Hot Potatoes (Windows only) includes a program called the Masher. The Masher is a tool for automatically compiling batches of Hot Potatoes exercises into units. Imagine that you have five Hot Potatoes exercises that form a single unit of materials. You want to build HTML files from all the exercises, with the same colours and appearance settings; you also want to link the exercises together using the navigation buttons, and create an index file for the unit. The Masher will do that for you.
From September 1, 2009, Hot Potatoes is available as freeware, and the Masher no longer requires a separate registration key. If you want to use the Masher, just download the latest version of Hot Potatoes from the Hot Potatoes home page at the University of Victoria. When you have installed the program and provided a user name, you will be free to use all of the Hot Potatoes programs, including the Masher.
