 > We don't list them all [such as --config-file] in the global --help so
 as not to clutter things, but then we need a way to let people know that
 there are extra global options and provide a way to get the help for them
 via some extended --help thing.

 Should go into a manual instead. You have already copied most of the good
 parts of the CPAN toolchain, installing man pages along binaries is one of
 the last things I am missing.
