/* NAME
/*	exp_prop 3
/* SUMMARY
/*	address extension propagation control
/* SYNOPSIS
/*	#include <exp_prop.h>
/*
/*	int	ext_prop_mask(param_name, pattern)
/*	const char *param_name;
/*	const char *pattern;
/* DESCRIPTION
/*	This module controld 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.
/* DIAGNOSTICS
/*	Panic: inappropriate use.
