title: Erlang, yecc and EBNF
body: <p>I want to implement a lexer and parser in Erlang.  The Erlang docs talk about <a href="http://erlang.org/doc/man/yecc.html" rel="nofollow">yecc</a> and <a href="http://erlang.org/doc/man/leex.html" rel="nofollow">leex</a> which should be incredibly helpful.  However, the yecc doc only mentions support for BNF grammar notation, not <a href="http://www.garshol.priv.no/download/text/bnf.html#id2.3." rel="nofollow">EBNF</a>.</p>
  
  <p>I'd like to use EBNF if I can help it though I can't find any documentation as to whether Erlang's yecc support EBNF.  Does it?</p>
