-// Field trials allow webrtc clients (such as Chrome) to turn on feature code
-// in binaries out in the field and gather information with that.
-//
-// WebRTC clients MUST provide an implementation of:
-//
-//   std::string webrtc::field_trial::FindFullName(const std::string& trial).
-//
-// Or link with a default one provided in:
-//
-//   system_wrappers/system_wrappers.gyp:field_trial_default
-//
-//
-// They are designed to wire up directly to chrome field trials and to speed up
-// developers by reducing the need to wire APIs to control whether a feature is
-// on/off. E.g. to experiment with a new method that could lead to a different
-// trade-off between CPU/bandwidth:
-//
-// 1 - Develop the feature with default behaviour off:
-//
-//   if (FieldTrial::FindFullName("WebRTCExperimenMethod2") == "Enabled")
-//     method2();
-//   else
-//     method1();
-//
-// 2 - Once the changes are rolled to chrome, the new code path can be
-//     controlled as normal chrome field trials.
-//
-// 3 - Evaluate the new feature and clean the code paths.
-//
-// Notes:
-//   - NOT every feature is a candidate to be controlled by this mechanism as
-//     it may require negotation between involved parties (e.g. SDP).
-//
-// TODO(andresp): since chrome --force-fieldtrials does not marks the trial
-//     as active it does not gets propaged to renderer process. For now one
-//     needs to push a config with start_active:true or run a local finch
-//     server.
-//
-// TODO(andresp): find out how to get bots to run tests with trials enabled.
