function vanity
% VANITY    Display your File Exchange downloads and rank statistics, 
%           add them to a history file (fex.mat in work directory, by
%           default), and play Handel's Hallelujah chorus if rank has 
%           improved. Modify  code by entering URL of own author page
%           and location of history file, if desired.
