Travis and Appveyor seem to be out of git sync with errors like:

 1) bin/builder-core builder run runs a <root>/package.json command:
     Error: Cannot find module './utils/setup'

closing and re-opening to hopefully kick. (Just a wild stab in the dark)

@jstrimpel -- At long last, builder pre|post is all ready to go! I've refactor the entire execution model and improved that along the way too (particularly with handling errors / early exits when things go wrong).

Let me know how it looks on your end. From here, I'm going to do three short additional changes before releasing a new MAJOR:

• Add a debug log level.
• Default to --quiet=true for toning down all the builder.
• Add an engines restriction to node4+ (I won't refactor the code to node4+ now, just want to get the breaking change out of the way)

Released in builder@4.0.0
