h2xs

• http://search.cpan.org/~nwclark/perl-5.8.6/utils/h2xs.PL
• Originally written to create stub XS distributions from C header files
• Was used to create all stub distributions
• Was the only 'officially sanctioned' way of doing it

Problems

• Creates very basic files
• Lots of editing involved
• Creates files that are now out of date with the way most CPAN distributions are packaged
• Its verson of test.pl is not recommended any more
• Quite complex to know what options to use
