PNG decoder/encoder in pure Rust.

It contains all features required to handle the entirety of [the PngSuite by
Willem van Schack][PngSuite].

## pngcheck

The `pngcheck` utility is a small demonstration binary that checks and prints
metadata on every `.png` image provided via parameter. You can run it (for
example on the test directories) with

```bash
cargo run --release --example pngcheck ./tests/pngsuite/*
```
