7. System Services

“Service with a smile!”

—Business slogan

System Services, hereinafter referred to as services, are applications that provide custom capabilities to other applications. They can be found in the Services submenu of the application menu, as shown in Figure 7.1. Services are usually background-only applications and do not have a user interface as a normal application would, although they might display a window for user input or feedback if needed. Examples of services include spell checkers, screen grabbers, and text manipulators such as the one we will look at in this chapter.
