// The aurora is a web-based beanstalkd queue server console written in Go
// and works on macOS, Linux and Windows machines. Main idea behind using Go
// for backend development is to utilize ability of the compiler to produce
// zero-dependency binaries for multiple platforms. aurora was created as an
// attempt to build very simple and portable application to work with local or
// remote beanstalkd server.
