At the moment, there is just
                    one back-end. On the front-end side, you will find three of them which are as
                    many state machine description languages, with many more possible. For potential
                    language writers, this document contains a <a class="link" href="ch06s02.html#internals-front-back-interface">description of the interface
                        between front-end and back-end</a>.</p><p>The first front-end is an adaptation of the example provided in the <a class="link" href="http://boostpro.com/mplbook" target="_top">MPL book</a> with actions
                    defined as pointers to state or state machine methods. The second one is based
                    on functors. The third, eUML (embedded UML) is an experimental language based on
                    Boost.Proto and Boost.Typeof and hiding most of the metaprogramming to increase
                    readability. Both eUML and the functor front-end also offer a functional library
                    (a bit like Boost.Phoenix) for use as action language (UML defining
                    none).</p></div></div><div class="navfooter"><hr><table width="100%" summary="Navigation footer"><tr><td width="40%" align="left"><a accesskey="p" href="ch02s03.html">Prev</a>&nbsp;</td><td width="20%" align="center"><a accesskey="u" href="pt01.html">Up</a></td><td width="40%" align="right">&nbsp;<a accesskey="n" href="ch03s02.html">Next</a></td></tr><tr><td width="40%" align="left" valign="top">State machine glossary&nbsp;</td><td width="20%" align="center"><a accesskey="h" href="index.html">Home</a></td><td width="40%" align="right" valign="top">&nbsp;Basic front-end</td></tr></table></div></body></html>
