PLY is a Python-only implementation of the popular compiler construction
tools lex and yacc. The implementation borrows ideas from a number of 
previous efforts; most notably John Aycock's SPARK toolkit. However, 
the overall flavor of the implementation is more closely modeled after 
the C version of lex and yacc. The other significant feature of PLY is 
that it provides extensive input validation and error reporting--much 
more so than other Python parsing tools.
