Metalexer was developed to fulfill the need for a lexer generator that was modular and could be used naturally in extensible toolkits (like McLab and abc).
SableCC was started as the M.Sc. research project of Etienne Gagnon. Etienne is now a professor at UQAM and continued the development. His current web site is http://sablecc.org.
