+DMG DJ incorporates an unmodified 2007 version of NDResourceFork by Nathan Day
+<https://github.com/nathanday/>. This package had its own license with a credit clause for source
+distributions. I've reproduced the license text here from an archive copy found at
+<https://web.archive.org/web/20111227061959/http://homepage.mac.com/nathan_day/pages/source.xml>:
+
+Some of the source code I've written is available for other developers to use, there are really no restrictions on use of this code other than leave my name (Nathan Day) within the source code,
+especially if you make your source code public with my code in it. Though the code has been tested
+and is in use, you use it at your own risk. Some of the features that have been put in are for
+future use and so have not been as rigorously tested as actually used features. If you find any
+bugs or have any problems with any of the code then feel free to contact me <[email protected]>.

+
+This was originally developed to play Blizzard's Starcraft, Brood War, and Warcraft III
+single-player campaigns from disc images, long before Blizzard released official no-CD patches,
+but should work for other applications as well.
+
+## Requirements
+
+Mac OS X 10.4+. Built as a universal binary.
+
+## Usage
+
+Open the app. Drag applications you want to manage into the "Applications" list on the left.
+Drag disc images for those applications into the "Associated disc images" list on the right.
+Click the "Load" checkbox to make a given app load a given image. The arrow buttons under each list
+should reveal the selected app or disc image in the Finder.
+
+## Notes
+
+I wrote this in 2007 and have resurrected it onto Github for historical interest only.
+Not sure if it'll even still compile with modern versions of Xcode, but fortunately, I do have
+an old build as well as the source. Check the Releases tab.
