Put a little spinner on process.stderr, as unobtrusively as possible.
var spinner = require("char-spinner")
// All options are optional
// even the options argument itself is optional
var interval = spinner(options)
// the return value is the interval.
// to stop the spinner, you can just clearInterval on it
clearInterval(interval)
// then to restart it again, just call the function again
interval = spinner(options)Usually the defaults are what you want. Mostly they're just configurable for testing purposes.
