-dnl Perform a check for a feature for GStreamer
-dnl Richard Boulton <richard-alsa@tartarus.org>
-dnl Thomas Vander Stichele <thomas@apestaart.org> added useful stuff

-dnl                   DEPENDENT-PLUGINS, TEST-FOR-FEATURE,
-dnl                   DISABLE-BY-DEFAULT, ACTION-IF-USE, ACTION-IF-NOTUSE)
-dnl
-dnl This macro adds a command line argument to enable the user to enable
-dnl or disable a feature, and if the feature is enabled, performs a supplied
-dnl test to check if the feature is available.
-dnl
-dnl The test should define HAVE_<FEATURE-NAME> to "yes" or "no" depending
-dnl on whether the feature is available.
-dnl
-dnl The macro will set USE_<FEATURE-NAME> to "yes" or "no" depending on
-dnl whether the feature is to be used.
-dnl Thomas changed this, so that when USE_<FEATURE-NAME> was already set
-dnl to no, then it stays that way.
-dnl
-dnl The macro will call AM_CONDITIONAL(USE_<<FEATURE-NAME>, ...) to allow
-dnl the feature to control what is built in Makefile.ams.  If you want
-dnl additional actions resulting from the test, you can add them with the
-dnl ACTION-IF-USE and ACTION-IF-NOTUSE parameters.
-dnl 
-dnl FEATURE-NAME        is the name of the feature, and should be in
-dnl                     purely upper case characters.
-dnl FEATURE-DESCRIPTION is used to describe the feature in help text for
-dnl                     the command line argument.
-dnl DEPENDENT-PLUGINS   lists any plugins which depend on this feature.
-dnl TEST-FOR-FEATURE    is a test which sets HAVE_<FEATURE-NAME> to "yes"
-dnl                     or "no" depending on whether the feature is
-dnl                     available.
-dnl DISABLE-BY-DEFAULT  if "disabled", the feature is disabled by default,
-dnl                     if any other value, the feature is enabled by default.
-dnl ACTION-IF-USE       any extra actions to perform if the feature is to be
-dnl                     used.
-dnl ACTION-IF-NOTUSE    any extra actions to perform if the feature is not to
-dnl                     be used.
