Avoid panicking with invalid option args #288

Closed GreasySlug closed 1 year ago

GreasySlug commented 1 year ago

In Erg, it caused panic when there was an invalid argument. However, in other languages, instead of panicking, indicate that it is an invalid argument and have them refer to help. Added a message to that effect.

Good. One thing I would add is that in Python, the return code seems to be 2 when an invalid option is passed, Erg should do that as well.

Thanks!
