-This directory contains the ObjectiveC implementation of the
-webrtc::PeerConnection API.  This can be built for Mac or iOS.  This
-file describes building the API, unit test, and AppRTCDemo sample app.
-
-Prerequisites:
-- Make sure gclient is checking out tools necessary to target iOS: your
-  .gclient file should contain a line like:
-  target_os = ['ios', 'mac']
-  Make sure to re-run gclient sync after adding this to download the tools.
-
-- Set up webrtc-related $GYP_DEFINES; example shell functions that set
-  up for building for iOS-device, iOS-simulator, and Mac (resp) are:
-function wrbase() {
-  cd /path/to/webrtc/src
-}
-
-function wrios() {
-  wrbase
-  export GYP_DEFINES="$GYP_DEFINES OS=ios"
-  export GYP_GENERATOR_FLAGS="$GYP_GENERATOR_FLAGS output_dir=out_ios"
-  export GYP_CROSSCOMPILE=1
-}
-
-function wrios32() {
-  wrios
-  export GYP_DEFINES="$GYP_DEFINES target_arch=arm"
-}
-
-function wrios64() {
-  wrios
-  export GYP_DEFINES="$GYP_DEFINES target_arch=arm64"
-}
-
-function wrsim() {
-  wrbase
-  export GYP_DEFINES="$GYP_DEFINES OS=ios target_subarch=arm32 target_arch=ia32"
-  export GYP_GENERATOR_FLAGS="$GYP_GENERATOR_FLAGS output_dir=out_sim"
-  export GYP_CROSSCOMPILE=1
-}
-
-function wrmac() {
-  wrbase
-  export GYP_DEFINES="$GYP_DEFINES OS=mac target_subarch=arm64 target_arch=x64"
-  export GYP_GENERATOR_FLAGS="$GYP_GENERATOR_FLAGS output_dir=out_mac"
-}
-
-- Finally, run "webrtc/build/gyp_webrtc.py" to generate ninja files.
-
-Example of building & using the unittest & app:
-
-- To build & run the unittest (must target mac):
-  wrmac && ./webrtc/build/gyp_webrtc.py && \
-      ninja -C out_mac/Debug libjingle_peerconnection_objc_test && \
-      ./out_mac/Debug/libjingle_peerconnection_objc_test.app/Contents/MacOS/libjingle_peerconnection_objc_test
-
-- To build & launch the sample app on OSX:
-  wrmac && ./webrtc/build/gyp_webrtc.py && ninja -C out_mac/Debug AppRTCDemo && \
-      ./out_mac/Debug/AppRTCDemo.app/Contents/MacOS/AppRTCDemo
-
-- To build & launch the sample app on the iOS simulator:
-  wrsim && ./webrtc/build/gyp_webrtc.py && ninja -C out_sim/Debug iossim AppRTCDemo && \
-      ./out_sim/Debug/iossim out_sim/Debug/AppRTCDemo.app
-
-- To build & sign the sample app for an iOS device (32 bit):
-  wrios32 && ./webrtc/build/gyp_webrtc.py && ninja -C out_ios/Debug-iphoneos AppRTCDemo
-
-- To build & sign the sample app for an iOS device (64 bit):
-  wrios64 && ./webrtc/build/gyp_webrtc.py && ninja -C out_ios/Debug-iphoneos AppRTCDemo
