+.TH initlog 8 "Sun Jan 24 1999"
+.SH NAME
+initlog \- log messages and events to the system logger
+.SH SYNOPSIS
+.B initlog
+[\-cefnpqrs] [\-\-cmd=ARG] [\-\-event=ARG] [\-\-facility=ARG]
+[\-\-name=ARG] [\-\-priority=ARG] [\-\-run=ARG] [\-\-string=ARG]
+.SH DESCRIPTION
+\fBinitlog\fR logs messages and events to the system logger.
+It is mainly designed for use in init scripts. initlog
+reads a configuration file
+.I /etc/initlog.conf
+by default, to determine its settings. Any line preceded with a
+.I #
+is a comment, and the following configuration directives
+are recognized:
+.TP
+.I facility <logging facility>
+Sets the default logging facility
+.TP
+.I priority <logging priority>
+Sets the default logging priority
+.TP
+.I ignore <regexp>
+Messages that match the regular expression will not be logged.
+.TP
+initlog behavior can also be configured by command-line options.
+
+.SS OPTIONS
+.TP
+.I "\-c, \-\-cmd=[program]"
+Execute the specified program, logging anything output to
+stdout or stderr.
+.TP
+.I "\-e, \-\-event=[number]"
+Logs that the specified event happened. Used in conjuction
+with \fB\-\-name\fR. Currently specified events are:
+.PD 0
+.RS 8n
+.TP 3n
+.B 1
+the action completed successfully
+.TP
+.B 2
+the action failed
+.TP
+.B 3
+the action was cancelled at user request
+.TP
+.B 4
+the action failed due to the failure of a dependent action
+.RE
+.PD
+.TP
+.I "\-f, \-\-facility=[facility]"
+Log at the specified syslog facility. The default
+is \fBdaemon\fR (see syslog(3)).
+.TP
+.I "\-n, \-\-name=[string]"
+Log the event under the specified string, such as
+"inetd".
+.TP
+.I "\-p, \-\-priority=[priority]"
+Log at the specified syslog priority. The default
+is \fBnotice\fR (see syslog(3)).
+.TP
+.I "\-q"
+Do not print the program's output, unless it exits
+with a non-zero exit code.
+.TP
+.I "\-r, \-\-run=[program]"
+Execute the specified program, with an open file
+descriptor so that the program can pass back
+commands to initlog.
+.TP
+.I "\-s, \-\-string=[string]"
+Log the specified string to the logger.
+.TP
+.I "\-\-conf=[file]"
+Specifies an alternate configuration file.
+.SH FILES
+.I /etc/initlog.conf
+.SH "SEE ALSO"
+syslog(3), logger(1)
