% It is desirable to reduce these three steps to the only interesting one, the middle one. This would mean that each new, subordinated file (henceforth, `subfile') should be \emph{both} part of a project and a self-sufficient \LaTeX\ document, depending on whether it is \LaTeX ed or |\included|/|\input|. This is what the set of class and package under the name |subfiles| is intended for.
%
-% The main idea behind it is the redefinition of |\documentclass| and the `environment' |document|; while these two features of \LaTeX\ are important to keep unchanged, |subfiles| changes them, as far as I know, harmlessly, and I have took care of undoing the changes when finished. This is the first version of |subfiles|, and although I have tried it a few times, it is still susceptible of conflicting with other packages and/or classes.

%
% \subsection{Results}
% This done, \LaTeX ing either the main or the subordinate file produces the following results:
% \begin{itemize}
% \item If the subfile is typeset by itself, it takes as preamble the one of the main file (including its |\documentclass|). The rest is typeset normally.
-% \item If the subordinated file was |\subfile|'d, it ignores everything before and including |\begin{document}|, and the ignores |\end{document}| too. (The body of the file, nothing else, is effectively |\input|.)
+% \item If the subordinated file was |\subfile|'d, it ignores everything before and including |\begin{document}|, and then ignores |\end{document}| too. (The body of the file, nothing else, is effectively |\input|.)
% \end{itemize}
%
% The |\subfile| command is more like |\input| than |\include| in the sense that it does not start a new page. It allows nesting, but there is no exclusion mechanism analogous to |\includeonly|.
%
% \subsection{Further details and warnings}
%
-% In all truth, a subfile typeset by itself does not exactly take the preamble of the main file, but \emph{anything outside} \verb|\begin{document}| and \verb|\end{document}|. This has two consequences: $a)$~the user can make some commands to be read only when the subfiles are typeset by themselves---which in any case are processed as part of the preamble; but also $b)$~the user has to be careful even \emph{after} |\end{document}| (in the main file), for any syntax error there will ruin the \LaTeX ing of the subfile(s).
+% To be precise, a subfile typeset by itself does not exactly take the preamble of the main file, but \emph{everything outside} \verb|\begin{document}| and \verb|\end{document}|.

%
-% The preamble of the main file can |\input| (not |\include| nor |\subfile|) other files (v.g\@. files with definitions and shorthand-commands), and the subfiles will too. But it has to be kept in mind that each subfile is |\input| within a group, so definitions made within them might not work outside. A good practice when using |subfiles| (and also when not using it) is to make any definitions in the preamble of the main file, avoiding confusion and allowing to find them easily.

% In principle, nesting files with |\subfile| should work and has worked in my tries, as far as every subfile loads the main file as its option to the |subfiles| class. However, who knows, the behavior can be unpredictable in weird situations. In any case, |subfiles| does \emph{not} disable |\include| nor |\input|, which remain available for free use.
%
-% |subfiles| class and package require the |verbatim| package (whose |comment| environment is used to ignore the different parts of different files); this should not be a problem since it makes part of the standard distribution of \LaTeX $2_\varepsilon$.

Therefore we save the contents of the two commands as |\old@document@subfiles| and |\old@enddocument@subfiles|, respectively.
