14/9 (BB) Added finite state approximation of grammars.
Internally the conversion is done <tt>cfg -&gt; regular -&gt; fa -&gt; slf</tt>, so the
different printers can be used to check the output of each stage.
The new options are:
<dl>
<dt><tt>pg -printer=slf</tt></dt>
<dd>A finite automaton in the HTK SLF format.</dd>
<dt><tt>pg -printer=slf_graphviz</tt></dt>
<dd>The same FA as in SLF, but in Graphviz format.</dd>
<dt><tt>pg -printer=fa_graphviz</tt></dt>
<dd>An FA with labelled edges, instead of labelled nodes which SLF has.</dd>
<dt><tt>pg -printer=regular</tt></dt>
<dd>A regular grammar in a simple BNF.</dd>
</dl>

4/9 (AR) Added the option <tt>pg -printer=stat</tt> to show 4/9 (AR) Added the option <tt>pg -printer=stat</tt> to show
