The best way of doing this is to use the PayPal IPN (Instant Payment
Notification) Tool - see
http://www.paypal.com/cgi-bin/webscr?cmd=p/xcl/rec/ipn-intro-outside.
This posts details of completed transactions to a specified URL, so
that you can then use a bit of programming, such as Perl to process
the data provided and create a code for the user to enter to download
the program required.
There is a Perl module to handle the IPN -
