+# CONFIG_START_YEAR, CONFIG_START_MONTH, CONFIG_START_DAY -
+#   Used to initialize the internal time logic.
+# CONFIG_GREGORIAN_TIME - Enables Gregorian time conversions.
+#   You would only need this if you are concerned about accurate
+#   time conversions in the past or in the distant future.
+# CONFIG_JULIAN_TIME - Enables Julian time conversions. You
+#   would only need this if you are concerned about accurate

+#   provides /dev/console.  Enables stdout, stderr, stdin.
+# CONFIG_DEV_LOWCONSOLE - Use the simple, low-level serial console
+#   driver (minimul support)
+# CONFIG_MUTEX_TYPES: Set to enable support for recursive and
+#   errorcheck mutexes. Enables pthread_mutexattr_settype().
+# CONFIG_PRIORITY_INHERITANCE : Set to enable support for priority
+#   inheritance on mutexes and semaphores. 
+# CONFIG_SEM_PREALLOCHOLDERS: This setting is only used if priority
+#   inheritance is enabled.  It defines the maximum number of
+#   different threads (minus one) that can take counts on a
+#   semaphore with priority inheritance support.  This may be 
+#   set to zero if priority inheritance is disabled OR if you
+#   are only using semaphores as mutexes (only one holder) OR
+#   if no more than two threads participate using a counting
+#   semaphore.
+# CONFIG_SEM_NNESTPRIO.  If priority inheritance is enabled,
+#   then this setting is the maximum number of higher priority
+#   threads (minus 1) than can be waiting for another thread
+#   to release a count on a semaphore.  This value may be set
+#   to zero if no more than one thread is expected to wait for
+#   a semaphore.
+# CONFIG_FDCLONE_DISABLE. Disable cloning of all file descriptors
+#   by task_create() when a new task is started.  If set, all
+#   files/drivers will appear to be closed in the new task.
+# CONFIG_FDCLONE_STDIO. Disable cloning of all but the first
+#   three file descriptors (stdin, stdout, stderr) by task_create()
+#   when a new task is started. If set, all files/drivers will
+#   appear to be closed in the new task except for stdin, stdout,
+#   and stderr.
+# CONFIG_SDCLONE_DISABLE. Disable cloning of all socket
+#   desciptors by task_create() when a new task is started. If
+#   set, all sockets will appear to be closed in the new task.
+# CONFIG_NXFLAT. Enable support for the NXFLAT binary format.
+#  This format will support execution of NuttX binaries located
+#  in a ROMFS filesystem (see examples/nxflat).
+# CONFIG_SCHED_WORKQUEUE.  Create a dedicated "worker" thread to
+#  handle delayed processing from interrupt handlers.  This feature
+#  is required for some drivers but, if there are not complaints,
+#  can be safely disabled.  The worker thread also performs
+#  garbage collection -- completing any delayed memory deallocations
+#  from interrupt handlers.  If the worker thread is disabled,
+#  then that clean will be performed by the IDLE thread instead
+#  (which runs at the lowest of priority and may not be appropriate
+#  if memory reclamation is of high priority).  If CONFIG_SCHED_WORKQUEUE
+#  is enabled, then the following options can also be used:
+# CONFIG_SCHED_WORKPRIORITY - The execution priority of the worker
+#  thread.  Default: 50
+# CONFIG_SCHED_WORKPERIOD - How often the worker thread checks for
+#  work in units of microseconds.  Default: 50*1000 (50 MS).
+# CONFIG_SCHED_WORKSTACKSIZE - The stack size allocated for the worker
+#  thread.  Default: CONFIG_IDLETHREAD_STACKSIZE.
+# CONFIG_SIG_SIGWORK - The signal number that will be used to wake-up
+#  the worker thread.  Default: 4
