/* NAME
/*	qmgr_move 3
/* SUMMARY
/*	move queue entries to another queue
/* SYNOPSIS
/*	#include "qmgr.h"
/*
/*	void	qmgr_move(from, to, time_stamp)
/*	const char *from;
/*	const char *to;
/*	time_t	time_stamp;
/* DESCRIPTION
/*	The \fBqmgr_move\fR routine scans the \fIfrom\fR queue for entries
/*	with valid queue names and moves them to the \fIto\fR queue.
/*	If \fItime_stamp\fR is non-zero, the queue file time stamps are
/*	set to the specified value.
/*	Entries with invalid names are left alone. No attempt is made to
/*	look for other badness such as multiple links or weird file types.
/*	These issues are dealt with when a queue file is actually opened.
