%description
fish is a fully-equipped command line shell (like bash or zsh) that is
smart and user-friendly. fish supports powerful features like syntax
highlighting, autosuggestions, and tab completions that just work, with
nothing to learn or configure.

fish 4.x is a from-scratch rewrite in Rust.
