 <p>
 
+20/6 (AR) Added the command <tt>visialize_tree</tt> = <tt>vt</tt>, to
+display syntax trees graphically. Like <tt>vg</tt>, this command uses
+GraphViz and Ghostview. The foremost use is to pipe the parser to this
+command.

 10/6 (AR) Preprocessor of <tt>.gfe</tt> files can now be performed as part of
 any grammar compilation. The flag <tt>-ex</tt> causes GF to look for
 the <tt>.gfe</tt> files and preprocess those that are younger
