+/* NAME
+/*	name_code 3
+/* SUMMARY
+/*	name to number table mapping
+/* SYNOPSIS
+/*	#include <name_code.h>
+/*
+/*	typedef struct {
+/* .in +4
+/*		const char *name;
+/*		int code;
+/* .in -4
+/*	} NAME_CODE;
+/*
+/*	int	name_code(table, flags, name)
+/*	const NAME_CODE *table;
+/*	int	flags;
+/*	const char *name;
+/*
+/*	const char *str_name_code(table, code)
+/*	const NAME_CODE *table;
+/*	int	code;
+/* DESCRIPTION
+/*	This module does simple name<->number mapping. The process
+/*	is controlled by a table of (name, code) values.
+/*	The table is terminated with a null pointer and a code that
+/*	corresponds to "name not found".
+/*
+/*	name_code() looks up the code that corresponds with the name.
+/*	The lookup is case insensitive. The flags argument specifies
+/*	zero or more of the following:
+/* .IP NAME_CODE_FLAG_STRICT_CASE
+/*	String lookups are case sensitive.
+/* .PP
+/*	For convenience the constant NAME_CODE_FLAG_NONE requests
+/*	no special processing.
+/*
+/*	str_name_code() translates a number to its equivalent string.
+/* DIAGNOSTICS
+/*	When the search fails, the result is the "name not found" code
+/*	or the null pointer, respectively.
+/* LICENSE
