/**

 * SECTION:gstconfig

 * @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.

 *

 * If a subsystem is disabled in GStreamer, a value is defined in

 * <gst/gst.h>. You can check this if you do subsystem-specific stuff.

 * <example id="example-gstconfig">

 * <title>Doing subsystem specific things</title>

 * <programlisting>

 * &hash;ifndef GST_DISABLE_GST_DEBUG

 * // do stuff specific to the debugging subsystem

 * &hash;endif // GST_DISABLE_GST_DEBUG

 * </programlisting>

 * </example>
