Reinvigorate a Perl project today

I contribute heavily in the Perl community, and I’m consistently impressed by the pains we take with code and assets that we personally have no interest in. There’s a group of Perl people who shepherd (camelherd?) code and projects that have lost their maintainers. I’m one of those people.

There’s a very simple system CPAN uses and which has been working since around 1994.
