I don't think readPkg works if there's no name, but in any event if there's no name we should just exit early with an error rather than default a name.

This is a way to solve the output issue for sure, but really the scope is part of the package name and so this is fixing it in the wrong place. I think we should probably just fix this where the files are actually written, here and here. Indeed, as you pointed out in chat, the -o,--out <prefix> option is broken so those two lines should be changed to use opts.out instead of pkg.name altogether, fixing two bugs in one PR. We should obviously fix the default of that option by popping off just the package name. That oughta do it.

Solid PR, thanks!

This works great – thanks! I'll release 0.4.1, and add tests in a later PR.
