I have a pre-commit hook that allows you to set a directory as "add-only". This was mainly for the tags directory. You can create a tag, but once created, it can't be modified.
This should fit well in your process. You can give it a try. I've just done a major rewrite that is more object oriented and allows you to use LDAP groups for file permissioning. However, this link is to the old tried and true version. <http://db.tt/H3o1i7S> You'll need Perl on your Subversion repository server to run this, but you shouldn't need any optional CPAN modules. -- David Weintraub qazw...@gmail.com
