[Zope-CMF] [dev] CMFSetup tool: small proposal

[yuppie]

Hi!


I'd like to fix http://collector.zope.org/CMF/264 and implement the 
"Allow import from snapshots." feature mentioned in the TODO list.

The compare feature already has some code to work with profiles *and* 
snapshots. I propose to reuse _getImportContext and the context ids 
starting with 'profile-' or 'snapshot-'.


That would mean:

- removing getProfileProduct, getProfileDirectory and 
setProfileDirectory from the ISetupTool interface

- removing the class attributes _product_name, _profile_directory and 
_root_directory from SetupTool

- adding a new _import_context_id attribute, getImportContextId and 
setImportContext methods


I don't plan to write any migration or backwards compatibility code. I 
hope nobody uses the current API outside of CMFSetup and reselecting a 
profile should not be to hard.

If there are no objections or better ideas, I'll make the proposed 
changes in CMF-1_5-branch and HEAD.


Cheers,
