+SPECIFYING REVISIONS
+--------------------
+
+A revision parameter typically, but not necessarily, names a
+commit object. They use what is called an 'extended SHA1'
+syntax.
+
+* The full SHA1 object name (40-byte hexadecimal string), or
+ a substring of such that is unique within the repository.
+ E.g. dae86e1950b1277e545cee180551750029cfe735 and dae86e both
+ name the same commit object if there are no other object in
+ your repository whose object name starts with dae86e.
+
+* A symbolic ref name. E.g. 'master' typically means the commit
+ object referenced by $GIT_DIR/refs/heads/master. If you
+ happen to have both heads/master and tags/master, you can
+ explicitly say 'heads/master' to tell git which one you mean.
+
+* A suffix '{caret}' to a revision parameter means the first parent of
+ that commit object. '{caret}<n>' means the <n>th parent (i.e.
+ 'rev{caret}'
+ is equivalent to 'rev{caret}1'). As a special rule,
+ 'rev{caret}0' means the commit itself and is used when 'rev' is the
+ object name of a tag object that refers to a commit object.
+
+* A suffix '~<n>' to a revision parameter means the commit
+ object that is the <n>th generation grand-parent of the named
+ commit object, following only the first parent. I.e. rev~3 is
+ equivalent to rev{caret}{caret}{caret} which is equivalent to\
+ rev{caret}1{caret}1{caret}1.
+
+* A suffix '{caret}' followed by an object type name enclosed in
+ brace pair (e.g. `v0.99.8{caret}\{commit\}`) means the object
+ could be a tag, and dereference the tag recursively until an
+ object of that type is found or the object cannot be
+ dereferenced anymore (in which case, barf). `rev{caret}0`
+ introduced earlier is a short-hand for `rev{caret}\{commit\}`.
+
+* A suffix '{caret}' followed by an empty brace pair
+ (e.g. `v0.99.8{caret}\{\}`) means the object could be a tag,
+ and dereference the tag recursively until a non-tag object is
+ found.
+
+'git-rev-parse' also accepts a prefix '{caret}' to revision parameter,
+which is passed to 'git-rev-list'. Two revision parameters
+concatenated with '..' is a short-hand for writing a range
+between them. I.e. 'r1..r2' is equivalent to saying '{caret}r1 r2'
+
+Here is an illustration, by Jon Loeliger. Both node B and C are
+a commit parents of commit node A. Parent commits are ordered
+left-to-right.

+ A = = A^0
+ B = A^ = A^1 = A~1
+ C = A^2 = A^2
+ D = A^^ = A^1^1 = A~2
+ E = B^2 = A^^2
+ F = B^3 = A^^3
+ G = A^^^ = A^1^1^1 = A~3
+ H = D^2 = B^^2 = A^^^2 = A~2^2
+ I = F^ = B^3^ = A^^3^
+ J = F^2 = B^3^2 = A^^3^2
