+Specifying Single Revisions
+
+ 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.
