Deprotect is a program that 'deprotects' Warcraft III maps that have been otherwise
protected via programs such as Heavy Locker or Extprotect. It is being
made so that people who want to learn from maps may do so, but also makes
sure that people cannot steal credit for work they haven't done.
Deprotect is no longer being developed, but you can read more about its history and download the latest version at the Deprotect project page.
