If you want to do an anonymous pull of something with monotone, a few steps are required:

• mtn --db=... db init
• mtn --db=... pull ... ...
• mtn --db=... co .. ..

I created a little script (apull.sh) that automates this:

• Creates the database in a temporary directory
• does an anonymous pull
• checks out the branch that you pulled
• moves the database from the temporary directory into the monotone metadata directory _MTN

You can download a version of it here.

You can also get it from the monotone server on mudshark.org on the org.mudshark.jack.proj.mtn-apull branch.
