Eweasel

EiffelWeasel, also known as eweasel, is a tool originally written by David Hollenberg from Mosis (Information Sciences Institute - USC) in the early 1990's when the first Eiffel 3 compiler was released. The tool's goal was to ensure conformance of the ISE Eiffel compiler to the recently published specification and to detect any unforeseen regression from version to version.
