%       and an article (ontesting.pdf) on the tests.
%
% Generation of testsample.tex is with

% which contains   
%    \generate{\file{testsample.tex}

%\section{Introduction}
%
% Here we discus the |testsample.tex| document 
% that is a test bed for the {\sf makeshape} package \cite{makeshape} 
% and its sample shape.
% The package is in |makeshape.sty| and the sample shape is defined in |sampleshape.tex|.
% The test bed can be usefully adapted to work with any PGF \cite{pgfMan} shape  
% developed with the {\sf makeshape} package. 
%
% There are 11 test PGF pictures in the |testsample.tex| document, 
% and we describe what each of these tests achieves, and what aspects are important for custom shapes.

% \section{Reuse}
% 
% The |testsample.tex| file can be adapted to test other shapes developed using
% the {\sf makeshape} package. Find the following section:
% 
% \begin{verbatim}
% %%-------------------------------------------------
% %% file and shape being tested
% \def\filename{sampleshape}   % file being tested
% \input{\filename}            % It is a .tex 
% %%\usepackage{\filename}     % It is a .sty
% \def\testshape{sample}       % shape being tested
% %%-------------------------------------------------
% \end{verbatim}
% Then change |sampleshape| to the new file name, and |sample| to the particular shape's name.
% Choose |\input| or |\usepackage| dependinmg on the file type.
%
% The report's ending `Package Test' section can be deleted, and additional shape specific tests added. 
% The file's {\sf makeshape} package oriented name 
% and its heading comment should probably be changed as well.
