-Mercurial supports several ways to specify individual revisions.
-
-A plain integer is treated as a revision number. Negative integers are
-treated as sequential offsets from the tip, with -1 denoting the tip,
--2 denoting the revision prior to the tip, and so forth.
-
-A 40-digit hexadecimal string is treated as a unique revision
-identifier.
-
-A hexadecimal string less than 40 characters long is treated as a
-unique revision identifier and is referred to as a short-form
-identifier. A short-form identifier is only valid if it is the prefix
-of exactly one full-length identifier.
-
-Any other string is treated as a tag or branch name. A tag name is a
-symbolic name associated with a revision identifier. A branch name
-denotes the tipmost revision of that branch. Tag and branch names must
-not contain the ":" character.
-
-The reserved name "tip" is a special tag that always identifies the
-most recent revision.
-
-The reserved name "null" indicates the null revision. This is the
-revision of an empty repository, and the parent of revision 0.
-
-The reserved name "." indicates the working directory parent. If no
-working directory is checked out, it is equivalent to null. If an
-uncommitted merge is in progress, "." is the revision of the first
-parent.
