What does it mean for a language to be called “[Tcl]”? It surely cannot just mean that it is built from [C] via libtcl; there must be something deeper than that. Well, the [Endecalogue]/[Dodekalogue] must have something to do with it of course, but is that all? I suspect not; you can't do anything without more than that. So on this page, [dkf%|%I]'m going to try to identify what additional things have to be there to make up something that we'd recognize as Tcl. In particular, I'm going to identify “''profile''s” that comprise a particular language core, related semantics and minimal associated set of commands; these profiles will build on top of each other of course.
