damage

damage deals with DMG files, which are compressed little bundles of evil.

In particular, it should be able to:

• Give you information about a DMG file
  • Whether or not it has a SLA (Software License Agreement), for example
  • And extracting the text of said SLA
• Attach/detach a DMG file
  • Bypassing said SLA if you tell it to

Prerequisites

hdiutil must be in your $PATH.

That probably means being on macOS.
