  • I Really consider this software the perfect program I ever tried! => consider having a look at this webiste for Free Gift Cards : www.fregifts.com

  • Been using Eiffel for a little over 3 years now for my hobby project, running on Linux. The more I use it, the more I like it, hands down the best general purpose language out there. EiffelStudio is a good IDE as well.

  • Language is the best to none. Although the IDE is a little outdated. I would like to see the IDE implemented with SCOOP for concurrency. And GUI development seems hard to me without GUI Builder.

  • I love Eiffel, I used it at work to produce a medical pump, and use it at home on my Gnu/Linux laptop. However I also wish to use it at work, a school, with the kids, On MS-windows. The teachers do not have access to admin passwords, and the msi installer is insisting on admin privileges, even when I try to install to a non privileged directory. I tried the zip version, I can unzip it but can not get it to work. I have searched but find no useful instructions. There is an install.readme in the zip, but it point to a web page telling us how to install the msi.

  • Wow, the Eiffel language is the best language I have ever seen. It is simple, powerful, elegant and more. Also, Eiffel coding with EiffelStudio make it even more perfect.
