+description: |
+  This directive creates a task which resides on the local node. It allocates
+  and initializes a TCB, a stack, and an optional floating point context area.
+  The mode parameter contains values which sets the task’s initial execution
+  mode. The RTEMS_FLOATING_POINT attribute should be specified if the created
+  task is to use a numeric coprocessor. For performance reasons, it is
+  recommended that tasks not using the numeric coprocessor should specify the
+  RTEMS_NO_FLOATING_POINT attribute. If the RTEMS_GLOBAL attribute is
+  specified, the task can be accessed from remote nodes. The task id, returned
+  in id, is used in other task related directives to access the task. When
+  created, a task is placed in the dormant state and can only be made ready to
+  execute using the directive rtems_task_start().
