There are still undocumented options including exact_mirror. Here's the
full list as I see it.
Undocumented minicpan options.
-c / --class
-h / --help
-v / --version
-x
Undocumented CPAN::Mini options.
* exact_mirror
Also the keys of the .minicpanrc file are not documented. Presumably
they are the same as the options to CPAN::Mini but this is never said in
the minicpan docs.
