- * NAME is a single word descriptive identifier for the option.  This is the
- * token to pass in to the STRESS() macro at the sites where exectution is to
- * be controlled by the option.
- *
- * DESCRIPTION is a quoted string that should describe to a person unfamiliar
- * with the detailed internals of the code what behavior the option affects.
- *
- * RECOMMENDED is a suggested value for a person unfamiliar with the internals.
- * It should put reasonable stress on the system without crippling it.
- *
- * MIN and MAX are the minimum and maximum values allowed for the option.
- *
- * DEFAULT is the default value for the option.  Specify 0 to disable the
- * option by default, which should be the usual choice.  But some options can
- * be left on at low levels without noticeable impact to the end user.  An
- * example would be failing to allocate a buffer for every 100000th packet
- * processed by the system.
