+This option is similar in intent to yargs's `exitProcess()` function,
+except applied more granularly.
+
+Normally, [runProgram](../functions/runProgram.md) never throws and never calls `process.exit`,
+instead setting `process.exitCode` when an error occurs.
+
+However, it is at times prudent to kill Node.js as soon as possible after
+error handling happens. For example: the execa library struggles to abort
+concurrent subcommand promises in a timely manner, and doesn't prevent them
+from dumping output to stdout even after Black Flag has finished executing.
+To work around this, we can set `dangerouslyFatal` to `true`, forcing Black
+Flag to call `process.exit` immediately after error handling completes.
+
+More generally, enabling `dangerouslyFatal` is a quick way to get rid of
+strange behavior that can happen when your microtask queue isn't empty
+(i.e. the event loop still has work to do) by the time Black Flag's error
+handling code completes. **However, doing this without proper consideration
+of _why_ you still have hanging promises and/or other microtasks adding
+work to the event loop can lead to faulty/glitchy/flaky software and
+heisenbugs.** You will also have to specially handle `process.exit` when
+running unit/integration tests and executing command handlers within other
+command handlers. Tread carefully.

+
+By default, if an Error object is passed to `CliError`, that

+
+Use this option to override this default behavior and instead set

+More generally, enabling `dangerouslyFatal` is a quick way to get rid of
+strange behavior that can happen when your microtask queue isn't empty
+(i.e. the event loop still has work to do) by the time Black Flag's error
+handling code completes. **However, doing this without proper consideration
+of _why_ you still have hanging promises and/or other microtasks adding
+work to the event loop can lead to faulty/glitchy/flaky software and
+heisenbugs.** You will also have to specially handle `process.exit` when
+running unit/integration tests and executing command handlers within other
+command handlers. Tread carefully.
