Version 1.1 Breaking Changes - mzh99/MHCmdLine GitHub Wiki

Starting in version 1.1, the ProcessCmdLine() function now returns a boolean for success instead of raising an exception.

False = a command-line argument failed the requirements. In this case, you can get the missing flags by calling var errmsg = "Missing required command line switches: " + string.Join(", ", cmd.GetMissingSwitchesRequired().ToArray());

True = the required command-line arguments were fulfilled.
