Thinking more about this, I guess META.yml would need to provide a little more info to a configure module. Would something like the following work?
It's probably too late, but I am not keen on YAML. What is wrong with pure Perl configuration information? YAML is touchy about how it is formatted. Perl programmers will be reading this information and all Perl programmers already know Perl, so why fix what is not broken? Why force them to learn YAML?
