'''mercurial bookmarks Mercurial bookmarks are local moveable pointers 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 is forwarded to the new changeset. It is possible to use bookmark names in every revision lookup (e.g. hg merge, hg update).
