### Brief description

A refactoring of the IAU SOFA library to modern Fortran standards.

This is based on the 2019-07-22 Fortran 77 SOFA Release.

### Status

[![last-commit](https://img.shields.io/github/last-commit/jacobwilliams/astro-fortran)](https://github.com/jacobwilliams/astro-fortran/commits/master)

### Compiling

A [Fortran Package Manager](https://github.com/fortran-lang/fpm) manifest file is included, so that the library and tests cases can be compiled with FPM. For example:

```
fpm build --profile release
fpm test --profile release
```

To use `astro-fortran` within your FPM project, add the following to your `fpm.toml` file:
```toml
[dependencies]
astro-fortran = { git="https://github.com/jacobwilliams/astro-fortran.git" }
```

To generate the documentation using [FORD](https://github.com/Fortran-FOSS-Programmers/ford), run:

```
ford astro-fortran.md
```
