I am not a Flex developer, but I doubt it, 
because the same question has some up a couple of 
times about Bison, and there, really nothing is 
available. The best way might be to read the 
sources and in books about lexer generator 
construction. For example, Flex uses a fairly 
standard two step regular expression -> NFA -> 
DFA construction. You might also ask in the 
newsgroup comp.compilers, and checking its FAQ, 
published there monthly. Also, the latest Flex 
versions, including CVS, are available at:
