/* NAME
/*	postconf_other 3
/* SUMMARY
/*	support for miscellaneous information categories
/* SYNOPSIS
/*	#include <postconf.h>
/*
/*	void	pcf_show_maps()
/*
/*	void	pcf_show_locks()
/*
/*	void	pcf_show_sasl(mode)
/*	int	mode;
/*
/*	void	pcf_show_tls(what)
/*	const char *what;
/* DESCRIPTION
/*	pcf_show_maps() lists the available map (lookup table)
/*	types.
/*
/*	pcf_show_locks() lists the available mailbox lock types.
/*
/*	pcf_show_sasl() shows the available SASL authentication
/*	plugin types.
/*
/*	pcf_show_tls() reports the "compile-version" or "run-version"
/*	of the TLS library, or the supported public-key algorithms.
/*
/*	Arguments:
/* .IP mode
/*	Show server information if the PCF_SHOW_SASL_SERV flag is
/*	set, otherwise show client information.
/* .IP what
/*	One of the literals "compile-version", "run-version" or
/*	"public-key-algorithms".
/* DIAGNOSTICS
/*	Problems are reported to the standard error stream.
