[justinfagnani]

files seems to be generally prefered over .npmignore. I believe the files array can exclude paths with a ! prefix. Could we do the same by adding "!lib/demo" and "!lib/test"?

[usergenic]

@justinfagnani You're right and it is way cleaner and easier to maintain. After confirming it works I've removed the .npmignore in favor of just using files to manage the npm published contents.
