/**
* SECTION:gstversion
* @short_description: GStreamer version macros.
*
* Use the GST_VERSION_* macros e.g. when defining own plugins. The GStreamer
* runtime checks if these plugin and core version match and refuses to use a
* plugin compiled against a different version of GStreamer.
* You can also use the macros to keep the GStreamer version information in
* your application.
*
* Use the gst_version() function if you want to know which version of
* GStreamer you are currently linked against.
*
* The version macros get defined by including "gst/gst.h".
