NAME
       Marpa::R2::Acknowledgements - Marpa acknowledgements


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.
