Todo:

    * dhcpd.conf file parser should understand semantics of
      configuration directives.
    * Better use of autoconfig. Author admits to be beginer in
      using auto tools. Help needed.
    * Bad english to good english translation for all files that
      author has touched. Help needed.
    * Threshold values -> alarm possibility.
    * Bug perhaps not? ./dhcpd-pools -o /dev/null
      /dev/null: Inappropriate ioctl for device
      Reason is fclose (outfile); in src/output.c

    @ version 3.x - tcp server & snmp support etc

    * TCP server / client for distant queries + libwrap support
      and some kind of protocol.
    * SNMP support. Program should be demon which gives states of
      pools almost instantly when queried. Calculations should be
      done periodically. This way huge dhcp lease files will not
      cause problem. Perhaps one thread could poll some socket
      waiting for query and mean while other could do periodical
      calculations, where output would be copying data for socket
      thread.
    * Configuration file for this command.
