    <title>Command Explanations</title>

    <para><parameter>--libdir=/etc</parameter>: For some reason, the
    <command>configure</command> and <command>make</command> routine for
    <application>Lynx</application> uses <option>libdir</option> as the prefix
    for the configuration file. This is set to
    <filename class="directory">/etc</filename> so that the system wide
    configuration file is <filename>/etc/lynx.cfg</filename>.</para>

    <para><parameter>--with-zlib</parameter>: This enables support for
    linking <filename class="libraryfile">libz</filename> into
    <application>Lynx</application>.</para>

    <para><parameter>--with-bzlib</parameter>: This enables support for
    linking <filename class="libraryfile">libbz2</filename> into
    <application>Lynx</application>.</para>

    <para><parameter>docdir=... helpdir=...</parameter>: These
    variables are set to avoid getting the help and documentation files
    installed under <filename class="directory">/etc</filename>.</para>

        <para><parameter>install-full</parameter>: In addition to the standard
        installation, this target installs the documentation and the help
        files.</para>

    <para><option>--with-ssl</option>: This enables support for
    linking SSL into <application>Lynx</application>.</para>

    <para><option>--with-gnutls</option>: This enables support for
    linking <application>GnuTLS</application> into
    <application>Lynx</application>.</para>

    <para><command>chgrp -v -R root
    /usr/share/doc/lynx-&lynx-version;/doc</command>:
    This command corrects the improper group ownership of installed
    documentation files caused if <application>Lynx</application> is built
    by any user other than
    <systemitem class="username">root</systemitem>.</para>

    <note>
      <para>There has been a security vulnerability identified if you enable
      support for CGI links by passing the <option>--enable-cgi-links</option>
      parameter to <command>configure</command>. See <ulink
      url="http://seclists.org/lists/vulnwatch/2005/Oct-Dec/0041.html"/> for
