Here, you are creating a branch. With darcs, this probably means
creating a second repository. Most likely, you would use "get" to pull
based on a tag in the original repo.
Contrast that with CVS, where you would be adding a new branch to the
single, centralized repo.

With darcs, the A code was never in the B repo, and vice versa. So the B
repo becomes the official repo, the entire A repo is deleted, and it is
as if A never happened.
If you want to bring some or all of A into B, you can, using "pull". In
fact, if other development is continuing that is common to both A and B,
you'll be pushing or pulling those changes between A and B on a regular
Note also that the B repo might be a copy on your local hard drive. Even
if A is public, B does not have to be. This represents the power of a
distributed RCS, where you can create a private fork without needing

I used ftp to mirror my local repo up to a web host for a while. It's
not ideal, but if your repo is small it's workable.
