[Zope-CMF] [dev] GenericSetup: more refactoring - a small proposal

[yuppie]

Hi!


The setup handlers for adapter based import / export are just 
boilerplate. I'd like to move the complete responsibility for setting up 
tools to importToolset / exportToolset.

toolset.xml already contains all the necessary information if we use the 
ID of the tool for computing the file names. catalog.xml would e.g. 
become portal_catalog.xml.

GenericSetup would need some BBB code to handle CMF 1.5 profiles. 
Old-style tool handlers can still have their own registry step.

This would make writing and maintaining tool handlers much simpler. On 
the other hand we loose some flexibility:

- import/export of selected tools from a bigger profile: don't think we 
really need that
- handling import dependencies: currently the 'workflow' step depends on 
the 'typeinfo' step. AFAICS we can easily get rid of that dependency.

Nevertheless I think the refactoring would be an improvement and if 
there are no objections I'll work on this change.


Cheers,
