[PATCH 00 of 12] RFC: Overlay repositories

[Brendan Cully]

Hi,

Here's an RFC implementation of overlay repositories. These are
repositories that refer to a parent repository for revisions that
aren't available locally. There's a page on the idea at

http://www.selenic.com/mercurial/wiki/index.cgi/OverlayRepository

At the moment the overlay repository instantiates the parent when it
is instantiated. I'd like to defer this until the time that older
revisions are actually used, but I haven't gotten to that yet.

There's also no attempt here to handle missing revisions. That'd be
nice at some point.

The patch queue is at http://hg.kublai.com/mercurial/patches/overlay,
