Last active January 3, 2016 00:19
Creating sub classes with prototype assigning directly will confuse instanceof operator.
var util = require('util')
function Class() {}
function SubClass() {}
function WrongSubClass() {}
util.inherits(SubClass, Class)
util.inherits(WrongSubClass, Class)

convert favicon-16.png favicon-32.png favicon-64.png -colors 256 -alpha background favicon.ico
