[Zope] open again

[Abraham Arellano Tavara]

thanks i'll try to make this real, but i'm new in this i for the things that 
i read i thought that i can use the command "open" easily, but i see that is 
not possible..
I have another question, which is the BASEPATH, the path to the pakage 
YourProject??
&& where goes the last part of code that you show to me?? in the init.py or 
in a external method in the directory Extensions??
sorry for these questions... first time in zope..
