-    In order not to collide with macOS system binaries, the Plan 9 binaries have
-    been installed to #{opt_libexec}/bin.
-    To run the Plan 9 version of a command simply call it through the command
-    "9", which has been installed into the Homebrew prefix bin.  For example,
-    to run Plan 9's ls run:
-        # 9 ls
