% \section{Introduction}
%
% This file is used to generate the files \texttt{fonttext.ltx} (text
% font declarations) and \texttt{fontmath.ltx} (math font
% declarations), which are used during the format generation.  It
% contains the declaration of the standard text encodings used at the
% site as well as a minimal subset of font shape groups that NFSS will
% look at to ensure that the specified encodings are valid.
%
% The math part contains the setup for math encodings as well as the
% default math symbol declarations that belong to the encoding.
%
% It is possible to change this setup (by using other fonts, or
% defaults) without losing the ability to
% process documents written at other sites. Portability in this sense
% means that a document will compile without errors. It does not mean,
% however, that identical output will be produced. For this it is
% necessary that the distributed setup is used at both installations.
%
% \section{Customization}
%
% You are not allowed to change this source file!  If you want to
% change the default encodings and/or the font shape groups preloaded
% you should should create a copy of \texttt{fonttext.ltx}
% under the name \texttt{fonttext.cfg} and change this copy. If
% \LaTeXe{} finds a file of this name it will use it, otherwise it
% uses the standard file which is \texttt{fontdef.ltx}.
%
% If you don't plan to use Computer Modern much or at all, it might
% (!)  be a good idea to make your own \texttt{fonttext.cfg}. Look at
% the comments below (docstrip module `text') to see what should
% should go into such a file.
%
% To change the math font setup use a copy of \texttt{fontmath.ltx}
% under the name \texttt{fontmath.cfg} and change this copy. However,
% dealing with this interface is even more a job for an expert than
% changing the text font setup --- in short, we don't encourage either.
%
% \begin{quote}
%   \textbf{Warning:} please note that we don't support customised
%   \LaTeX{} versions. Thus, before sending in a bug report please try
%   your test file with a \LaTeX{} format which is not customised and
%   send in the log from that version (unless the problem goes away).
% \end{quote}
%
% Please note: the following standard encodings  have to
% be defined in all local variants of \texttt{font....cfg} to guarantee
% that all \LaTeX{} installations behave in the same way.
% \begin{center}
% \begin{tabular}{ll}
%   |T1|      &    Cork \TeX{} text encoding \\
%   |OT1|      &   old \TeX{} text encoding \\
%   |U|        &   unknown encoding \\
%   |OML|      &   old \TeX{} math letters encoding \\
%   |OMS|      &   old \TeX{} math symbols encoding \\
%   |OMX|      &   old \TeX{} math extension symbols encoding\\
%   |TU|      &   Unicode
% \end{tabular}
% \end{center}
% Notice that some of these encodings are `old' in the sense that we
% hope that they will be superseded soon by encoding standards defined
% by the \TeX{} user community. Therefore this set of default encodings
% may change in the future.
%
% The first candidate is |OT1| which will soon be replaced by |T1|, the
% official \TeX{} text encoding.
%
% \begin{quote}\textbf{Warning:}
% If you add additional encodings to this file there is no guarantee
% any longer that files processable at your installation will also be
% processable at other installations. Thus, if you make use of
% such an encoding in your document, e.g.~if you intend to typeset in
% Cyrillic (|OT2| encoding), you need to specify this encoding in the
% preamble of your document prior to sending it to another
% installation. Once the encoding is specified in that place in your
% document, the document is processable at all \LaTeX{} installations
% (provided they have suitable fonts installed).
%
% For this reason we suggest that you define a short package file that
% sets up an additional encoding used at your site (rather than
% putting the encoding into this file) since this package can easily
% be shipped with your document.

% \section{The \texttt{docstrip} modules}
%
% The following modules are used to direct \texttt{docstrip} in
% generating external files:
% \begin{center}
% \begin{tabular}{ll}
%   driver & produce a documentation driver file \\
%   text   & produce the file \texttt{fonttext.ltx}\\
%   math   & produce the file \texttt{fontmath.ltx}\\
%   cfgtext   & produce a dummy \texttt{fonttext.cfg} file\\
%   cfgmath   & produce a dummy \texttt{fontmath.cfg} file\\
% \end{tabular}
% \end{center}
% A typical \texttt{docstrip} command file would then have entries like:
% \begin{verbatim}
%\generateFile{fonttext.ltx}{t}{\from{fontdef.dtx}{text}}
%\end{verbatim}
%
%
% \section{A driver for this document}
%
% The next bit of code contains the documentation driver file for
% \TeX{}, i.e.~the file that will produce the documentation you are
% currently reading. It will be extracted from this file by the
% \dst{} program.

