Creating a "DMG installer" for OS X

A DMG Installer is convenient way to provide end-users a simple way to install an application bundle. They are basically a folder with a shortcut to the Applications directory but they can be customized with icons, backgrounds, and layout properties. A DMG file (.dmg) is a Mac OS X Disk Image file and it is used to package files or folders providing compression, encryption, and read-only to the package.

Attempt to phone home with a reverse ssh tunnel every time the OS X is booted. If ssh crashes or returns, then launchd will restart it in 10 seconds.

Assumptions:

• The user has a .ssh/config as described below
• The remote host key has been placed in user's known_hosts file
• A private ssh key is installed at /Users/user/.ssh/user-home-fwd
• The remote ssh host has the authorized keys file setup as described below

Place the file @ /Library/LaunchDaemons/phone.home.plist

"""strip outputs from an IPython Notebook

Opens a notebook, strips its output, and writes the outputless version to the original file.

Useful mainly as a git filter or pre-commit hook for users who don't want to track output in VCS.

This does mostly the same thing as the `Clear All Output` command in the notebook UI.
