SVN Granural post commit mail hook

Is there ready solution for开发者_C百科 post commit hook for sending mails that supports finer granularity, e.g.

I have few groups of interests, developers only interested in changes in trunk, developers interested in changes only in some specific sub directories of the trunk.

By default post-commit hook support per repo mails.

We couldn't find an off-the-peg way to do it. We ended up modifying svnmailer such that for each affected directory it looks for a subversion property listing email addresses (and does this for every directory up to the repository root) and builds up a set of email addresses to use as recipients.

It works pretty well, and lets developers register themselves for notifications by setting the property.
