+/**
+	Provides vibe based applications with a central program entry point.
+
+	This module is included automatically through the import 'vibe.d'. It will provide a default
+	application entry point which parses command line arguments, reads the global vibe configuration
+	file, and starts the event loop.
+
+	The application itself then just has to initialize itself from within a 'static this' module
+	constructor and perform the appropriate calls to listen for connections or other operations.
+
+	If you want to provide your own main function, you have to import vibe.vibe instead of
+	vibe.d and define a -version=VibeCustomMain. Be sure to call vibe.core.core.runEventLoop
+	at the end of your main function in this case. Also beware that you have to make appropriate
+	calls to vibe.core.args.finalizeCommandLineOptions and vibe.core.core.lowerPrivileges to get the
+	same behavior.
