This is a benchmark between multiple programs doing the task specified here (without file and argument parsing).
Executing run.sh builds the programs (with release profile) and then benchmarks them
with Rust's integrated bencher.
As Rust's integrated bencher is unstable, a nightly toolchain is required. Recommended
installation method is obtaining rustup.rs (a Rust toolchain manager) and
running rustup override add nightly in this directory.
More versions are welcome! Just send a pull request. I can take care of adding it to the benchmark.
Notes:
- The awk and Python versions are currently doing not the exact same work as the other versions.
