how to use --gauge in dialog
 

I'm writing an installation wizard using shell,and I'm trying to make it grahical using the dialog utility.The biggest problem is how to get the progress bar with --gauge.
The installation files is a bunch of .deb files and a Package.gz file,can use dpkg -i *.deb to be installed,the output is a bunch of strings with almost no numbers.

You can find a working example here.
