[Zope] External Method importing modules

[Alan]

Dear Andreas and Jonathan, first a mistake: I want to access
'Extensions' folder as you mentioned Jonathan, not 'import'.

Andreas, I've done that, I can see several path there like
.../instance/Products/Sprout/src, .../lib/python/Zope2/Startup etc.,
but none for .../instance/Extensions.

I was hoping that I could get the path where 'Extensions' is because I
work with several zope installations in several platforms and I would
like to make my module independent of a variable inside its code that
should be manually adjusted for every situation.

And yes, I am aware about adding the path only once (that's why
there's a 'if') and then I avoid recursive insertions.

Cheers,
Alan
