The idea is that you could always deliver a system (or a system + dependencies) in either one file (.fasl) or two files (.fasl and .so), depending on whether you're on ECL or another implementation. —♯ƒ • François-René ÐVB Rideau •Reflection&Cybernethics• http://fare.tunes.org The Constitution may not be perfect, but it's a lot better than what we've got!
