One of the main concerns of Gobo Eiffel is to provide you with Eiffel libraries and tools that are portable across various Eiffel compilers available on the market. That way, you can still use your favorite Eiffel compiler while taking advantage of the goodies included in this package. This package consists of five Eiffel libraries: Gobo Eiffel Kernel Library Gobo Eiffel Structure Library Gobo Eiffel Lexical Library Gobo Eiffel Parse Library Gobo Eiffel Utility Library and three utilities: Gobo Eiffel Lex (gelex) Gobo Eiffel Yacc (geyacc) Gobo Eiffel Preprocessor (gepp)
