Pulling out directory

[Eric Siegerman]

You can get the directory's history into the new repo -- something along 
the lines of:
   1) use "hg convert" to split the directory out into its own little 
repo -- but put it, within that little repo, *not* at the root, but 
rather at the relative pathname you want it to end up in in the final repo
   2) use "hg pull --force" to get the little repo that you created at 
step #1 into the final repo
   3) at this point, the final repo has two completely unrelated DAGs in 
it; use "hg merge" to tie them together

You'll get a history something like this (left column is the stuff that 
was already in the new repo; right column is the directory you've just 
pulled in and merged):

o
|\
| \
|  \
|  o
|  |
|  o
|  |
|  o
|
o
|
o
|
o

What I don't know is how to coalesce the two histories back together as 
though they'd never been split up in the first place. You could get a 
crude approximation, though (with a fair bit of manual effort) using 
http://wiki.monotone.ca/ZipperMerge/ .
