+
+ 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:
