For most applications, simply creating help files and adding ATTR_GEN_HELP_CONTEXT to certain generic objects will be sufficient. Other applications, though, such as those that use First Aid help, will require the addition of a HelpControl object (Normal help uses a system-provided and UI-run help controller).

The HelpControl object interacts with the GenClass and MetaClass aspects of generic objects to create help triggers, put up help screens, and determine which help file is used and what help context is displayed. For normal help, you don't need a HelpControl object; the system provides one. You do, however, have to know how to declare help contexts and work with help files.
