Does anyone have a nice awk for svn log output?

I want to search the commit messages for a string, it's easy to pipe svn log to a grep, but because the message and the rev are on separate lines, it's a little more complicated.

i.e.

svn log ./ | searchSvnMessages.awk artf29999

I was hoping that someone else had done the dirty work that I could piggyback on?

If you only need to search the first line of each log entry and you are using GNU grep, you can do svn log . | grep -B2 artf29999.

You can also use svn log ... --xml to get xml output, which might be easier to parse. Alternatively you can use various script bindings to get richer objects instead of parsing.
