% This style file eliminates the need for \protect'ion in:
%
%   1 - Argument of \thanks
%   2 - Argument (or optional argument) of \caption
%   3 - Optional argument of \bibitem
%   4 - Arguments of \addcontentsline and \addtocontents
%   5 - Sectioning commands (\chapter \section etc)
%       EXCEPT when the argument of a sectioning command appears in
%       a page heading (as for example is the case with \chapter and \section
%       commands in the book style).
%
%   The remaining problem of fragile commands within the headings
%   will be addressed later.
%
% The elimination of \protect within \caption and sectioning commands
% is made possible by suppressing the expansion of the arguments
% of these commands and by writing them into the .aux
% file as literal strings. This means that values of dynamic quantities
% cannot be included in these commands any more. If you need to reference
% a page, use \pageref instead of \the\page or something similar in the
% argument of \caption and/or sectioning commands.
% Thanks to David Carlisle for pointing this out.
%
% The following is a remedy for such rare cases:
% ===================================================================
% Let's assume you have a List of Figures, and that you MUST expand
% something at the point where \caption is issued, so that its value
% appears in the List of Figures entry. In the old scheme, you would say:
%
% \caption{First part of Caption \value{\MyCounter} Second part of Caption}
%
% and the value of the \MyCounter would appear in the List of Figures.
% But with this style file, you need to use a somewhat more complicated
% construct similar to the following:
%
% \def\CaptionI{First part of Caption}
% \def\CaptionII{Second part of Caption}
% \edef\temp{\noexpand\caption{\CaptionI \value{\MyCounter} \CaptionII}}
% \temp
%
% Here, we need the current value of a user-defined counter \MyCounter
% to be written into the .aux file which is read in the second run
% of latex to produce the List of Figures. Since its value presumably
% changes throughout the document, we want its value at the point that
% the \caption command is issued, rather than its value at the point
% that the List of Figures is typeset, to appear in the List of Figures.
% If you don't have a list of figures, then of course you needn't
% worry about any of this. The same considerations apply also for
% the arguments of sectioning commands that appear in the Table of Contents.
%
% The rationale for using this style file, of course, is that such
% cases are extremely rare! For one thing, most books/articles
% rarely contain a List of Figures and/or a List of Tables, and even
% when you do use one, the chances of needing an immediate expansion
% in a \caption command are small.
% ===================================================================
