+# The patch does 3 things:
+#  - Depends on system lib for QtSingleApplication and QtLockedFile
+#  - Remove the extraneous namespace when calling QtSingleApplication
+#  - Fix a mismatch in the QtSingleApplication::messageReceived signal and the 
+# Application::slotParseMessage slot
+# These fix are needed because the system wide QtSingleApplication is slightly 
+# different from the bundled one.
