40// A SecCode that represents "generic" code.
41// Generic code is, well, generic. It doesn't have any real resources that define it,
42// and so it's defined, de facto, by its host. The Code Signing subsystem has no special
43// knowledge as to its nature, and so it just asks the host about everything. The asking
44// is done via the cshosting Mach RPC protocol, which can be implemented by hosts in whichever
45// way they find reasonable. This code doesn't care, as long as someone is answering.
46//
47// It is all right to subclass GenericCode to inherit access to the cshosting protocol.
