-//	- PowerBook and iBook access methods are model- and OS version-specific
-//
-// So, the sequence of tests is:
-//	- Try model-specific access methods. Note that the test is for a match to the
-//		beginning of the model name, e.g. the record with model name "MacBook"
-//		matches computer models "MacBookPro1,2" and "MacBook1,1" (and ""
-//		matches any model).
-//	- If no model-specific record's access fails, then try each model-independent
-//		access method in order, stopping when one works.
