// A packet meter which measures the packet flow that is passing
// through and optionally attaches an ~EligibilityTimeTag to the packets. The
// tag contains the calculated simulation time when the packet becomes eligible
// for transmission according to the asynchronous shaper algorithm.
//
// This module is part of the asynchronous shaper infrastructure.
