% Usage:
%
% Run iniTeX on this file. Do not try to use plain-TeX or LaTeX.
% Needs the font metric files: cmr10.tfm, cmti10.tfm
%
%
% Changes:
%
% 95/12/05 v1.0
% - initial version
% 95/12/06 v1.1
% - don't show tracing output
% - \nonstopmode and additional test for bug 2.
% 95/12/07 v1.2
% - added MLTeX version numbers (and release dates)
% - added test for MLTeX version 2.2
%
%
% History of MLTeX for TeX 3.x:
%
% 90/04/02 Version ?? (for TeX 3.0)
% \charsublist, \charsublistmax
% ??/??/?? Version 1.0
% 92/02/03 Version 2 (for TeX 3.1--3.141)
% |effective_char| uses explicit font information
% 93/10/29 Version 2.01
% fix \*leaders problem
% 95/12/06 Version 2.2 (for TeX 3.14159)
