+\message{MeX configuration,}
+
+% The following lines define which hyphenation patterns
+% are to be included in the current configuration of the MeX format.
+% We assume that fonts with different positions of Polish diacritical
+% characters can be used within the same document and each font layout
+% requires its own hyphenation patterns.
+% The standard positions of Polish diacritical characters in TeX's fonts
+% is the layout accepted at the 5th European TeX Conference in Cork (1990);
+% this layout is called here `PL'.
+%
+% The standard configuration of the MeX format includes the hyphenation
+% patterns for:
+%   - the English language (OK for all fonts),
+%   - the Polish language used with the fonts in the `PL' layout.
+% In such configuration switching to another font layout disables
+% hyphenation for the Polish language.
+%
+% However, the hyphenation patterns for other layouts of fonts including
+% Polish diacritical letters are prepared and if memory space in the
+% particular instalation of TeX permits the user is free to use INITEX
+% to generate a new MeX or LaMeX format containing these patterns.
+% Just `unpercent' some of the following lines.
+
+\hyph@nate{english}
+\hyph@nate{pl}
+%\hyph@nate{pone}
+%\hyph@nate{mazovia}
+%\hyph@nate{latintwo}

+% ``deafault'' means -- at the beginning
+% (unpercent only one possibility)

+% in PLAIN.TeX and LFONTS.TeX files the prefix:
+\def\@ldpref % exactly two characters
+    {cm}
+% is changed to:
+\def\n@wpref % an arbitrary number of characters
+    {pl}

+\def\l@tex % the name of the file containing the original latex file

+    {latex.tex}
+\def\P@lhyphen % name of the file containing Polish hyphenation patterns
