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.
