+/* NAME
+/*	hfrom_format 3
+/* SUMMARY
+/*	Parse a header_from_format setting
+/* SYNOPSIS
+/*	#include <hfrom_format.h>
+/*
+/*	int	hfrom_format_parse(
+/*	const char *name,
+/*	const char *value)
+/*
+/*	const char *str_hfrom_format_code(int code)
+/* DESCRIPTION
+/*	hfrom_format_parse() takes a parameter name (used for
+/*	diagnostics) and value, and maps it to the corresponding
+/*	code: HFROM_FORMAT_NAME_STD maps to HFROM_FORMAT_CODE_STD,
+/*	and HFROM_FORMAT_NAME_OBS maps to HFROM_FORMAT_CODE_OBS.
+/*
+/*	str_hfrom_format_code() does the reverse mapping.
+/* DIAGNOSTICS
+/*	All input errors are fatal.
+/* LICENSE
+/* .ad
