% F_REGREADER: Register the Adobe Acrobat Reader with FDSP
%
% Usage: k =f_regreader
%
% Description:
%              The Problems menu option of f_dsp allows the 
%        user
%              to access PDF files which contain solutions to 
%              selected problems.  To activate this option you 
%              must have an Adobe Acrobat Reader installed, and 
%              you must register the reader file with FDSP using
%              the Problems/Register menu option.  If you do not 
%              have an Adobe Acrobat Reader installed, you can 
%              download a free copy of the Acrobat Reader using 
%              the Problems/Download menu option, or by directly 
%              accessing the Adobe web site:
%
%              http://www.adobe.com/products/acrobat/readermain.html
% Outputs: 
%          k = integer that is nonzero if a reader file was 
%              found and zero if it was not.
