robots.txt with hg serve?

[Tim Post]

Does anyone know if there's a way to allow a hit on robots.txt if the
repo is being served by hg serve -p -d ?

I want to run some repos on different ports that exist for very
different reasons. Some of them versioning /etc updated via a inotify
daemon, some of them hosting repos, some just hgweb.

I don't care if the public finds the ones accessible to the world, but
I'd like to keep Google and Yahoo out of my code :) Is there a way to
use robots.txt with the hg serve option?

Thanks in advance, I didn't see this asked or answered anywhere.
