+%   URLWRITE Save the contents of a URL to a file.
+%   URLWRITE(URL,FILENAME) saves the contents of a URL to a file.  FILENAME
+%   can specify the complete path to a file.  If it is just the name, it will
+%   be created in the current directory.
+%
+%   F = URLWRITE(...) returns the path to the file.
+%
+%   F = URLWRITE(...,METHOD,PARAMS) passes information to the server as
+%   part of the request.  The 'method' can be 'get', or 'post' and PARAMS is a
+%   cell array of param/value pairs.
+%
+%   [F,STATUS] = URLWRITE(...) catches any errors and returns the error code. 
+%
+%   Examples:
+%   urlwrite('http://www.mathworks.com/',[tempname '.html'])
+%   urlwrite('ftp://ftp.mathworks.com/README','readme.txt')
+%   urlwrite(['file:///' fullfile(prefdir,'history.m')],'myhistory.m')
+% 
+%   From behind a firewall, use the Preferences to set your proxy server.