%
%  \subsection{Encodings}
%
%    This file declares the standard encodings for text and math
%    fonts. All others should be declared in packages or in the
%    documents directly.
%
%    For every text encoding there are normally a number of encoding
%    specific commands, e.g.~accents, special characters, etc.  (The
%    definition for such a command might have to change when the
%    encoding is changed, because the character is in a different
%    position, or not available at all, or the accent is produced in a
%    different way.)  This is handled by a general mechanism which is
%    described in \texttt{ltoutenc.dtx}.
%
%    By convention, text  encoding specific declarations, including the
%    declaration |\DeclareFontEncoding|, are kept in separate file of
%    the form \meta{enc}\texttt{enc.def}, e.g.~\texttt{ot1enc.def}. This
%    allows other applications to make use of the declarations as
%    well.
%
%    Similar to the default encoding, the loading of the encoding
%    files for the two major text encodings shouldn't be changed.
%    In particular, the \texttt{inputenc} package depends on this.

%
%    We then set set the default text font encoding. This will
%    hopefully change some day to |T1|. This setting should \emph{not}
%    be changed to produce a portable format.

%    \end{macrocode}
%
%    If different encodings for text fonts are in use one could put
%    the common setup into |\DeclareFontEncodingDefaults|. There is
%    now a better mechanism so using this interface is discouraged!
%    \begin{macrocode}
\DeclareFontEncodingDefaults{}{}
%    \end{macrocode}
%
%    Then we define the default substitution for every encoding.
%    This release of \LaTeXe{} assumes that the ec fonts are
%    available. It is possible to change this to point to some other
%    font family (e.g., Times with the appropriate encoding if it is
%    available) without making documents non-portable. However, in
%    such a case documents will produce different page breaks at other
%    sites. The substitution defaults can all be changed without
%    losing portability as long as there are font shape definitions
%    for the selected substitutions.
%    \begin{macrocode}
\DeclareFontSubstitution{T1}{cmr}{m}{n}
\DeclareFontSubstitution{OT1}{cmr}{m}{n}
%    \end{macrocode}
%
%    For every encoding declaration, \LaTeXe{} will try to verify that
%    the given substitution information makes sense, i.e.~that it is
%    impossible to go into an endless loop if font substitution
%    happens. This is done at the moment the |\begin{document}| is
%    encountered. \LaTeXe{} will then check that for every encoding the
%    substitution defaults form a valid font shape group, which means
%    that it will check if there is a |\DeclareFontShape| declaration
%    for this combination. We will therefore load the corresponding
%    |.fd| files now. If we don't do this they would be loaded at
%    verification time (i.e.~at |\begin{document}| which would delay
%    processing unnecessarily.
%
%    \begin{quote}
%       \textbf{Warning:} Please note that this means that you have to
%       regenerate the format whenever you change any of these
%       \texttt{.fd} files since \LaTeXe{} will not read \texttt{.fd}
%       files if it already knows about the encoding/family
%       combination.
%    \end{quote}
%
% \changes{v2.2m}{1995/11/01}{add \cs{nfss@catcodes} for internal/1932}
% The |\nfss@catcodes| ensures that white space is ignored in any
% definitions made in the fd files.
%    \begin{macrocode}
\begingroup
\nfss@catcodes
\input  {t1cmr.fd}
\input  {ot1cmr.fd}
\endgroup
%    \end{macrocode}
%
%    We also load some other font definition files which are normally
%    needed in a document. This is only done for processing speed and
%    you can comment the next two lines out to save some memory. If
%    necessary these files are then loaded when your document is
%    processed. (Loading |.fd| files is a less drastic step compared
%    to preloading fonts because the number of fonts is limited 255 at
%    (nearly) every \TeX{} installation, while the amount of main memory
%    is not a limiting factor at most installations.)
%
%    \begin{macrocode}
\begingroup
\nfss@catcodes
\input {ot1cmss.fd}
\input {ot1cmtt.fd}
\endgroup
%    \end{macrocode}
%
%    Even with all the precautions it is still possible that NFSS will
%    run into problems, for example, when a |.fd| file contains
%    corrupted data. To guard against such cases NFSS has a very
%    low-level fallback font that is installed with the following line.
%    \begin{macrocode}
\DeclareErrorFont{OT1}{cmr}{m}{n}{10}
%    \end{macrocode}
%    This means, ``if everything else fails use Computer Modern Roman
%    normal shape at 10pt in the old text encoding''.
%    You can change the font used but the encoding should be the same
%    as the one specified with |\fontencoding| above.
%
%
% \subsection{Defaults}
%
%    To allow the use of |\rmfamily|, |\sffamily|, etc.\ in documents
%    even if non-standard families are used we provide nine macros
%    which hold the name of the corresponding families, series, and so
%    on. This makes it easy to use other font families (like Times
%    Roman, etc.). One simply has to redefine these defaults.
%
%    All these hooks have to be defined in this file but you can
%    change their meaning (except for |\encodingdefault|) without
%    making documents non-portable.
%
%
% \begin{macro}{\encodingdefault}
% \begin{macro}{\rmdefault}
% \begin{macro}{\sfdefault}
% \begin{macro}{\ttdefault}
%    The following three definitions set up the meaning for
%    |\rmfamily|, |\sffamily|, and |\ttfamily|.

