-====
-
-This repo contains the protocol definition for the host to BMC mailbox
-communication specification which can be found in
-Documentation/mbox_procotol.md.
-
-There is also a reference implementation of a BMC mailbox daemon, the details
-of which can be found in Documentation/mboxd.md.
-
-Finally there is also an implementation of a mailbox daemon control program, the
-details of which can be found in Documentation/mboxctl.md.
+For historical reasons, source and generated binaries may refer to 'mbox' or
+'the mailbox interface' in contexts that aren't completely sensible. It's
+unfortunate, but it's our current reality.

 The build system is a standard autotools setup. `bootstrap.sh` runs all the

-This codebase is a mix of C (due to its heritage) and C++. This is an ugly
