+% \section{Loading the package}
+%
+% Load this package using
+% \begin{quote}
+%   |\usepackage|\oarg{options}|{totalcount}|\quad,
+% \end{quote}
+% where \meta{options} is a list of names of \LaTeX\ counters, e.g.:
+% \begin{quote}
+%   |\usepackage[figure,table]{totalcount}|\quad.
+% \end{quote}
+% \pagebreak[3]
+% This way the commands |\total|\-|figures| and |\total|\-|tables| will be defined which
+% are typesetting the total number of figures resp.~tables, e.g.:
+% \begin{quote}
+%   |This document contains \totalfigures\ figures.|
+% \end{quote}
+% \pagebreak[3]
+% Furthermore the commands |\if|\-|total|\-|figures| and |\if|\-|total|\-|tables| are offered
+% for typesetting text only if the document contains figures resp.~tables at all, e.g.:
+% \begin{quote}
+%   |\iftotalfigures|\\
+%   |  \listoffigures|\\
+%   |\fi|
+% \end{quote}
+% \pagebreak[3]
+% This should work with other counters as well (for example |equation|,
+% or |lst|\-|listing| offered by the \package{listings} package~\cite{listings}),
+% but please note that using the |page| counter here is not supported.
+%
+% \pagebreak[3]
+% \section{\cs{DeclareTotalCounter}}
+% \begin{quote}
+%   |\DeclareTotalCounter|\marg{counter}
+% \end{quote}
+% actually defines the commands |\total|\meta{counter}|s| and |\if|\-|total|\meta{counter}|s|.
+%
+% \pagebreak[3]
+% So in fact
+% \begin{quote}
+%   |\usepackage[figure,table]{totalcount}|
+% \end{quote}
+% is identical to
+% \begin{quote}
+%   |\usepackage{totalcount}|\\
+%   |\DeclareTotalCounter{figure}|\\
+%   |\DeclareTotalCounter{table}|
+% \end{quote}
+%
+% \pagebreak[3]
+% \section{Spacing}
+% The space after all \LaTeX\ commands without (optional or mandatory) arguments
+% like |\total|\-|figures| will not be typeset,
+% so these commands needs to be finished with an additional backslash or an empty
+% pair of curly braces right before the space character,
+% or to be finished with a tilde (swung dash),
+% so \TeX\ will be prevented from omitting the following space character.
+%
+% \pagebreak[3]
+% This could be avoided by defining new commands with the help of
+% the \package{xspace} package~\cite{xspace}.
+% When using \thispackage\ with the package option |xspace| this will be actually done,
+% so after
+% \begin{quote}
+%   |\usepackage[figure,table,xspace]{totalcount}|
+% \end{quote}
+% code like
+% \begin{quote}
+%   |This document contains \totalfigures figures.|
+% \end{quote}
+% will give correct results without a missing space between the total number of figures
+% and the word ``figures''.
+%
+% \pagebreak[3]
+% \section{Thanks}
+% I would like to thank Herbert Vo\ss\ since the implementation of this package is
+% based on an idea from him which could be found at
+% \url{http://texnik.dante.de/cgi-bin/mainFAQ.cgi?file=counter/counter#number}.
