% \section{Font encodings}
%
%    This section of the kernel contains commands for declaring 
%    encoding-specific 
%    commands, such as accents.  It also contains the code for the
%    |T1enc.def| and |OT1enc.def| files, which define the 
%    |T1| and |OT1| encodings, and the |fontenc| package for selecting 
%    encodings. 
%
%    The |fontenc| package has options for encodings, of which the last 
%    option is the default encoding.  For example, to use the |OT2|, 
%    |OT3| and |T1| encodings, with |T1| as the default, you say:
%\begin{verbatim}
%    \usepackage[OT2,OT3,T1]{fontenc}
%\end{verbatim}
%    The syntax for declaring encoding-specific commands is:
%    \begin{quote}
%      |\DeclareTextCommand{|^^A
%         \meta{command}|}{|^^A
%         \meta{encoding}|}|\\\hspace*{\fill}|[|^^A
%         \meta{number}|][|^^A
%         \meta{default}|]{|^^A
%         \meta{commands}|}|
%    \end{quote}
%    This command is like |\newcommand|, except that it defines a
%    command which is specific to one encoding.  The resulting command
%    is always robust, even if its definition is fragile.  For example,
%    the definition of |\aa| in the |OT1| encoding is:
%\begin{verbatim}
%    \DeclareTextCommand{\aa}{OT1}{{\accent23a}}
%\end{verbatim}
%    |\DeclareTextCommands| takes the same optional arguments as
%    |\newcommand|.
%    \begin{quote}
%      |\DeclareTextSymbol{|^^A
%         \meta{command}|}{|^^A
%         \meta{encoding}|}{|^^A
%         \meta{slot}|}|
%    \end{quote}
%    This command defines a text symbol, with a particular slot in that
%    encoding.  The commands:
%\begin{verbatim}
%    \DeclareTextSymbol{\ss}{OT1}{25}
%    \DeclareTextCommand{\ss}{OT1}{{\char25}}
%\end{verbatim}
%    have the same effect, but the |\DeclareTextSymbol| is faster.
%    \begin{quote}
%      |\DeclareTextAccent{|^^A
%         \meta{command}|}{|^^A
%         \meta{encoding}|}{|^^A
%         \meta{slot}|}|
%    \end{quote}
%    This command declares a text accent.  The commands:
%\begin{verbatim}
%    \DeclareTextAccent{\"}{OT1}{127}
%    \DeclareTextCommand{\"}{OT1}[1]{{\accent127#1}}
%\end{verbatim}
%    have the same effect.
%    \begin{quote}
%      |\DeclareTextComposite{|^^A
%         \meta{command}|}{|^^A
%         \meta{encoding}|}{|^^A
%         \meta{slot}|}|
%    \end{quote}
%    This command declares a composite letter, for example in the |T1|
%    encoding |\'{a}| is slot 225, which is declared by:
%\begin{verbatim}
%    \DeclareTextComposite{\'}{T1}{a}{225}
%\end{verbatim}
%    The \emph{command} should have been declared with
%    |\DeclareTextAccent|, or as a one-argument |\DeclareTextCommand|.

%      |package|  & generates |fontenc.sty| for selecting encodings, \\

%
% This section contains definitions for commands such as accents which 
% depend on the current encoding.  These commands will usually be kept
% in |.def| files, for example |OT1enc.def| contains the definitions for
% the |OT1| encoding.
%    \begin{macrocode}
%<*2ekernel>
\message{font encodings,}
%    \end{macrocode}
%
% \begin{macro}{\DeclareTextCommand}
% \begin{macro}{\@changed@cmd}
% \begin{macro}{\@changed@x}
%    This is quite a complicated macro! If the current encoding is |OT1|
%    and you say:
%\begin{verbatim}
%    \DeclareTextCommand{\foo}{T1}...
%\end{verbatim}
%    then |\DeclareRobustCommand| is used to define |\foo| as
%    |\protect\foo<space>|, and |\foo<space>| as |\OT1-cmd \OT1\foo|
%    (where |\OT1\foo| is \emph{one} control sequence, not two!)
%    We then call |\newcommand| to define |\T1\foo|.
%    \begin{macrocode}
\def\DeclareTextCommand#1#2{%
   \expandafter\DeclareRobustCommand\expandafter#1%
      \expandafter{%

         \csname#2\string#1\endcsname
      }%
   \let\@ifdefinable\@rc@ifdefinable
   \expandafter\newcommand\csname#2\string#1\endcsname
}
\@onlypreamble\DeclareTextCommand
%    \end{macrocode}
%    The sneaky bit in all this is what |\OT1-cmd| does.  If the current
%    encoding is |OT1|, then |\OT1-cmd| is set to |\relax|, and so the
%    command |\OT1\foo| is executed.  But if the current encoding is,
%    say, |T1|, then |\OT1-cmd| is set to |\@changed@cmd|, which parses
%    the command name |\OT1\foo|, defines |\foo<space>| to be |\T1\foo|,
%    makes sure that |\T1\foo| is defined, and calls |\T1\foo|.

}
%    \end{macrocode}
% \end{macro}
%
% \begin{macro}{\DeclareTextSymbol}
%    |\DeclareTextSymbol{\foo}{OT1}{123}| uses a similar trick to\\
%    |\DeclareTextCommand|, but |\chardef|'s |\OT1\foo| to be slot 123.
%    \begin{macrocode}
\def\DeclareTextSymbol#1#2#3{%

% \begin{macro}{\DeclareTextComposite}
% \begin{macro}{\@text@composite}
% \begin{macro}{\@strip@args}
%    Another amusing game to play with |\expandafter|, |\csname|, and
%    |\string|.
%
%    When you say |\DeclareTextComposite{\foo}{T1}{a}{123}|,
%    we first check to make sure that |\T1\foo| is a one-argument macro,
%    by making sure that its |\meaning| begins |macro:#1-|, and call an
%    error if it isn't.  Assuming all's well, we look to see if the
%    expansion of |\T1\foo| begins with |\@text@composite|, and if it
%    doesn't, we redefine |\T1\foo| to be
%    |#1->\@text@composite\T1\foo{#1}{...}| where |...| is the previous
%    definition of |\T1\foo|.  Finally, we define |\\T1\foo-a|
%    to gobble two arguments and expand to character 123.
