Files content
- scripts to copy over folders and files from upstream WebRTC project for APM and its dependencies.
- Copied files from upstream WebRTC project. For example: common_audio, modules, rtc_base and system_wrappers.
- webrtc_apm.cc/h C wrappers to access APM functions.

Update
To update this package to latest upstream WebRC:
- Run
./script/sync-apm.sh path/to/webrtc-checkout/src . emerge webrtc-apm to see if anything breaks.- If emerge success, then we're good.
- Otherwise look into the emerge failure, and then possibly:
- Update sync-apm.sh to copy more files if upstream directory structure changes.
- Update makefiles if upstream build files has changed.
- Update webrtc-apm ebuild file if dependencies changed.
- Create a new commit
