+From 18f71a50a9000e7558ae48a971fa301d76220ff0 Mon Sep 17 00:00:00 2001
+From: Prathmesh Prabhu <pprabhu@chromium.org>
+Date: Tue, 10 Mar 2015 17:04:40 -0400
+Subject: [PATCH] protoc: Add options to redirect input/output to files.
+
+When using protoc to encode/decode protobufs, the input/output was from
+stdin/stdout only. This patch adds command line flags to specify files to read
+the protobuf from and and write the encoded/decoded protobuf to.
