Unfortunately, being young and foolish, he released it under the GPL and now the GPL fans push it as the answer to life's ills even though its own author basically says it should be thought of as essentially a beta test product - but by the convoluted reasoning of GPL fans, byacc's license doesn't have enough restrictions to qualify as 'free'! But you can apparently still get it from a Gnu ftp server at.)Since it'll inevitably be recommended, I'll warn against using Bison. Bison was originally written by Robert Corbett, the same guy who later wrote Byacc, and he openly states that at the time he didn't really know or understand what he was doing. What you (probably want) are Flex 2.5.4 (some people are now 'maintaining' it and producing, but IMO they've done more to screw it up than fix any real shortcomings) and (likewise). (Edit 2017-11-17: Flex 2.5.4 is not available on Sourceforge any more, and the Flex github repository only goes back to 2.5.5.
