Peter Chubb - 2009-09-04 03:31:40
There are occasions when developing when I want a package always to
grab the latest copy of a package.  Witht eh CVS fetcher you can do
this by setting the `date' tag to `now'.  This patch adds similar
functionality to the mercurial fetcher: if the revision to fetch is
`tip' then always grab from the server, and don't use the cached
tarball.

Oh, and I fixed a typo in the Class comment.
