Yes, I agree. I don't know what it is called. CC was a placeholder.

libexec is for programs that a human doesn't normally run directly nor 
configure to be started up. For example, postfix has several 
non-interactive tools that say:

                foo: fatal: do not run this command by hand

They are usually tools launched by something else, like 
libexec/gnome-keyring-ask is launched by libgnomeui. Or 
libexec/hald-addon-storage is launched by the hald daemon when needed. 
Another example is a POP3 server that knows no networking and so is 
launched by inetd.

I added it on the assumption we'd have commands that we'd consider that 
no human would have run nor start.
