+/* NAME
+/*	ext_prop 3
+/* SUMMARY
+/*	address extension propagation control
+/* SYNOPSIS
+/*	#include <ext_prop.h>
+/*
+/*	int	ext_prop_mask(param_name, pattern)
+/*	const char *param_name;
+/*	const char *pattern;
+/* DESCRIPTION
+/*	This module controls address extension propagation.
+/*
+/*	ext_prop_mask() takes a comma-separated list of names and
+/*	computes the corresponding mask. The following names are
+/*	recognized in \fBpattern\fR, with the corresponding bit mask
+/*	given in parentheses:
+/* .IP "canonical (EXT_PROP_CANONICAL)"
+/*	Propagate unmatched address extensions to the right-hand side
+/*	of canonical table entries (not: regular expressions).
+/* .IP "virtual (EXT_PROP_VIRTUAL)"
+/*	Propagate unmatched address extensions to the right-hand side
+/*	of virtual table entries (not: regular expressions).
+/* .IP "alias (EXT_PROP_ALIAS)"
+/*	Propagate unmatched address extensions to the right-hand side
+/*	of alias database entries.
+/* .IP "forward (EXT_PROP_FORWARD)"
+/*	Propagate unmatched address extensions to the right-hand side
+/*	of .forward file entries.
+/* .IP "include (EXT_PROP_INCLUDE)"
+/*	Propagate unmatched address extensions to the right-hand side
+/*	of :include: file entries.
+/* .IP "generic (EXT_PROP_GENERIC)"
+/*	Propagate unmatched address extensions to the right-hand side
+/*	of smtp_generic_maps entries.
+/* DIAGNOSTICS
+/*	Panic: inappropriate use.
