-Description: Avoid error for incorrect root directory
- Avoid error for incorrect root directory. Test/build.js expects
- "bluebird". When building in Debian, the root directory
- changes (e.g. node-bluebird-3.4.6). Although this should not matter for
- Debian (the check is probably just in case a developer tries to
- run the tests outside of the root directory), this patch checks that
- at least the first 13 characters of the root directory contain
- "node-bluebird".
