Ask HN: Package management system for dotfile components

If you look at the world of dotfiles, you see lots and lots and lots of people maintaining many configurations in their dot files. In some cases, a developer who has done a lot with dotfiles has dozens upon dozens of modifications and they have their own approach to modularizing their dotfiles. Many of those modifications may have come from other developers in the form of cut and paste snippets.

This all seems quite primitive relative to the best ways to share code and modules. With that in mind, is there anything like NPM/Bundler/CPAN/etc?
