% \section{Overview}
% The package method can be used to easily format method- and
% variabledeclarations with \LaTeX.
% It is based on work by J. Wahlmann and Robert Garmann.
% 
%\section{Usage}
% The package is used as usual:
%\begin{quote}
% |\usepackage[<language>]{method}|
%\end{quote}
% It defines two new environments: method and data. Method is used to
% typeset method-declarations, data for variable-declarations.
% At the moment the two options \textsf{english} and \textsf{german}
% are defined. With these options it is possible to select the language
% used to typeset the declarations. In the future some other languages
% will be added.
%
%\section{The environment method}
% \DescribeEnv{method}
% Within the environment
% method the following commands are defined:
%
%\begin{itemize}
%\item \DescribeMacro{\head}
%  \cs{head}\texttt{\{\emph{Header}\}:} The header of the method.
%\item \DescribeMacro{\para}
%  \cs{para}\texttt{\{\emph{Name}\}\{\emph{Description}\}:}
%  Name and description of a parameter.
%\item \DescribeMacro{\precond}
%  \cs{precond}\texttt{\{\emph{Precondition}\}:}
%  Description of a precondition of the method.
%\item \DescribeMacro{\descr}
%  \cs{descr}\texttt{\{\emph{Description}\}:}
%  Description of the method itself.
%\item \DescribeMacro{\postcond}
%  \cs{postcond}\texttt{\{\emph{postcondition}\}:}
%  Description of a postcondition of the method.
%\item \DescribeMacro{\error}
%  \cs{error}\texttt{\{\emph{Exception}\}:} Error and exceptions.
%\item \DescribeMacro{\return}
%  \cs{return}\texttt{\{\emph{Return value}\}:}
%  Description of the data returned by the method.
%\item \DescribeMacro{\see}
%  \cs{see}\texttt{\{\emph{where}\}:} Cross-References.
%\end{itemize}
%
%These commands have the following in common:
%\begin{itemize}
%\item All parameters are simple texts.
%\item The sequence of the commands inside the method-environment is
%  not relevant. The parts are typeset automatically.
%\item Up to 26 \cs{para}-commands are allowed inside a method
%  environment. When there are more, a warning will be issued und the
%  following parameters will be ignored.
%\item The header of the method and the parameters are typeset in a
%typewriter font.
%\item If the header is extremely long, it can be typeset in more
%lines with the following macros (an example is given further down):
%\begin{verbatim}
%       \headtabbed{<functionname>}     Name of the function
%       \headpara{<parametername>}      one or more parameter
%\end{verbatim}
%\end{itemize}
%
%\section{The environment data} \DescribeEnv{data}
% The environment data equals to the environment method. The macros 
% \cs{head}, \cs{descr} and \cs{see} can also be used inside a
% data-environment.
% Further macros inside a data-environment are:
%\begin{itemize}
%\item \DescribeMacro{\init}
%  \cs{init}\texttt{\{\emph{Info}\}:} Information about the generation
%  of the objekt.
%\item \DescribeMacro{\del}
%  \cs{del}\texttt{\{\emph{Info}\}:} Information about the release of
%  the object.
%\end{itemize}
%
%\section{Examples}
%In this section some examples for the usage of the environments
%method and data are shown.
%\begin{verbatim}     
%      \begin{method}
%       \head{int div(int a, int b, double \&c);}
%       \para{a}{dividend}
%       \para{b}{divisor}
%       \para{\&c}{result of the division}
%       \precond{no preconditions}
%       \descr{Divides \texttt{a} by \texttt{b} and gives the result
%       in \texttt{c}}
%       \postcond{no postconditions}
%       \error{no errors}
%       \return{\texttt{-1}, when  \texttt{b==0}, else \texttt{0}}

%\section{Package internals}
%
% At the start of a method-environment the actual textwidth is read
% and saved for the layout of the description.
%
% The commands for the parts, namely \cs{head}, \cs{para},
% \cs{precond}, ..., define
% internal commands with the names \cs{meth@head}, \cs{meth@pa},
% \cs{meth@pb}, ..., \cs{meth@pz},
% \cs{meth@precond}, ...  which are defined with the actual
% parameters.
%
% At the end of a method-environment all these internal saved data is
% typeset in a (hopefully) fashionable way.

% The counter \cs{meth@headparanum} stores how many 
% \cs{headpara}-commands are given within a method-environment:
