[Exist-open] Create a zip that includes relative path only

[Thomas W. <tho...@gm...>]

Zip function has an option to include the full path of the archived 
collections and the resources.

I am working on a code where I need to produce zip file where a collection 
is zipped with the path of all subcollections and resources.
This zip file will be unzipped in a specific place in the file system by a 
standard archiving program to create a copy of the collection. That will be 
possible only if the zip contains not the full path to the collection 
/db/aa/bb/cc/COLLECTION/{content}. but only the relative path to the 
collection COLLECTION/{content}....

Can we add an option to the zip module 'relative-path' that will indicate to 
store the relative path only from the collection bellow.

Thomas
