If +module_name is not supplied then the name of the header file will be used, +with the first character capitalized. + +If the extension might need extra libraries, they should be included +here. The extension Makefile.PL will take care of checking whether +the libraries actually exist and how they should be loaded. +The extra libraries should be specified in the form -lm -lposix, etc, +just as on the cc command line. By default, the Makefile.PL will +search through the library path determined by Configure. That path +can be augmented by including arguments of the form B<-L/another/library/path> +in the extra-libraries argument. + +=head1 OPTIONS + +=over 5 + +=item B<-n> I<module_name> + +Specifies a name to be used for the extension, e.g., S<-n RPC::DCE> + +=item B<-f> + +Allows an extension to be created for a header even if that header is +not found in /usr/include. + +=item B<-c> + +Omit C<constant()> from the .xs file and corresponding specialised +C<AUTOLOAD> from the .pm file. + +=item B<-A> + +Omit all autoload facilities.
