File reader in async Rust

This program will print each character of input (from a file or STDIN) to the screen at a speed that will allow you to read along. You can use the -s|--slow or -f|--fast flags to slow it down or speed it up.

Usage: readr [OPTIONS] <FILE>

Options:
  -s, --slow  Go slower
  -f, --fast  Go faster
  -h, --help  Print help
