## Usage

To use `checksum` within your `fpm` project, add the following lines to your `fpm.toml` file:

```toml

[dependencies]

checksum = { git="https://github.com/zoziha/checksum" }

```

## Example

```sh

> fpm run --example --all  # run the example

```

```fortran

program example_checksum

    use checksum_module, only: checksum, read_whole_file

    implicit none

100 format(a, t50, i0)

    print 100, "checksum(""hello world""):", checksum('hello world')

    print 100, "checksum(read_whole_file(""./src/checksum.f90"")):", &

        checksum(read_whole_file('./src/checksum.f90'))

end program example_checksum

!> checksum("hello world"):                         436929629

!> checksum(read_whole_file("./src/checksum.f90")): -750348609
