> 1. Create a directory in your project:
> {noformat}
> mkdir blah
> {noformat}
> 2. Create an empty {{pkg.yml}} file in the directory:
> {noformat}
> touch blah/pkg.yml
> {noformat}
> 3. Build a non-split-image target.
> Newt will compile everything twice, as if it were building a split image.  Then it will fail in an unpredictable way, e.g.:
> {noformat}
