[Zope] sha and newbie db question.

[Jens Vagelpohl]

please keep this on the list so everyone can see it...

you can pass context by making "self" the first argument in the method 
defined in the module you put in the Extensions folder. then use self like 
you use context. it will be passed in automatically when you call the 
external method.
