+ Defines the module name to be used at the troff ``.TH`` output.
+
+ This argument is optional. If not specified, it will be filled

+
+ ``section``
+ Usually a numeric value from 0 to 9, but man pages also accept

+ ``manual``
+ Defaults to ``Kernel API Manual``.

+ The above controls the output of teh corresponding fields on troff
