+/* NAME
+/*	qmqp-source 1
+/* SUMMARY
+/*	parallelized QMQP test generator
+/* SYNOPSIS
+/* .fi
+/*	\fBqmqp-source\fR [\fIoptions\fR] [\fBinet:\fR]\fIhost\fR[:\fIport\fR]
+/*
+/*	\fBqmqp-source\fR [\fIoptions\fR] \fBunix:\fIpathname\fR
+/* DESCRIPTION
+/*	\fBqmqp-source\fR connects to the named host and TCP port (default 628)
+/*	and sends one or more messages to it, either sequentially
+/*	or in parallel. The program speaks the QMQP protocol.
+/*	Connections can be made to UNIX-domain and IPv4 or IPv6 servers.
+/*	IPv4 and IPv6 are the default.
+/*
+/*	Note: this is an unsupported test program. No attempt is made
+/*	to maintain compatibility between successive versions.
+/*
+/*	Arguments:
+/* .IP \fB-4\fR
+/*	Connect to the server with IPv4. This option has no effect when
+/*	Postfix is built without IPv6 support.
+/* .IP \fB-6\fR
+/*	Connect to the server with IPv6. This option is not available when
+/*	Postfix is built without IPv6 support.
+/* .IP \fB-c\fR
+/*	Display a running counter that is incremented each time
+/*	a delivery completes.
+/* .IP "\fB-C \fIcount\fR"
+/*	When a host sends RESET instead of SYN|ACK, try \fIcount\fR times
+/*	before giving up. The default count is 1. Specify a larger count in
+/*	order to work around a problem with TCP/IP stacks that send RESET
+/*	when the listen queue is full.
+/* .IP "\fB-f \fIfrom\fR"
+/*	Use the specified sender address (default: <foo@myhostname>).
+/* .IP "\fB-l \fIlength\fR"
+/*	Send \fIlength\fR bytes as message payload. The length
+/*	includes the message headers.
+/* .IP "\fB-m \fImessage_count\fR"
+/*	Send the specified number of messages (default: 1).
+/* .IP "\fB-M \fImyhostname\fR"
+/*	Use the specified hostname or [address] in the default
+/*	sender and recipient addresses, instead of the machine
+/*	hostname.
+/* .IP "\fB-r \fIrecipient_count\fR"
+/*	Send the specified number of recipients per transaction (default: 1).
+/*	Recipient names are generated by prepending a number to the
+/*	recipient address.
+/* .IP "\fB-s \fIsession_count\fR"
+/*	Run the specified number of QMQP sessions in parallel (default: 1).
+/* .IP "\fB-t \fIto\fR"
+/*	Use the specified recipient address (default: <foo@myhostname>).
+/* .IP "\fB-R \fIinterval\fR"
+/*	Wait for a random period of time 0 <= n <= interval between messages.
+/*	Suspending one thread does not affect other delivery threads.
+/* .IP \fB-v\fR
+/*	Make the program more verbose, for debugging purposes.
+/* .IP "\fB-w \fIinterval\fR"
+/*	Wait a fixed time between messages.
+/*	Suspending one thread does not affect other delivery threads.
