-Enable experimental Source Map v3 support for stack traces.
+When using a transpiler, such as TypeScript, strack traces thrown by an
+application reference the transpiled code, not the original source position.
+`--enable-source-maps` enables caching of Source Maps and makes a best
+effort to report stack traces relative to the original source file.

+Overriding `Error.prepareStackTrace` prevents `--enable-source-maps` from
+modifiying the stack trace.
