geturl(theURL, theFilename)
function theResult = geturl(theURL, theFilename)

% geturl -- Get a URL.
%  geturl('theURL', 'theFilename') calls Netscape to get
%   'theURL', saving it to 'theFilename'.  If a wildcard
%   filename is provided, the "uiputfile" dialog is invoked.
%   If no path is given, the current directory is used.
%   If no filename is given, or if it is '', the file is
%   opened in an active Netscape window.  This routine
%   does not wait for the completion of the download.
%
%  Note to users: The path to Netscape must be hardwired
%   into the "geturl.mac" AppleScript, a text file that
%   can be modified with the Matlab editor.
