Collective.archive An addon to upload and download Archives from Plone

Source: https://bitbucket.org/mieszkowski/collective.archive/src/master/

This code only half works; upload content type "Archive" is functional. It unzips a tarfile's contents to a single directory preserving the paths. Could be useful..

The broken part; It should allow you to create a tar file or a pdf from a Collection.
actions.xml
url_expr is broken ... I can't figure out how to call custom adapter code from there...
The Zope Page Templates reference says you can add more Python Modules but doesn't say how.
"Unauthorized: import of 'collective.archive' is unauthorized"
Seems to be a permissions issue...
