## Overview

A Dart library to encode and decode various archive and compression formats.

The library has no reliance on `dart:io`, so it can be used for both server and
web applications.

The archive library currently supports the following decoders:

- Zip (Archive)
- Tar (Archive)
- ZLib [Inflate decompression]
- GZip [Inflate decompression]
- BZip2 [decompression]
- XZ [decompression]

And the following encoders:

- Zip (Archive)
- Tar (Archive)
- ZLib [Deflate compression]
- GZip [Deflate compression]
- BZip2 [compression]
