Google Code: Force comment on commit

I just started using Google code hosting and am a beginner at working with Subversion. I was wondering if there is a way to enforce a rule that no co开发者_运维知识库mmits can be made without comments. I was researching into it, and I did find a way to do this on subversion - it involves creating a pre-commit hook. But I don't think I can do this in Google code (or am I wrong about this?)

Do you know how I can enforce this? Thanks!

I posted this to the Google Code issues list as a feature request and it was reviewed and accepted as an enhancement request. But on the mean while, they provided the suggestion of using the email on commit option. This way if someone committed without comments, you can can at least notice it right away and let them know.
