% This is the file plainenc.tex of the T2 package.
%
% This file defines some commands for Plain TeX, so that it is able to
% read (and interpret accordingly) some LaTeX files (unchanged), such as
% inputenc.sty, font encoding definition files (lcyenc.def, t2aenc.def,
% t1enc.def, etc.), and various input encoding definition files
% (koi8-r.def, latin1.def, etc.).
%
% These definitions are the `minimal' possible. Probably, some
% extensions will be needed.
