-# http://code.google.com/p/gyp/wiki/InputFormatReference#Including_Other_Files

-# * Removed include of '../chrome/version.gypi'.
-# * Removed passing of version_full variable created in version.gypi:
-#   '--extra-variable', 'version_full=<(version_full)',
-
-# This file is meant to be included into a target to provide a rule

-# Copied from Chromium's src/build/protoc.gypi
-#
-# It was necessary to copy this file to WebRTC, because the path to
-# build/common.gypi is different for the standalone and Chromium builds. Gyp
-# doesn't permit conditional inclusion or variable expansion in include paths.
-# http://code.google.com/p/gyp/wiki/InputFormatReference#Including_Other_Files
-#
-# Local changes:
-# * Removed <(DEPTH) from include_dir due to difficulties with generated
-#   downstream code.
-
-
-# This file is meant to be included into a target to provide a rule
-# to invoke protoc in a consistent manner. For Java-targets, see
-# protoc_java.gypi.
-#
-# To use this, create a gyp target with the following form:
-# {
-#   'target_name': 'my_proto_lib',
-#   'type': 'static_library',
-#   'sources': [
-#     'foo.proto',
-#     'bar.proto',
-#   ],
-#   'variables': {
-#     # Optional, see below: 'proto_in_dir': '.'
-#     'proto_out_dir': 'dir/for/my_proto_lib'
-#   },
-#   'includes': ['path/to/this/gypi/file'],
-# }
-# If necessary, you may add normal .cc files to the sources list or other gyp
-# dependencies.  The proto headers are guaranteed to be generated before any
-# source files, even within this target, are compiled.
-#
-# The 'proto_in_dir' variable must be the relative path to the
-# directory containing the .proto files.  If left out, it defaults to '.'.
-#
-# The 'proto_out_dir' variable specifies the path suffix that output
-# files are generated under.  Targets that gyp-depend on my_proto_lib
-# will be able to include the resulting proto headers with an include
-# like:
-#   #include "dir/for/my_proto_lib/foo.pb.h"
-#
-# If you need to add an EXPORT macro to a protobuf's c++ header, set the
-# 'cc_generator_options' variable with the value: 'dllexport_decl=FOO_EXPORT:'
-# e.g. 'dllexport_decl=BASE_EXPORT:'
-#
-# It is likely you also need to #include a file for the above EXPORT macro to
-# work. You can do so with the 'cc_include' variable.
-# e.g. 'base/base_export.h'
-#
-# Implementation notes:
-# A proto_out_dir of foo/bar produces
-#   <(SHARED_INTERMEDIATE_DIR)/protoc_out/foo/bar/{file1,file2}.pb.{cc,h}
-#   <(SHARED_INTERMEDIATE_DIR)/pyproto/foo/bar/{file1,file2}_pb2.py
