 DESCRIPTION
@@ -63,6 +63,29 @@ OPTIONS
 * when both sides adds a path identically.  The resolution
   is to add that path.
 
+--prefix=<prefix>/::
+	Keep the current index contents, and read the contents
+	of named tree-ish under directory at `<prefix>`.  The
+	original index file cannot have anything at the path
+	`<prefix>` itself, and have nothing in `<prefix>/`
+	directory.  Note that the `<prefix>/` value must end
+	with a slash.
+
+--exclude-per-directory=<gitignore>::
+	When running the command with `-u` and `-m` options, the
+	merge result may need to overwrite paths that are not
+	tracked in the current branch.  The command usually
+	refuses to proceed with the merge to avoid losing such a
+	path.  However this safety valve sometimes gets in the
+	way.  For example, it often happens that the other
+	branch added a file that used to be a generated file in
+	your branch, and the safety valve triggers when you try
+	to switch to that branch after you ran `make` but before
+	running `make clean` to remove the generated file.  This
+	option tells the command to read per-directory exclude
+	file (usually '.gitignore') and allows such an untracked
+	but explicitly ignored file to be overwritten.
+
 <tree-ish#>::
 	The id of the tree object(s) to be read/merged.
