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.
