App::cpanoutofdate for keeping local::lib cpan up-to-date

A new version of App::cpanoutdated was released yesterday which ads a new -l and -L option to the bundled binary,cpan-outdated. These flags work the same as -l and -L in cpanminus, pointing to a local::lib controlled directory.

--compare-changes shows the difff to the changes file between releases. That's awesome.

This code will update all of the out of date modules in /apps/perl5 which is a local::lib controlled directory on my system: cpan-outdated -l /apps/perl5 | xargs cpanm -l /apps/perl5
