% LaTeX includes a command \@addtoreset that is used to declare that
% a counter should be reset every time a second counter is incremented.

% For example the book class has a line
% \@addtoreset{footnote}{chapter}
% So that the footnote counter is reset each chapter.

% If you wish to base a new class on book, but without this counter
% being reset, then standard LaTeX gives no simple mechanism to do
% this.

% This package defines |\@removefromreset| which just undoes the effect
% of \@addtoreset. So for example a class file may be defined by

% \LoadClass{book}
% \@removefromreset{footnote}{chapter}

% 2018: package obsoleted as the command is defined in the LaTeX format.
