Creating Your Own Service
Services
advertisements, such as the one
we listed earlier for the Stickies application, are stored in the
application’s
Info.plist
file, an XML-encoded file stored inside
the .app wrapper. When Mac OS X registers a new
application, it opens up the Info.plist file and
looks for the application’s application icon, its
document icons, and its Services advertisement (if it exists). This
information is cached to improve performance.
Table 20-4 lists all of the fields allowed in the Services advertisement.
