argparse-longhelp v1.0.3

Small helper function for argparse to add extra help text.

This makes use of argparse internals, but the project's code is stable enough and is unlikely to change in a way that would break this.

Example

const parser = new ArgumentParser({
  version: '1.0.0',
  addHelp: true,
  description: 'Regular description',
  epilog: 'Copyright'
})
addLongHelp(parser, 'A long explanation')
