setopt [ {+|-}options | {+|-}o option_name ] [ -m ] [ name ... ]
       Set the options for the shell.  All options specified either with
       flags or by name are set.

       If no arguments are supplied, the names of all options currently
       set are printed.  The form is chosen so as to minimize the
       differences from the default options for the current emulation
       (the default emulation being native zsh, shown as <Z> in
       zshoptions(1)).  Options that are on by default for the emulation
       are shown with the prefix no only if they are off, while other
       options are shown without the prefix no and only if they are on.
       In addition to options changed from the default state by the user,
       any options activated automatically by the shell (for example,
       SHIN_STDIN or INTERACTIVE) will be shown in the list.  The format
       is further modified by the option KSH_OPTION_PRINT, however the
       rationale for choosing options with or without the no prefix
       remains the same in this case.

       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.

       Note that a bad option name does not cause execution of subsequent
       shell code to be aborted; this is behaviour is different from that
       of `set -o'.  This is because set is regarded as a special builtin
       by the POSIX standard, but setopt is not.
