"Many thanks for LRSTAR.  I used to use flex/bison for my DSLs.  I'm working on a project which requires the fastest possible lexer/scanner for DSL (part of my web-server).  I can get it only with LRSTAR."
Sergey Kuritsin, PhD, Yekaterinburg, Russia

"LRSTAR seems quite professionally built. About parser and lexer speed, I'm literally impressed.  I'm finding this kind of parser generator suitable for parsers that I'm working on (high-speed server-side processing).  It works great, even on 64-bit machines with Linux and Mac OS X."
Vasko Mitanov, Software R&D Manager at Skopski Pazar, Romania

"I just happened upon your very-high quality lexer and parser generators.  Firstly, I'm really impressed with the capabilities.  I am finding LRSTAR particularly easy to use and quite powerful.  On my machine, I am getting an insane number of lines per second."
Bill Hart, PhD, Warwick University, UK

"I really like the LRSTAR tool (compared to yacc/bison).  I prefer the simplicity of LRSTAR.  I did a re-write using another parser generator, but the speed of their parser is at least an order of magnitude slower.  I am certain you have a good, maybe even a great, product."

"I'm not original author of this software but I can't contact Paul B Mann (original author). I decide to publish original code here since I feel that it's the best parser generator I've ever seen."

"Your LALR technology was used to build Lotus Script and we have over 50 million users now."
Kevin Jackson, Lotus Notes engineer.

"LALR 1.0 ... unbelievably fast and can handle huge grammars."
