Version 0.1.4:

    2004-04-29:
    
        - Improved the layout and usability of python parser files generated
          by the bison2py utility, particularly with the '-c' option enabled

        - fixed the 'template' example, so that it actually works if used as is

        - tidied up and fleshed out the walkthrough document

Version 0.1.3:

    2004-04-28:
    
        - java example:
        
            - replaced grammar file with an adapted version of one
              from the GNU gcj compiler source - the damn thing works now!
              
            - fixed lex script

        - core - added support for a 'debug' flag keyword argument to Parser.run(),
          which causes the bison-generated parser to haemorrhage out all manner of
          detailed debug info

        - various other fixes and tidy-ups

Version 0.1.2:

    2004-04-25:

        - moved pure-python code from bison.pyx (now renamed to bison_.pyx),

        - patched by Eugene Oden to fix bug in processing legacy rules files
          in cases where rules contained character literals

          of handler code as separate node classes instead of methods
