best way to copy iPhoto library to another user?

[edgarbc1]

iPhoto 6.0.2

what is the best way to copy an iPhoto library to another user?
straight copy of entire Pictures/iPhoto Library folder?
(making sure to change read write permissions)
is there a batch changer of permissions?

is there a better way?
because there are at least 3 folders of photos... Data, Modified, and Originals
plus the index files which likely need to get changed too..

id rather not just share the photo library, i want a direct copy for the other user
to tweak as desired.
