setopt [ {+|-}options | {+|-}o option name ] [ name ... ]
       Set  the options for the shell.  All options speci-
       fied either with flags or by name are set.   If  no
       arguments  are  supplied,  the names of all options
       currently set are printed.  If the -m flag is given
       the  arguments  are taken as patterns (which should
       be quoted to preserve them from  being  interpreted
       as  glob  patterns),  and  all  options  with names
       matching these patterns are set.
