      The Network Security Services (<application>NSS</application>) package is
      a set of libraries designed to support cross-platform development of
      security-enabled client and server applications. Applications built with
      NSS can support SSL v2 and v3, TLS, PKCS #5, PKCS #7, PKCS #11, PKCS #12,
      S/MIME, X.509 v3 certificates, and other security standards. This is
      useful for implementing SSL and S/MIME or other Internet security
      standards into an application.

      <!-- the unittest files get compiled automatically since nss-3.31.0 -->
      <!-- The unit tests were run during the build.-->
      To run the tests, execute the following commands:
    </para>

<screen remap="test"><userinput>cd tests &amp;&amp;
HOST=localhost DOMSUF=localdomain ./all.sh &amp;&amp;
cd ../</userinput></screen>
    
    <!--   Some information about the tests:
         - HOST=localhost and DOMSUF=localdomain require the changes done to
           /etc/hosts in r11892 (LFS). Without these variables, a FQDN is
           required to specified, and this generic way should work for
           everyone.
         - With NSS-3.53, there were 53,866 tests. The tests take an
           extremely long time to run. 
         - Another interesting discovery has to do with interrupting the tests.
           It was discovered that, when interrupting the tests, the test suite
           fails to spin down test servers that are run. This leads to an
           infinite loop in the tests where the test suite tries to kill a server
           that doesn't exist anymore because it pulls the wrong PID.
         - Test suite results (in HTML format!) can be found at 
           ../../test_results/security/localhost.1/

    <para>
      <parameter>BUILD_OPT=1</parameter>: This option is passed to
      <command>make</command> so that the build is performed with no debugging
      symbols built into the binaries and the default compiler optimizations are
      used.
    </para>

    <para>
      <parameter>NSPR_INCLUDE_DIR=/usr/include/nspr</parameter>: This option
      sets the location of the nspr headers.
    </para>

    <para>
      <parameter>USE_SYSTEM_ZLIB=1</parameter>: This option is passed to
      <command>make</command> to ensure that the
      <filename class="libraryfile">libssl3.so</filename> library is linked to
      the system installed <application>zlib</application> instead of the
      in-tree version.
    </para>

    <para>
      <parameter>ZLIB_LIBS=-lz</parameter>: This option provides the
      linker flags needed to link to the system <application>zlib</application>.
    </para>

    <para>
      <command>$([ $(uname -m) = x86_64 ] &amp;&amp; echo USE_64=1)</command>:
      The <parameter>USE_64=1</parameter> option is <emphasis>required on
      x86_64</emphasis>, otherwise <command>make</command> will try (and fail)
      to create 32-bit objects. The [ $(uname -m) = x86_64 ] test ensures it
      has no effect on a 32 bit system.
    </para>

    <para>
      <command>([ -f /usr/include/sqlite3.h ] &amp;&amp; echo
      NSS_USE_SYSTEM_SQLITE=1)</command>: This tests if
      <application>sqlite</application> is installed and if so it
      <command>echo</command>s the option NSS_USE_SYSTEM_SQLITE=1 to
      <command>make</command> so that
      <filename class="libraryfile">libsoftokn3.so</filename> will link against
      the system version of sqlite.
    </para>

    <para>
      <option>NSS_DISABLE_GTESTS=1</option>: If you don't need to run
      NSS test suite, append this option to <command>make</command> command,
      to prevent the compilation of tests and save some build time.
