+/* NAME
+/*	mail_task 3
+/* SUMMARY
+/*	set task name for logging purposes
+/* SYNOPSIS
+/*	#include <mail_task.h>
+/*
+/*	const char *mail_task(argv0)
+/*	const char *argv0;
+/* DESCRIPTION
+/*	mail_task() enforces consistent naming of mailer processes.
+/*	It strips pathname information from the process name, and
+/*	prepends the name of the mail system so that logfile entries
+/*	are easier to recognize. The mail system name is specified
+/*	with the "syslog_name" configuration parameter.
+/*
+/*	The result is overwritten with each call.
+/*
+/*	A null argv0 argument requests that the current result is
+/*	returned, or "unknown" when no current result exists.
+/* LICENSE
+/* .ad
+/* .fi
+/*	The Secure Mailer license must be distributed with this software.
