Acknowledgements

       Marpa is directly derived from two other parsers.  The first was discovered by John Aycock
       and R.  Nigel Horspool and is described in their Aycock and Horspool 2002.  The second was
       discovered by Joop Leo and is described in Leo 1991.  Aycock, Horspool, and Leo, in turn,
       based their algorithms on the algorithm discovered by Jay Earley.  I combined the Aycock-
       Horspool algorithm with the Leo algorithm, and added significant changes of my own.

       I'm grateful to Randal Schwartz for his support over the years that I've been working on
       Marpa.  My chats with Larry Wall have been few and brief, but his openness to new ideas
       has been a major encouragement and his insight into the relationship between "natural
       language" and computer language has been a major influence.  More recently, Allison Randal
       and Patrick Michaud have been generous with their very valuable time.  They might have
       preferred that I volunteered as a Parrot cage-cleaner, but if so, they were too polite to
       say.

       Many at perlmonks.org answered questions for me.  I used answers from chromatic, Corion,
       dragonchild, jdporter, samtregar and Juerd, among others, in writing this module.  I'm
       just as grateful to those whose answers I didn't use.  My inquiries were made while I was
       thinking out the code and it wasn't always 100% clear what I was after.  If the butt is
       moved after the round, it shouldn't count against the archer.

       In writing the Pure Perl version of Marpa, I benefited from studying the work of Francois
       Desarmenien ("Parse::Yapp"), Damian Conway ("Parse::RecDescent") and Graham Barr
       ("Scalar::Util").  Adam Kennedy patiently instructed me in module writing, both on the
       finer points and on issues about which I really should have known better.

       I am very grateful to a handful of early contributors, whose contributions were made when
       I desperately needed help.  I am especially grateful to Ron Savage, who has been a very
       aggressive early adopter of all Marpa's versions.  Ruslan Zakirov generously started, and
       agreed to moderate, the "Marpa parser" mailing list.  Peter Stuifzand invented the
       "Stuifzand interface", which was the original inspiration for the SLIF.

       Ron, Peter and Ruslan Z. have since gone on to contribute in ways too numerous to mention,
       and others have joined in.  Jean-Damien Durand's numerous contributions include the
       Windows port of Marpa.  Ruslan Shvedov helped with ASF's and my documentation.  Andrew
       Rodland's TAP parser, with one Marpa grammar layered on another, was another major
       inspiration for the SLIF.

       Finally, my thanks to all those who participated on the "Marpa parser" mailing list.  It
       is hard to describe how important informed and constructive feedback is to a lone laborer
       on a complex and large project like Marpa, and I greatly appreciate all the contributors
       to the list.
