function makeinstall(varargin)
% MAKEINSTALL   creates a toolbox installation file.
%   Use MAKEINSTALL to create a INSTALL.M file, which
%   will include a simple installation script and all the
%   Matlab files which are needed for the toolbox. If the
%   CONTENTS.M file is missing, it will be automatically 
%   created. Furthermore the command TBCLEAN will be added to 
%   the toolbox folder, which enables to remove the toolbox 
%   folder and the startup entries.
%
%   Call MAKEINSTALL in the toolbox folder or specify this
%   folder with MAKEINSTALL TB-FOLDER.
%
%   In order to initialize some needed variables, call this
%   programme the first time and then modify the entries in 
%   the automatically created resource file MAKEINSTALL.RC.
%   You may change the entries in MAKEINSTALL.RC for your
%   convenience. 
%
%   Please note, that further files will be automatically 
%   generated in the toolbox folder if they do not exist yet: 
%   CONTENTS.M, INFO.XML and TBCLEAN.M.
%
%   The contents of CONTENTS.M will be generated from the help
%   lines in the M-files. If there are no help lines or if 
%   this help text is not correctly placed, a warning message 
%   will occur. Please ensure that the help text corresponds 
%   with the predefined structure of M-files:
%
%       function p = angle(h)
%       % ANGLE Polar angle.
%       %   ANGLE(H) returns the phase angles, in radians, of
%       %   a matrix with complex elements. Use ABS for the 
%       %   magnitudes.
%       p = atan2(imag(h),real(h));
%
%   where there is a first help line (H1) below the function 
%   line and a following help text. The H1 line is used also 
%   by other functions like LOOKFOR. If you like to generate 
%   CONTENTS.M automatically with MAKEINSTALL although 
%   CONTENTS.M already exists, you have to remove the old 
%   CONTENTS.M file. Thus, manual modifications will be kept.
%
%   The contents of INFO.XML can be modified with some 
%   variables in the resource file MAKEINSTALL.RC. However, 
%   you have to remove the old INFO.XML file, if you like to 
%   modify it the next time with MAKEINSTALL. Thus, manual 
%   modifications will be preserved.
