    <para>The Bzip2 package does not contain a <command>configure</command>
    script. There are two <filename>Makefile</filename>, one for the shared
    library, and the other for the static library. Since we need both, We
    do the compilation in two stages. First the shared library:</para>

<screen><userinput remap="make">make -f Makefile-libbz2_so
make clean</userinput></screen>

      <title>The meaning of the make parameter:</title>

        <term><parameter>-f Makefile-libbz2_so</parameter></term>
        <listitem>
          <para>This will cause Bzip2 to be built using a different
          <filename>Makefile</filename> file, in this case the
          <filename>Makefile-libbz2_so</filename> file, which creates a dynamic
          <filename class="libraryfile">libbz2.so</filename> library and links
          the Bzip2 utilities against it.</para>

    <para>Compile and test the package with:</para>
