      <title>Extra functionality for Berkeley DB in BLFS</title>

      <para>There are instructions to build this package in the BLFS
      book if you need to build the RPC server or additional language
      bindings. The additional language bindings will require additional
      packages to be installed. The BLFS instructions are located at
      <ulink url="&blfs-root;view/svn/server/databases.html#db"/> for
      suggested installation instructions.</para>
