-// able to use template specialisation to special-case their handling.
-//
-// IMPORTANT: This is primarily intended for use when sending file descriptors
-// over IPC. Even if |auto_close| is true, base::FileDescriptor does NOT close()
-// |fd| when going out of scope. Instead, a consumer of a base::FileDescriptor
-// must invoke close() on |fd| if |auto_close| is true.
-//
-// In the case of IPC, the the IPC subsystem knows to close() |fd| after sending
-// a message that contains a base::FileDescriptor if auto_close == true. On the
-// other end, the receiver must make sure to close() |fd| after it has finished
-// processing the IPC message. See the IPC::ParamTraits<> specialization in
-// ipc/ipc_message_utils.h for all the details.
