Re the '>>' line: AFAIK, TeX was developed before SGML existed; XML is derived from SGML (not sure it's strictly a subset), maybe that's '>>' meant to write. As for the '>' line, the first version of TeX was implemented in SAIL, which was an Algol-like programming language. The current version is written in WEB, which is a Pascal-based system + documentation; it is often converted to C for compilation. And TeX itself doesn't look anything like LISP to me, but maybe I'm missing s.t.? (Like a CAR and a CDR and...) Can someone enlighten me/us here?
