[Module-build-general] META.yml extraction on CPAN

[<and...@an...>]

Autrijus suggested to me to start extracting the META.yml files as
we're doing for the README. So I did. The first yaml file has been
extracted for Casey West:

-rw-rw-r--    1 root     root          366 Mar 12 21:42 poest-0.20030312.readme
-rw-rw-r--    1 root     root          327 Mar 12 21:44 poest-0.20030312.meta
-rw-rw-r--    1 root     root        14014 Mar 12 21:46 poest-0.20030312.tar.gz

I realize now that META.yml should contain some protocol.version tag
so that the reader knows which fields he can expect. And a spec, what
the file contains and a revision history of the spec to know what a
specific file contains or should contain depending on
protocol.version. And a URL for the spec so that we can point to it.

OK, a subset of all this will do.

What do we have? What do you suggest?
