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

### Compiling

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

```

fpm build --profile release

fpm test --profile release

```

To use `fortran-mach` within your fpm project, add the following to your `fpm.toml` file:

```toml

[dependencies]

fortran-mach = { git="https://github.com/jacobwilliams/fortran-mach.git" }

```

Or, to use a specific version:

```toml

[dependencies]

fortran-mach = { git="https://github.com/jacobwilliams/fortran-mach.git", tag = "0.1.0" }

```