%    Finally a declaration for |U| encoding which serves for all fonts
%    that do not fit standard encodings. For math this sets up
%    |\noaccents@| providing for AMS-\LaTeX{}. This macro is used
%    therein to handle accented characters if they are not supported
%    by the font. In other words, if fonts with |U| encoding are used
%    in math, all accents (like from |\breve|) are obtained from some
%    other font that has them.
%    \begin{macrocode}
\DeclareFontEncoding{U}{}{\noaccents@}
%    \end{macrocode}
%    The encodings for math are next:

%
%  \subsubsection{Symbolfont and Alphabet declarations}
%
%    We now define the basic symbol fonts used by \LaTeX{}.
%    These four symbol fonts must be defined by this file.
%
%    It is possible to make the symbol fonts point to other external
%    fonts without losing the ability to process  documents written
%    at other sites, as long as one defines the same symbol font names
%    with the same encodings, e.g.~|operators| with |OT1| etc.
%    If other encodings are used documents become non-portable.
%    Such a change should therefore be done in a package file.

%    Below are the seven math alphabets which are defined by NFSS.
%    Again they must be defined by this file.
%    However, as before you can change the fonts used without losing
%    portability, but you should be careful when changing the encoding
%    since that may make documents come out wrong.

\DeclareMathAlphabet      {\mathit}{OT1}{cmr}{m}{it}
\DeclareMathAlphabet      {\mathtt}{OT1}{cmtt}{m}{n}
%    \end{macrocode}
%    Given the currently available fonts we cannot bold-en |\mathbf|
%    and |\mathtt| but in principle one could use `ultra bold' or
%    something. The alphabets defined via |\DeclareSymbolFontAlphabet|
%    will change automatically in a new math version if the
%    corresponding symbol font changes.

% \changes{v2.2f}{1994/11/07}
%     {(DPC) Add \cs{DeclareMathSizes} declarations}
%
%    The declarations below declare the text, script and scriptscript
%    size to be used for each text font size.
%
%    All occurrences of sizes longer than a single character are replaced
%    with the macro name that holds them, saving a number of
%    tokens (but losing a bit of speed, so this may not stay this way).

% \subsection{The math symbol assignments}
%
%    We start by setting up math codes for most of the characters
%    typed in directly from the keyboard. Most of them are normally
%    already setup up in the same way by Ini\TeX{}. However, we repeat
%    them here to have a complete setup which can be exchanged with
%    another if desired.

%    There are three plain \TeX{} delimiters which are not fully
%    supported by NFSS, since they partly point into a bold cmr font.
%    Allocating a full symbol font, just to have three delimiters
%    seems a bit too much given the limited space available.  For this
%    reason only the extensible sizes are supported.  If this is not
%    desired one can use, without losing portability, define |\mathbf|
%    and |\mathtt| as font symbol alphabet (setting up
%    \texttt{cmr/bx/n} and \texttt{cmtt/m/n} as symbol fonts first)
%    and modify the delimiter declarations to point with their
%    small variant to those symbol fonts. (This is done in
%    \texttt{oldlfont.dtx} so look there for examples.)
