automate creation of the macos DMG images

[Antoine Martin]

Currently this is a manual (tedious) process, documented here: ​http://www.wikihow.com/Make-a-DMG-File-on-a-Mac and here:
​http://mac101.net/content/how-to/how-to-create-dmg-art-for-fancy-application-installations/comment-page-1/ and here:
​How to create a custom dmg installer on mac

But there must be a better way, maybe one of these can help:
