    <para>
      <application>Lua</application> is a powerful light-weight programming
      language designed for extending applications. It is also frequently used
      as a general-purpose, stand-alone language. <application>Lua</application>
      is implemented as a small library of C functions, written in ANSI C, and
      compiles unmodified in all known platforms. The implementation goals are
      simplicity, efficiency, portability, and low embedding cost. The result is
      a fast language engine with small footprint, making it ideal in embedded
      systems too.
