+                  Announcing :  PLY-2.3 (Python Lex-Yacc)
+
+                        http://www.dabeaz.com/ply
+
+I'm pleased to announce a significant new update to PLY---a 100% Python
+implementation of the common parsing tools lex and yacc.  PLY-2.3 is
+a minor bug fix release, but also features improved performance.
+
+If you are new to PLY, here are a few highlights:
+
+-  PLY is closely modeled after traditional lex/yacc.  If you know how 
+   to use these or similar tools in other languages, you will find
+   PLY to be comparable.
+
+-  PLY provides very extensive error reporting and diagnostic
+   information to assist in parser construction.  The original
+   implementation was developed for instructional purposes.  As
+   a result, the system tries to identify the most common types
+   of errors made by novice users.
+
+-  PLY provides full support for empty productions, error recovery,
+   precedence rules, and ambiguous grammars.
+
+-  Parsing is based on LR-parsing which is fast, memory efficient,
+   better suited to large grammars, and which has a number of nice
+   properties when dealing with syntax errors and other parsing 
+   problems. Currently, PLY can build its parsing tables using 
+   either SLR or LALR(1) algorithms. 
+
+-  PLY can be used to build parsers for large programming languages.
+   Although it is not ultra-fast due to its Python implementation,
+   PLY can be used to parse grammars consisting of several hundred
+   rules (as might be found for a language like C).  The lexer and LR
+   parser are also reasonably efficient when parsing normal
+   sized programs.
+
+More information about PLY can be obtained on the PLY webpage at:
