   2 //
   3 // This list is used to generate RuntimeEnabledFeatures.h/cpp which contains
   4 // a class that stores static enablers for all experimental features.
   5 //
   6 // Each feature can be assigned a "status":
   7 // status=stable -> Enable this in all Blink configurations.  We are committed to these APIs indefinitely.
   8 // status=experimental -> In-progress features, Web Developers might play with, but are not on by default in stable.
   9 // status=test -> Enabled in ContentShell for testing, otherwise off.
  10 // status=deprecated -> Alias for "test", will be removed at some point.
  11 // Features without a status are not enabled anywhere by default.
  12 //
  13 // "implied_by" or "depends_on" specifies relationship to other features:
  14 // implied_by=feature1[,feature2,...] -> The feature is automatically enabled if any implied_by features is enabled;
  15 // depends_on=feature1[,feature2,...] -> The feature is enabled only if all depends_on features are enabled.
  16 // Only one of "implied_by" and "depends_on" can be specified.
  17 //
  18 // "stable" features listed here should be rare, as anything which we've shipped stable
  19 // can have its runtime flag removed soon after.
  20 //
  21 // condition=ENABLE_NAME is used for wrapping features in compile-time
  22 // #if ENABLE(FEATURE) guards.  These are deprecated and should all be removed.
