+    This formula does not install either `gpg` or `gpgv` executables into
+    the PATH.
+
+    If you simply require `gpg` and `gpgv` executables without explicitly
+    needing GnuPG 1.x we recommend:
+      brew install gnupg
+
+    If you really need to use these tools without the "1" suffix you can
+    add a "gpgbin" directory to your PATH from your #{shell_profile} like:
+
+        PATH="#{opt_libexec}/gpgbin:$PATH"
+
+    Note that doing so may interfere with GPG-using formulae installed via
+    Homebrew.
