  {bold Usage}: {yellow namesake} [word] [options]

    Generate a list of words that just so happen to also
    be available as npm package names.

    Optionally, you can use any word as input to find
    related words and terms.

  {bold Options}:

    -l, --limit   <n>  Limit the number of results returned (defaults to 50)
    -h, --help         Show this help message
    -v, --version      Output the {yellow namesake} version number
  \n
