function cs_install (do_pause)
%CS_INSTALL: compile and install CSparse for use in MATLAB.
%   Your current working directory must be CSparse/MATLAB in order to use this
%   function.
%   
%   The directories
%
%       CSparse/MATLAB/CSparse
%       CSparse/MATLAB/Demo
%       CSparse/MATLAB/UFget
%
%   are added to your MATLAB path (see the "pathtool" command to add these to
%   your path permanently, for future MATLAB sessions).
%
%   Next, the MATLAB CSparse demo program, CSparse/MATLAB/cs_demo is executed.
%   To run the demo with pauses so you can see the results, use cs_install(1).
%   To run the full MATLAB test programs for CSparse, run testall in the
%   Test directory.
%
%   Example:
%       cs_install          % install and run demo with no pauses
%       cs_install(1)       % install and run demo with pauses
%
%   See also: cs_demo
