[darcs-users] Per-directory version control

If I recall, arch has some commands to handle this situation. Arch's solution
is for the exported directory to be its own arch project, which immediately
leads to solutions using darcs:
If you are using the 'push' model, then it seems like it would be very easy to
make a wrapper script that just pushed to both places:
$ cd /path/to/foo
$ darcs push /path/to/foo-project/foo
$ darcs push /path/to/bar-language/foo
where /path/to/*/foo is not added to either project
If you are using a 'pull' model:
$ cd /path/to/foo-project/foo
$ darcs pull /path/to/foo
$ cd /path/to/bar-language/foo
$ darcs pull /path/to/foo
I just checked and didn't see any --repdir option to 'darcs pull', but it would
reduce the second example to two commands.
The push model seems more easily scriptable, assuming all the repositories are
on different machines.
I'm certainly no expert in darcs, version control or patch theory (by the way,
David, thank you for publicly formalizing it; it was sorely needed... maybe it
existed somewhere in academia but your page was the first I'd seen of it), but I
didn't want this post to go unanswered (again?).
