+The executable in the 'Notarized' directory has been codesigned and notarized for use on OS X Catalina. At the time of writing, Apple intend that, starting in January 2020, only such notarized executables will be able to run, no matter what the owner of the computer thinks.
+
+Furthermore, it is presently impossible to staple the notarization to a single executable. So, the first time the executable runs, it will phone into Apple to check it is notarized.
