% File il2code.tex (original name extcode.tex changed in August 1996) does:
% (0) sets \czech, \slovak to ISO-8859-2 encoded hyphen-pattern numbers,
% (1) sets \catcode, \l/uccode for characters (code ISO-8859-2),
% (2) defines \csaccents for new behavior of \v, \', etc (code ISO-8859-2),
% (3) defines some \sequences for special cs-fonts characters.

% Created by Petr Olsak <olsak@math.feld.cvut.cz>, April, 1995
% September 1996: Better definition of \clqq and friends and \ogonek.
