            -mmodule executes "use" module "();" before executing
            your program.

            -Mmodule executes "use" module ";" before executing
            your program.  You can use quotes to add extra code
            after the module name, e.g., '-Mmodule qw(foo bar)'.

            If the first character after the -M or -m is a dash
            ("-") then the 'use' is replaced with 'no'.

            A little builtin syntactic sugar means you can also
            say -mmodule=foo,bar or -Mmodule=foo,bar as a short-
            cut for '-Mmodule qw(foo bar)'.  This avoids the need
            to use quotes when importing symbols.  The actual
            code generated by -Mmodule=foo,bar is "use module
            split(/,/,q{foo,bar})".  Note that the "=" form
            removes the distinction between -m and -M.
