import { HyperdbHelper } from '../index.js'
import mri from 'mri'
import dedent from 'string-dedent'

const flags = mri(process.argv.slice(2), {
  alias: {
    examples: 'e',
    help: 'h'
  },
  default: {
    examples: false
  }
})

const args = flags._
const cmd = args.shift()

if (!cmd || cmd === 'help' || flags.help) {
  console.log(dedent`
    # hyperdb-helper
