svn copy vs svn add in pre-commit

Hi,

is there any way to determine if a commit to a repository is an svn copy or a shell level copy plus an svn add? I'm trying to limit people tagging to doing an svn copy, but I can't figure out how to determine if the current transaction (running in the pre-commit hook) is a copy or an add...

Any hints?

Cheers,

Ulli
