This shell implements some features from zsh, some from fish, and some from bash for the sake of learning Rust. This shell really shouldn't be used by anyone over any of the aforementioned shells since it's just a project used to practice learning the language Rust. This shell somewhat acts like a typical Unix shell, and as a result I'm not really sure how it would behave on Windows. Sorry!
NaSH is a portmanteau of "Nate" and "SHell", really not that clever but I thought it had a nice ring to it.
