"Table 1  StartupParameters.plist key-value pairs

Key		Type	Value
Description	String	A short description of the startup item,
			used by administrative tools.

Provides	Array	The names of the services provided by this
			startup item.  Although a startup item can
			potentially provide multiple services, it is
			recommended that you limit your startup items
			to only one service each."

Fix "Provides" to be the name of the service, not a description of the
helpful operations that it provides.
