/**
* 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>
