`hg heads [-r REV] [REV]...`

A '''head''' is a [[ChangeSet|changeset]] with no child changesets. The [[Tip|tip]] is the most recently changed head. Other heads are recent [[Pull|pulls]] into a [[Repository|repository]] that have not yet been [[Merge|merged]].

If you have just made a commit, that commit will be
the tip. Alternately, if you have just pulled from another
repository, the tip of that repository becomes the current tip.

Mercurial supports [[MultipleHeads|multiple heads]] concurrently within a single repository.
