CLI parser could report the bad parameters and flag them for the user

A mis-typed parameter can cause the parser to spit out the usage data e.g.:

-model-type

instead of the proper:

-type

Will cause the CLI to only spit out the usage for the command and not tell the user what is likely to be wrong... in this case a mis-typed parameter caused the problem.
Maybe only outputting usage data when no parameters, in most cases, and other times outputting the problem or place of the error.
