the spec.

Right now the links for the modules point to the 2.5 documentation when 
they probably should point to the 2.4 documentation. The way I interpret 
what we are trying to do is as follows:

Distributions may supply any version of Python (2.4 or later). 
Applications can depend on the 2.4 interfaces.

This means if in 2.6 one of the interfaces changes, app vendors still 
can get the 2.4 behavior. Otherwise we just broke the LSB deprecation 
policy (assuming 2.6 is available less than 6 years after 2.4 was 
released). Therefore the documented interface behavior should be the 2.4 
documentation and not the latest (currently 2.5) or we would change the 
spec via link every time a new version of python is released.

IMHO we should clearly document this intend and we should also alert 
users to the fact that the links point to what the LSB wants to include, 
i.e. documents describing the 2.4 behavior.

For cPickle for example that would be


instead of

 http://docs.python.org/lib/module-cPickle   (this is the 2.5 version 
and will be 2.6 in the future).

I know we do not want to duplicate the documentation but it might be 
worth it to just host the Python 2.4 docs as a copy on the LF site to 
assure that we don't end up with broken links if the Python folks decide 
to change their site or worse yet end up pointing to the wrong interface
