== Revision ==

In Mercurial, the term '''revision''' can have two different meanings, depending on context.

Most often, "revision" refers to a distinct [[ChangeSet|changeset]] in a [[Repository|repository]], for example by specifying a repository-local [[RevisionNumber|revision number]] for the {{{--rev}}} option of the {{{hg update}}} or the {{{hg merge}}} command (conceptually referring to "a revision of the repository").

The term "revision" is also used as the short form for the longer term "file revision", which refers to a certain version of a file stored in the repository (conceptually referring to "a revision of a file").

This dual-use of the term "revision" naturally follows from the fact that Mercurial uses the same technical method for storing changeset information and for storing file versions in the repository, namely the [[Revlog|revlog]] format (see [[Design]]).
