Why do you think they had to invent the seals?

Sealead letters can be resealed.

zsh is my favorite for personal use. I set it up to show the last command that matches what you have so far (so if you regularly ssh to some machine, typing ssh shows the last ssh command you used). I also made it so that certain things change color, commands are green, improper commands are red, etc.

What language is this?
