+The special parameter C<argv>, if specified should point to an array
+reference with an array to use instead of C<@ARGV>.
+
+The paramater C<disable_gld>, if specified and a true value will disable
+the use of L<Getopt::Long::Descriptive> .
+
If L<Getopt::Long/GetOptions> fails (due to invalid arguments),
C<new_with_options> will throw an exception.
+If L<Getopt::Long::Descriptive> is installed and any of the following
+command line params are passed, the program will exit with usage
+information. You can add descriptions for each option by including a
+B<documentation> option for each attribute to document.
+
+ --?
+ --help
+ --usage
+
If you have L<Getopt::Long::Descriptive> a the C<usage> param is also passed to
C<new>.
This returns the role meta object.
