% to each line of the input between \cs\begin\M*{{\dg parse lines}}\, and\, \cs\end\M*{{\dg parse lines}}.
%
% There is also a macro: \cs\dofilebyline: its purpose is to expand a user-defined macro \cs\do with

% \begin{declcs}[\red]{dofilebyline}\M{file-name} \\
%  \cs[\red]{dofilebyline}\stform*\M{file-name}
% \end{declcs}
%
% Expands the macro \csbf{do} on each line of a given file.
%
% Each line is read using the \TeX{} primitive \csbf{read}. By default, \cs\endlinechar is suppressed ({\vb\cs\endlinechar=-1})
% in order not to add a space at the end of each line read. If you do not want this behaviour, use the \stform* star form.
%
% If the file does not exist, an error is displayed.
%
%
% Example:
% \begin{VerbLines}
%     \def\do#1{\ifx\par#1\else \addto@hook\mytoken{#1}\fi}%
%     \dofilebyline{file name.tex}
% \end{VerbLines}
%
% In this example: \cs\ifx\cs\par\#1\cs\else will evaluate to \texttt{false} if \#1 is empty.
% Therefore, empty lines and double empty lines (equivalent to \cs\par) are not captured into the token \cs\mytoken.
