Gobo Eiffel, version 1.6 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. The software included in this package is copyrighted freeware distributed under the terms and conditions of the Eiffel Forum Freeware License as specified in file License.txt. 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, version 1.6 (gelex) . Gobo Eiffel Yacc, version 1.6 (geyacc) . Gobo Eiffel Preprocessor, version 1.6 (gepp) The software provided in this distribution should work on any platform where supported Eiffel compilers are available. However this software has only been tested under Windows NT. As a consequence, the directory separator used through out this distribution is \, following Windows convention. However, since most Eiffel compilers use the notation $NAME for environment variables in their Ace files (or equivalent), this convention has been used instead of the Windowish %NAME%. To install this package, copy the files to a directory of your choice on your disk and set the environment variable GOBO to that directory, known as the distribution directory. Also put the directory $GOBO\bin in your PATH. The supported Eiffel compilers, in alphabetical order, are: Halstenbach 3.0Beta 3, ISE Eiffel 4.5.020, SmallEiffel -0.76beta#4 (14 July 2000), Visual Eiffel 3.3b (Build 2300). For more details about the supported Eiffel compilers, please see the file "Release_notes.txt". This software might work with other Eiffel compilers and/or other compiler versions, however no test has been made. To have a better understanding of the way this software has been designed and implemented, you can also have a look at "$GOBO\doc\portability".

Documentation is also available on the Web at http://www.gobosoft.com/. Check it out regularly for updates, bug fixes, workarounds and new releases. You can also subscribe to the Gobo Eiffel mailing list (http://www.egroups.com/group/gobo-eiffel/) and take part to the discussions or ask your questions there. Although the license allows you to do pretty much whatever you want with this software, I would be grateful to get your feedbacks, bug reports and/or bug fixes, improvements, etc. so that others could benefit from your work and ideas as well. I would also be interested in hearing about your projects and how easy (or difficult) it was to adapt this software for your specific needs. Thank you in advance. -- Copyright (c) 1997-2000, Eric Bezault mailto:ericb@gobosoft.com http://www.gobosoft.com 20 August 2000
