Create DMG From Applications with create-dmg [Mac]

While inbuilt hdutil can create a dmg from app folder (Appname.app), it can’t easily be used in scripts since it requires authentications.

Fortunately, create-dmg is a beatiful little free command-line tool by awesome Sindresorhus who publishes cool little apps for Mac!
