+dnl Define macros to enable various features.
+dnl - Macro: CAIRO_ENABLE_* (ID, NAME, DEFAULT, COMMANDS)
+dnl
+dnl where:
+dnl
+dnl ID is the feature id, eg. "ft" for cairo_ft_...
+dnl NAME is the human-readable name of the feature, eg. "FreeType"
+dnl DEFAULT is the default state of the feature:
+dnl "no" for experimental backends, eg. your favorite new backend
+dnl "yes" for mandatory backends, eg. png
+dnl "auto" for other supported backends, eg. xlib
+dnl COMMANDS are run to check whether the feature can be enabled. Their
+dnl result may be cached, so user should not count on them being run.
+dnl They should set use_$(ID) to something other than yes if the
+dnl feature cannot be built, eg. "no (requires SomeThing)". It then
+dnl should also set $(ID)_REQUIRES/CFLAGS/LIBS/...
+dnl appropriately. Look at the macro definition for more details,
+dnl or ask if in doubt.
