* @short_description: Build configuration options
*
- * This describes the configuration options for GStreamer. When building
- * GStreamer there are a lot of parts (known internally as "subsystems" ) that can
- * be disabled for various reasons. The most common reasons are speed and size,
- * which is important because GStreamer is designed to run on embedded systems.
- *
- * If a subsystem is disabled, most of this changes are done in an API compatible
- * way, so you don't need to adapt your code in most cases. It is never done in an
- * ABI compatible way though. So if you want to disable a suybsystem, you have to
- * rebuild all programs depending on GStreamer, too.
