+/*++
+/* NAME
+/* postkick 1
+/* SUMMARY
+/* kick a Postfix service
+/* SYNOPSIS
+/* .fi
+/* \fBpostkick\fR [\fB-c \fIconfig_dir\fR] [\fB-v\fR]
+/* \fIclass service request\fR
+/* DESCRIPTION
+/* The \fBpostkick\fR(1) command sends \fIrequest\fR to the
+/* specified \fIservice\fR over a local transport channel.
+/* This command makes Postfix private IPC accessible
+/* for use in, for example, shell scripts.
+/*
+/* Options:
+/* .IP "\fB-c\fR \fIconfig_dir\fR"
+/* Read the \fBmain.cf\fR configuration file in the named directory
+/* instead of the default configuration directory.
+/* .IP \fB-v\fR
+/* Enable verbose logging for debugging purposes. Multiple \fB-v\fR
+/* options make the software increasingly verbose.
+/* .PP
+/* Arguments:
+/* .IP \fIclass\fR
+/* Name of a class of local transport channel endpoints,
+/* either \fBpublic\fR (accessible by any local user) or
+/* \fBprivate\fR (administrative access only).
+/* .IP \fIservice\fR
+/* The name of a local transport endpoint within the named class.
+/* .IP \fIrequest\fR
+/* A string. The list of valid requests is service-specific.
+/* DIAGNOSTICS
+/* Problems and transactions are logged to the standard error
+/* stream.
+/* ENVIRONMENT
+/* .ad
+/* .fi
+/* .IP \fBMAIL_CONFIG\fR
+/* Directory with Postfix configuration files.
+/* .IP \fBMAIL_VERBOSE\fR
+/* Enable verbose logging for debugging purposes.
+/* CONFIGURATION PARAMETERS
+/* .ad
+/* .fi
+/* The following \fBmain.cf\fR parameters are especially relevant to
+/* this program.
+/* The text below provides only a parameter summary. See
+/* \fBpostconf\fR(5) for more details including examples.
+/* .IP "\fBconfig_directory (see 'postconf -d' output)\fR"
+/* The default location of the Postfix main.cf and master.cf
+/* configuration files.
+/* .IP "\fBapplication_event_drain_time (100s)\fR"
+/* How long the \fBpostkick\fR(1) command waits for a request to enter the
+/* Postfix daemon process input buffer before giving up.
+/* .IP "\fBimport_environment (see 'postconf -d' output)\fR"
+/* The list of environment parameters that a privileged Postfix
+/* process will import from a non-Postfix parent process, or name=value
+/* environment overrides.
+/* .IP "\fBqueue_directory (see 'postconf -d' output)\fR"
+/* The location of the Postfix top-level queue directory.
+/* FILES
+/* /var/spool/postfix/private, private class endpoints
+/* /var/spool/postfix/public, public class endpoints
+/* SEE ALSO
+/* qmgr(8), queue manager trigger protocol
+/* pickup(8), local pickup daemon
