EiffelStudio 5.3 for Linux

Admiral Akbar writes "It seems today is the release date of the best damn free IDE available today for Linux,EiffelStudio version 5.3, they have both a free and Enterprise version available. Why Eiffel's not classed as a mainstream language is beyond me, goodies include full concurrent engineering, amazing debugging, browsing and documentation facilities that even your dog would find easy use, plus a Mac OS X version is in the works with a beta available for download soon. Design by Contract here I come!"
