SYNOPSIS

       This is a custom attribute metaclass trait which can be used to specify a the specific command line flag
       to use instead of the default one which MouseX::Getopt will create for you.

       cmd_flag
           Changes  the  commandline  flag  to  be  this value, instead of the default, which is the same as the
           attribute name.

       cmd_aliases
           Adds more aliases for this commandline flag, useful for short options and such.
