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 protect them from filename expansion),
       and  all options with names matching these patterns
       are set.
