Suppose you are providing Help for a product with several optional modules, and you want to supply each customer with information only about the modules licensed by that customer. Or, suppose a user decides not to install a module, or adds a new module later. Or, suppose you have created reusable Help modules that can be incorporated into any of a number of main Help systems, such as "Help on Help".
Any Help system that Mif2Go generates can be made to access more than one module, yet appear to the user as a single unit. The user accesses a single Help file, and sees integrated contents, index, and related-topic links, containing information only for the relevant modules. Additional modules are loaded dynamically, when a user clicks a Contents, Index, Related Topics, or Search entry that references a separate module.
