* 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
