// 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.
#define SB_MINIMUM_API_VERSION 11

// The maximum API version allowed by this version of the Starboard headers,
// inclusive.

// stable or frozen. Production-oriented ports should avoid declaring that they
// implement the experimental Starboard API version.

// The next API version to be frozen, but is still subject to emergency
// changes. It is reasonable to base a port on the Release Candidate API
// version, but be aware that small incompatible changes may still be made to
// it.
// The following will be uncommented when an API version is a release candidate.
// #define SB_RELEASE_CANDIDATE_API_VERSION 13

// --- 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
