forcing log entry during commit

I would like to force users to write a log entry about the nature of the commit and have seen a hook script called enforcer that may help me do this.

Would some one mind getting me started on how to do this?

I imagine referancing some SVN variable to check if its not blank.

Perhaps the some thing that checks for a new line would do?
