+\message{prefixing,}
+% prefixing and non-prefixing
+
+% In the following section nothing is dependent on particular
+% codes of Polish characters in a font.
+
+% The following Polish characters in the Mazovia encoding
+% are used in comments:
+%            �  �  �  �
+% (meaning: /a /c /e /Z)
+
+% there are two possible notations:
+%   1. with \prefixing turned on:                     /a /c /e ...
+%   2. with \prefixing turned off (\nonprefixing):    �  �  �  ...

+\@ct\/

+\@th\/

+    {\let\pr@fix F\@th\/}
+% we use \let\pr@fix T and \let\pr@fix F instead of \newif-s

+% \normalslash expands to  /  of category `other'

+% In the forthcoming definitions the following short macro expanding to

+        {\ifx/}
+\@th\/% / is "other" again
+% we will define a macro expanding to `\ifx/#1/\else...' where the first /
+% is active and the remaining ones are of the category `other'
+
+% The active / will be a synonim of the macro \P@lch,
+% where \P@lch is equivalent either to \pslash or to \l@slash
+% in Plain or in LaTeX, respectively;

+% definitions of codes in the font layout in the Polish fonts:
+% (the hexadecimal digits may be upper or lowercase)
+
+% Each of the following \d@finelayout commands
+% includes the definition of a \f@nt<layout> command,
+% where <layout> is a font layout name like `pl' `mazovia' etc.
+
+% The \f@nt<layout> command results in executing several times
+% a command of the form:      \@Pl <letter> <code>
+% and a command of the form:  \@qq <char><char> <code>
+%
+% There are two meanings of the \@Pl and \@qq commands:
+% the primary meanings and the secondary meanings.
+%
+% The primary meanings of the commands \@Pl and \@qq
+% change the `state' of MeX, in the following way:
+%
+% command of the form: \@Pl <letter> <code>
+% (take \@Pl a a1 as an example, i.e., <letter>=a <code>=a1)
+%   - define the character of the code a1 as a `letter'
+%   - define the control sequence /a as a macro expanding to the
+%     letter of the code a1
+%   - define the control sequence /aa as a macro expanding to the
+%     two-character uppercase hexadecimal code of the corresponding
+%     letter, in this case to A1
+%
+% command of the form: \@qq <char><char> <code>
+% (take \@qq ,, ff as an example, i.e., <char>=, <code>=ff)
+%   - define the control sequence /,, as a macro expanding to the
+%     two-character uppercase hexadecimal code of the corresponding
+%     quotation mark, in this case to FF
+
+% The secondary meanings of the commands \@Pl and \@qq are the following:
+
+% command of the form: \@Pl <letter> <code>
+% (take \@Pl a a1 as an example, i.e., <letter>=a <code>=a1)
+%   - define the character of the code a1 as an active character
+%   - define this active character as a macro expanding to the
+%     polish diacritical letter corresponding to a, in the current
+%     font layout)
+%
+% command of the form: \@qq <char><char> <code>
+%   - do nothing
+
+% the default meaning is primary
+% it is redefined for a moment by the macro \layout

+\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.
