Surround an argument with `"` if it must contain whitespaces. Any redundant whitespaces outside of `"` will be treated as a single whitespace.
 An unknown command will lead to script abort.
+#### `-o` and `-s` Switches
+You can use `-o` and/or `-s` switches on any command, or `--optional` / `--silent` respectively. `-o` Continues on failures of a command, and `-s` will try to suppress all error messages.
+Example: `ask -o -s "Perform this operation (I will completely ignore your response)?"`
