%%% Use this file to make a format based on the preamble of any LaTeX
%%% file.
%%%
%%% The format is made from the very beginning of the file up to either:
%%%   i) the command : \endofdump
%%%                    placed in the preamble
%%%  ii) the command : \csname endofdump\endcsname
%%%                    placed in the preamble
%%% iii) \begin{document}
%%%                    if \endofdump nor \csname endofdump\endcsname
%%%                    haven't been found in the preamble.
%%%
%%% A format helps to speed up compilations, packages which have been
%%% dumped in the format are loaded at very high speed.
%%% --------------------------------------------------------------------
%%% There are no restrictions on the distribution or modification of
%%% this file, except that other people should not attempt to alter
%%% the master copy on the ctan archives.
%%%
%%% Making the format --------------------------------------------------
%%% ^^^^^^^^^^^^^^^^^                                       USING MikTeX
%%% *  With preloaded pdflatex format (pdf output) :
%%%    etex -initialize [opts] "&pdflatex" mylatexformat.ltx """abc.tex"""
%%%    => compile your document using :
%%%            pdflatex
%%%         or texify --tex-option=-output-format=pdf
%%%
%%% *  With preloaded latex format (dvi output) :
%%%    etex -initialize [opts] "&latex" mylatexformat.ltx """abc.tex"""
%%%    => compile your document using
%%%            latex
%%%         or texify --tex-option=-output-format=dvi
%%%
%%% * With preloaded format xelatex (pdf output) :
%%%    xetex -initialize [opts] "&xelatex" mylatexformat.ltx """abc.tex"""
%%%    => compile your document using xelatex
%%%
%%% NOTA BENE:    Please, notice the 3 quotes !
%%% ^^^^^^^^^^
%%%
%%% In fact, 3 quotes are necessary only if you "file name.tex" contains a space !
%%%
%%% -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
%%% Exemple of a command line for making format using pdfTeX :
%%%
%%%   etex -initialize -interaction=nonstopmode
%%%                    -save-size=20000 -stack-size=20000
%%%                    -jobname="Mon Beau Format Perso"
%%%                    "&pdflatex" mylatexformat.ltx "Mon Fichier TeX.tex"
%%%
%%%   "Mon Beau Format Perso.fmt" (en Fran^^e7ais dans le texte) will be created
%%%   (or overwritten) in the current working directory.
%%%
%%% Using the format ---------------------------------------------------
%%% ^^^^^^^^^^^^^^^^^                                       USING MikTeX
%%% Add the format to the very first line of your LaTeX file :
%%% --> first line :       %&"format file name"
%%% without the .fmt extension.
%%% [You may use the option :    -dont-parse-first-line option
%%%  to avoid loading the format]
%%% --------------------------------------------------------------------
%% ____________________________________________________________________
%% The following informations come from mylatex.ltx from David Carlisle:
%% Given a LaTeX file `abc.tex', use initex as follows:
%%
%% initex &latex  mylatexformat.ltx abc      (Generic TeX)
%% initex \&latex mylatexformat.ltx abc      (unix and other TeX's)
%% tex /i &latex  mylatexformat.ltx abc      (emtex)
%%
%% If you are on a Mac or using some shell that makes it inconvenient
%% to use a command line such as the above examples then you may
%% make a file `mylatex.tex' with the single line
%% \input mylatex.ltx abc
%% and then pass the file mylatex.tex to your (ini)tex shell to produce
%% the format, ie something equivalent to initex &latex mylatex.tex.
%%
%% If you are using OzTeX, see the separate instructions below.
%%
%% This should make a format file mylatex.fmt which you can then use
%% as follows
%%
%% Using the new format
%% ^^^^^^^^^^^^^^^^^^^^
%%
%% tex  &mylatex abc          (generic TeX)
%% virtex \&mylatex abc       (Unix TeX)
%%
%% This will process your document, abc.tex, just as LaTeX does, but
%% quicker as the contents of the preamble will be stored in the
%% format file and will not need to be run each time.
%%
%% If (vir)tex fails to find your mylatex.fmt then it is not searching
%% in the current directory, either modify your TEXFORMATS path (or
%% equivalent) to search `.' or (on unix/dos) use   ./  as in:
%% virtex \&./mylatex abc
%%
%% Making and using the format with OzTeX
%% ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
%%
%% Given a LaTeX file `abc.tex', do this: select `TeX...' from OzTeX's
%% TeX menu, and go to the folder containing the file `abc.tex' as if you
%% were selecting the file `abc.tex'. Then hit the Cancel button - this
%% procedure sets OzTeX's working folder to the one containing abc.tex.
%% Next, select iniTeX from the TeX menu, and type:
%%
%% &latex mylatex.ltx abc
%%
%% This should make a format file mylatex.fmt which you can save in the
%% same folder as the file you're working on.
%%
%% To use the new format, put this at the very start of the very first
%% line of your document:
%%
%% %&mylatex
%%
%% Further Notes
%%
%% The file abc.tex must contain a line *just* with
%% \begin{document}
%% Everything up to (but not including) the \begin{document} will
%% be saved in the format and not executed in subsequent runs.
%%
%% If you are modifying the document (or working on a similar document)
%% you may wish to add new commands to your document preamble.
%% The `mylatex' format normally skips the whole preamble (believing
%% it to be pre-loaded) and so such new commands do not take effect.
%% You could re-make the format, preloading the new preamble, but that
%% might be inconvenient to do every time, and so an alternative scheme
%% has been introduced.
%% If the preamble contains a comment   mylatex  (ie a line just
%% containing a % white space and the word mylatex) then the mylatex
%% format will start reading the preable at that point so any new
%% commands can be placed after such a comment and they will be
%% executed.

%%\RequirePackage{etex}% RequirePackage may be used before the class
%%
%% In principle \openout stream= filename need not be space terminated,
%% and need not be immediate, but this covers \makeindex \makeglossary
%% and index package's \newindex which are all the cases of \openout
%% that occur before \begin{document} that I could see.
%% Thanks to Ross Moore for pointing out \AtBeginDocument is too late
%% eg changebar package *closes* the stream in \AtBeginDocument, so need
%% to make sure it is opened before that. Make a special purpose hook.
\makeatletter
%% \begin is overloaded in order to stop \dump at begin document
%% if the macro \endofdump is not given somewhere in the preamble.
%% Rem: it is NOT POSSIBLE to redefine \document, for the macro
%%      \document is changed or patched by some classes or packages
%%      (auxhook, etoolbox etc.)
