Allows you to specify the target output file for your compiled presentation
Validity
Allows you to specify the date on which the presentation expires if you select the
"Expires?" checkbox. The presentation will be usable up to and including the
expiry date, but not afterwards. You can also specify here an HTML page to show if the
presentation has expired. Press the "Browse" button to locate the page required,
which must be within your "Web".
Take care when creating a presentation that expires. There are issues to think about.
You may need to control its distribution. People won't be very happy if they download a
large file only to find it is out-of-date.
