How to regenerate bindata.go

Run go generate when you add, remove, or change the files in the scaffold directory.

This will generate a new bindata.go file, which you SHOULD commit to the repo. Both the scaffold directory that this file is created from and the file itself belong in the repo. Make changes directly to the scaffold directory and its files, not bindata.go.
