## Missing features
## Known issues
This module does not yet support:
- `resolve.alias` settings whose values are absolute paths might not work
- `resolve.modulesDirectories` only searches the directory containing your package.json file, not all ancestors of current file
- `resolve.alias` settings whose values are absolute paths
