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.
