It is there, but it's pretty obscure.  A hint is that 'if' wants to execute 
something, and in the old days /bin/test and /bin/[ used to be links to the same 
executable.  These days the executables are in /usr/bin and not linked (don't 
know the reason for either...) but they are also shell builtins.
