// Module Overview: Starboard Configuration module
//
// Provides a description of the current platform in lurid detail so that
// common code never needs to actually know what the current operating system
// and architecture are.
//
// It is both very pragmatic and canonical in that if any application code
// finds itself needing to make a platform decision, it should always define
// a Starboard Configuration feature instead. This implies the continued
// existence of very narrowly-defined configuration features, but it retains
// porting control in Starboard.

// inclusive.

// stable or frozen. Production-oriented ports should avoid declaring that they

// --- Experimental Feature Defines ------------------------------------------
// Note that experimental feature comments will be moved into
// starboard/CHANGELOG.md when released. Thus, you can find examples of the
// format your feature comments should take by checking that file.
// EXAMPLE:
// // Introduce new experimental feature.
// // Add a function, `SbMyNewFeature()` to `starboard/feature.h` which
// // exposes functionality for my new feature.
// #define SB_MY_EXPERIMENTAL_FEATURE VERSION SB_EXPERIMENTAL_API_VERSION

// enum to allow platform-specific User-Agent suffix.
