Description

It is a common expectation for users that using `--help` on a program will *NOT* start the program. Likewise, when a user makes a typo in the arguments passed to a program, the program should *NOT* start.

The arguments parsing in DRuntime doesn't do any of this. `--DRT-gcopts=foo` (notice the extra 's' after `gcopt`) will happily run the program, and so will `--DRT-gcopt=help`.
