[Grub-dev] How to create your own workunit?

[Bani]

I would like to try crawling some URLs specified by me, but I'm not
sure about how to create my own workunit. I've tried getting one from
http://dispatch.grub.org/do/workunit and editing all the sites, but in
the end I got a 401 Unauthorized. This doesn't seem right, so I'm not
sure about how I should generate my PUT line.
The workunit I tried to use is at http://www.ime.usp.br/~bani/tmp/workunit
