   ## Various ways of denoting ports and CPUs
   
   When discussing ports and CPUs, there are two concepts each of which have three ways of being named.  Strictly, the word port refers to the value shown by "uname -m", and typically corresponds to a directory under src/sys.  build.sh supports aliases, which are passed as if they were a port, but expand to a port and a cpu (MACHINE and MACHINE_ARCH); an example is evbearmv7hf-el which expands to the evbarm port and earmv7hf cpu.

   """]]
   
   Additonally, there are things referred to as ports which are notably different but are not actually "uname -m" values.  One is xen, which is a system architecture variant of i386/amd64, and aarch64, which is CPU type variant of evbarm.
