A modern and more featured “echo”

I posted this because it interested me, but I have nothing to do with the project. I love shells, use `zsh`, mostly, but like to play around with other options.

I was curious about:

      It has more features than echo, but it is not necessarily faster.

Any idea how far off it is from the performance of `echo` or the equivalent when calling `echo` from `zsh` or other shells where `echo` is a builtin? The support for color output is interesting; reminds me of `Write-Host` in PowerShell. Curios if ANSI codes are suppressed when piping (like `grep`/`ls` would do when `--color=auto` is passed) and I like the `delay`, even though I can't find a use for it other than making things look like they're coming out of a 1200 baud modem :)
