+/* NAME
+/*	quote_flags 3
+/* SUMMARY
+/*	quote rfc 821/822 local part
+/* SYNOPSIS
+/*	#include <quote_flags.h>
+/*
+/*	int	quote_flags_from_string(const char *string)
+/*
+/*	const char *quote_flags_to_string(VSTRING *res_buf, int mask)
+/* DESCRIPTION
+/*	quote_flags_from_string() converts symbolic flag names into
+/*	the corresponding internal bitmask. This logs a warning and
+/*	returns zero if an unknown symbolic name is specified.
+/*
+/*	quote_flags_to_string() converts from internal bitmask to
+/*	the corresponding symbolic names. This logs a warning and
+/*	returns a null pointer if an unknown bitmask is specified.
+/*
+/*	Arguments:
+/* .IP string
+/*	Symbolic representation of a quote_flags bitmask, for
+/*	example: \fB8bitclean | bare_localpart\fR. The conversion
+/*	is case-insensitive.
+/* .IP res_buf
+/*	Storage for the quote_flags_to_string() result, which has
+/*	the same form as the string argument. If a null pointer is
+/*	specified, quote_flags_to_string() uses storage that is
+/*	overwritten with each call.
+/* .IP mask
+/*	Binary representation of quote_flags.
+/* DIAGNOSTICS
+/*	Fatal error: out of memory; or unknown bitmask name or value.
