I am currently updating the unofficial WebOb packages for Arch Linux.
Parts of the documentation won't build because they reference
UnicodeMultiDict or send_request, both of which have been removed.
There is an issue on GitHub at:
https://github.com/Pylons/webob/issues/53
I would attach a patch to the GitHub issue, but I don't know enough
about WebOb to remove the other references to UnicodeMultiDict in the
documentation.
