Create, remove or modify a tag naming a revision.
bzr tag [TAG_NAME]
Tags give human-meaningful names to revisions. Commands that take a -r (–revision) option can be given -rtag:X, where X is any previously created tag.
Tags are stored in the branch. Tags are copied from one branch to another along when you branch, push, pull or merge.
It is an error to give a tag name that already exists unless you pass –force, in which case the tag is moved to point to the new revision.
To rename a tag (change the name but keep it on the same revsion), run bzr tag new-name -r tag:old-name and then bzr tag --delete oldname.
If no tag name is specified it will be determined through the ‘automatic_tag_name’ hook. This can e.g. be used to automatically tag upstream releases by reading configure.ac. See bzr help hooks for details.
