+Usage:
+Copy this file to your plugin's folder when you want to debug that plugin
+You should neither check this file into the plugin's version control system,
+nor distribute it in the final release.

+	-- The debugger will automatically put a breakpoint on this line, use this opportunity to set more breakpoints in your code
