-Seldom Used Configuration Parameters
-====================================
-
-This section describes configuration parameters supported by
-``<rtems/confdefs.h>`` which are seldom used by applications. These parameters
-tend to be oriented to debugging system configurations and providing
-work-arounds when the memory estimated by ``<rtems/confdefs.h>`` is incorrect.
