+NAME
+----
+git-apply - Apply patch on a GIT index file and a work tree
+
+
+SYNOPSIS
+--------
+'git-apply' [--no-merge] [--stat] [--summary] [--check]
+[--index] [--show-files] [-] [<file>...]
+
+DESCRIPTION
+-----------
+Reads supplied diff output and applies it on a GIT index file
+and a work tree.
+
+OPTIONS
+-------
+<file>...::
+	The files to read patch from.
+
+-::
+	Instead of reading from a file, read from standard input.
+
+--no-merge::
+	The default mode of operation is the merge behaviour
+	which is not quite implemented yet.  This flag
+	explicitly tells the program not to use the merge
+	behaviour.
+
+--stat::
+	Instead of applying the patch, output diffstat for the
+	input.
+
+--summary::
+	Instead of applying the patch, output a condensed
+	summary of information obtained from git diff extended
+	headers, such as creations, renames and mode changes.
+
+--check::
+	Instead of applying the patch, see if the patch is
+	applicable to the current work tree and/or the index
+	file and detects errors.
+
+--index::
+	When --check is in effect, or when applying the patch
+	(which is the default when none of the options that
+	disables it is in effect), make sure the patch is
+	applicable to what the current index file records.  If
+	the file to be patched in the work tree is not
+	up-to-date, it is flagged as an error.  This flag also
+	causes the index file to be updated.
+
+--show-files::
+	Show summary of files that are affected by the patch.
