% Word counting
%
% TRB requires the total number of words, figures, and tables to be displayed
% on the title page. Since v2.1, we:
% - count the words in the body text and bibliography using the 'texcount'
%   utility that comes with most TeX distributions,
% - count the number of tables and figures, and
% - compute a total wordcount.
%
% The user can:
% - Use \setcounter{textwords}{1234} in the preamble to avoid use of texcount.
% - Override the word equivalents for figures and tables. The defaults are:
%   \setcounter{wordsperfigure}{250}
%   \setcounter{wordspertable}{250}

% catchfile: for \CatchFileDef
\RequirePackage{catchfile}

% totcount: for counters

% Number of words in body text and bibliography
\newcounter{textwords}

% Total words including word equivalents of tables and figures

  % Read the word count and set textwrods
  \CatchFileDef{\@textwords}{\jobname.count}{}
