3.12 +dnl This macro adds a command line argument to enable the user to enable
3.13 +dnl or disable a feature, and if the feature is enabled, performs a supplied
3.14 +dnl test to check if the feature is available.
3.15 +dnl
3.16 +dnl The test should define HAVE_<FEATURE-NAME> to "yes" or "no" depending
3.17 +dnl on whether the feature is available.
3.18 +dnl
3.19 +dnl The macro will set USE_<FEATURE-NAME> to "yes" or "no" depending on

3.21 +dnl Thomas changed this, so that when USE_<FEATURE-NAME> was already set
3.22 +dnl to no, then it stays that way.
3.23 +dnl
3.24 +dnl The macro will call AM_CONDITIONAL(USE_<<FEATURE-NAME>, ...) to allow
3.25 +dnl the feature to control what is built in Makefile.ams. If you want
3.26 +dnl additional actions resulting from the test, you can add them with the
3.27 +dnl ACTION-IF-USE and ACTION-IF-NOTUSE parameters.
3.28 +dnl
3.29 +dnl FEATURE-NAME is the name of the feature, and should be in

3.31 +dnl FEATURE-DESCRIPTION is used to describe the feature in help text for
3.32 +dnl the command line argument.
3.33 +dnl DEPENDENT-PLUGINS lists any plugins which depend on this feature.
3.34 +dnl TEST-FOR-FEATURE is a test which sets HAVE_<FEATURE-NAME> to "yes"
3.35 +dnl or "no" depending on whether the feature is
3.36 +dnl available.
