In general, any utility created for BRP should also be able to be run in a standalone manner; that is, it should run outside of and separate from BRP as well. Typically this means getting parameters from a CFG file. This is already being done for all pre-processing type utilities right now. There are occasional situations where this is not practical. The utility needs to be able to determine whether it is being executed in a BRP context or not. If the stand-alone mode requires a CFG file, the absence of a CFG file parameter can serve as a trigger for BRP-mode execution. Where this will not work, the first parameter of the utility should be "BRP" to trigger BRP-mode execution.
