Plone 4 Users Manual Licence

Hello.

I'm translating the Plone 4 User's Manual

  http://plone.org/documentation/manual/plone-4-user-manual

to Spanish. I would like to share the results, but I can't find the
licence of the manual.

If there is no licence explicitly attached to it, that means a standard
copyright (resctrictive) licence, so I would not be allowed to publish
anything.

I would like to know the licence, and I would ask you to specify it with
the manual, if possible.

Also, it would be good if the licence was as free as possible, so that
every effort, be it commercial or not, reverts to the community.

BTW, having the sources for the drawings in the manual would be very helpful.

Thank you.

Pablo.
