  * Implementation of the RA-Interface for an external, (non-SSA) register allocator.
  *
  * The external register allocator is a program taking 2 arguments:
- *   1) An input file in which the cfg is defined
- *   2) An output file containing the essential actions performed during allocation
+ *   1) An input file in which the interference graph is defined
+ *   2) An output file containing the instructions to perform
