Eiffel source checker

A compiler front-end for Eiffel 3 by Olaf Langmack <langmack@inf.fu-berlin.de> and Burghardt Groeber. It was generated automatically with the Karlsruhe toolbox for compiler construction according to the most recent public language definition. The parser derives an easy-to-use abstract syntax tree, supports elementary error recovery and provides a precise source code indication of errors. It performs a strict syntax check and analyses 4000 lines of source code per second on a Sun SPARC workstation.
