|
|
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
|
|
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.
