Moontool
John Walker's moontool.c astronomical calculation routines, extracted and ported to Rust.
Original
The original versions, moontool and moontoolw, are available at John Walker's fourmilab.ch.
Backup copies are included in the original/
directory of this repository.
License
Walker's program is in the public domain, and so is this project.
In Walker's words:
Do what thou wilt shall be the whole of the law.
CLI
This version includes functions that compute info about the Moon, in a way similar to the original program.
The CLI wraps these functions.

Installation
# CLI, either of:
cargo install moontool
cargo install --git https://github.com/qrichert/moontool.git
# Library
cargo add moontool
This sets up both the CLI:
$ moontool --help
And the library:
use moontool::moon::MoonPhase;
let phase = MoonPhase::now();
