'''track a line of development with movable markers
Bookmarks are local movable markers to changesets. Every bookmark
points to a changeset identified by its hash. If you commit a
changeset that is based on a changeset that has a bookmark on it, the
bookmark shifts to the new changeset.
It is possible to use bookmark names in every revision lookup (e.g.
:hg:`merge`, :hg:`update`).
By default, when several bookmarks point to the same changeset, they
will all move forward together. It is possible to obtain a more
git-like experience by adding the following configuration option to
your configuration file::
[bookmarks]
track.current = True
This will cause Mercurial to track the bookmark that you are currently
using, and only update it. This is similar to git's approach to
branching.

'''track a line of development with movable markers
Bookmarks are pointers to certain commits that move when
committing. Bookmarks are local. They can be renamed, copied and
deleted. It is possible to use bookmark names in :hg:`merge` and
:hg:`update` to merge and update respectively to a given bookmark.
You can use :hg:`bookmark NAME` to set a bookmark on the working
directory's parent revision with the given name. If you specify
a revision using -r REV (where REV may be an existing bookmark),
the bookmark is assigned to that revision.
Bookmarks can be pushed and pulled between repositories (see :hg:`help
push` and :hg:`help pull`). This requires the bookmark extension to be
enabled for both the local and remote repositories.
