      The instructions below automate the configuration process by piping
      <command>yes</command> to the <command>make config</command> command.
      If you wish to run the interactive configuration process (by changing
      the instruction to just <command>make config</command>), but you are
      not sure how to answer all the questions, then just accept the defaults.
      This will be just fine in the majority of cases. What you're asked here
      is a bunch of questions about which network protocols you've enabled
      in your kernel. The default answers will enable the tools from this
      package to work with the most common protocols: TCP, PPP, and several
      others. You still need to actually enable these protocols in the
      kernel&mdash;what you do here is merely tell the package to include
      support for those protocols in its programs, but it's up to the kernel
      to make the protocols available.
    </para>

    <note>
      <para>
        This package has several unneeded protocols and hardware device
        specific functions that are obsolete. To only build the minimum needed
        for your system, skip the <command>yes</command> command and answer
        each question interactively.  The minimum needed options are 'UNIX
        protocol family' and 'INET (TCP/IP) protocol family'.
