/* 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.
