Fact: 8 out of 10 native node module packages published to npm are broken. Actual fact: npm has a library called pacote that handles resolving the package specifier you put in your dependencies to files on disk, and it's actually really nice. Change hak to use that library so now it's much simpler, handles versions correctly and supports git / github etc. urls so we can specify dependencies from git when a package author only publishes half of the package to npm.
