[Zope-CMF] CMFSetup: workflow scripts as external methods

[Jens Vagelpohl]

There's an outstanding issue in the collector about workflow scripts  
that are external methods. Currently, creating a snapshot of a site  
with external methods on the Scripts tab of a DCWorkflow will just  
blow up. The real question here is: Do we want to support that at  
all? Taking a quick look at the code two options come to mind:

- When extracting workflow script information, external methods are  
specifically ignored. The documentation is updated to reflect the  
fact that only DTMLMethods and Script (Python) (or items derived from  
them/behaving like them) are supported as far as import/export goes.

- External methods gain support by extending the saved information to  
collect module/function values for external methods instead of trying  
to read the body. This *will* make an import blow up if the  
filesystem code the external method relies on is not in the expected  
location.

I would favor the latter route, but would volunteer to implement  
either solution. What's the consensus? Or are there other alternatives?
