DESCRIPTION
-----------
OPTIONS
-------
+include::diff-options.txt[]
+
<tree-ish>::
The id of a tree object to diff against.
--p::
- Generate patch (see section on generating patches)
-
--r::
- This flag does not mean anything. It is there only to match
- "git-diff-tree". Unlike "git-diff-tree", "git-diff-cache"
- always looks at all the subdirectories.
-
--z::
- \0 line termination on output
-
--B::
- Break complete rewrite changes into pairs of delete and create.
-
--M::
- Detect renames.
-
--C::
- Detect copies as well as renames.
-
---find-copies-harder::
- By default, -C option finds copies only if the original
- file of the copy was modified in the same changeset for
- performance reasons. This flag makes the command
- inspect unmodified files as candidates for the source of
- copy. This is a very expensive operation for large
- projects, so use it with caution.
-
--S<string>::
- Look for differences that contains the change in <string>.
-
---pickaxe-all::
- When -S finds a change, show all the changes in that
- changeset, not just the files that contains the change
- in <string>.
-
--O<orderfile>::
- Output the patch in the order specified in the
- <orderfile>, which has one shell glob pattern per line.
-
--R::
- Swap two inputs; that is, show differences from cache or
- on-disk file to tree contents.
-
--cached::
do not consider the on-disk file at all

If '--cached' is specified, it allows you to ask:
- show me the differences between HEAD and the current index
+ show me the differences between HEAD and the current cache
contents (the ones I'd write with a "git-write-tree")
-For example, let's say that you have worked on your index file, and are
-ready to commit. You want to see eactly *what* you are going to commit is
-without having to write a new tree object and compare it that way, and to
-do that, you just do
