  DESCRIPTION
  -----------
@@@ -177,11 -177,14 +177,19 @@@ behavior
  	current patch being applied will be printed. This option will cause
  	additional information to be reported.
  
 +--recount::
 +	Do not trust the line counts in the hunk headers, but infer them
 +	by inspecting the patch (e.g. after editing the patch without
 +	adjusting the hunk headers appropriately).
 +
+ --directory=<root>::
+ 	Prepend <root> to all filenames.  If a "-p" argument was passed, too,
+ 	it is applied before prepending the new root.
+ +
+ For example, a patch that talks about updating `a/git-gui.sh` to `b/git-gui.sh`
+ can be applied to the file in the working tree `modules/git-gui/git-gui.sh` by
+ running `git apply --directory=modules/git-gui`.
