  ArchiveStreamProvider | Creates Archive `ArchiveInputStream`s and `ArchiveOutputStream`s.

- Class Summary
  Class | Description

  ArchiveOutputStream | Archive output stream implementations are expected to override the `OutputStream.write(byte[], int, int)` method to improve performance.
  ArchiveStreamFactory | Factory to create Archive[In|Out]putStreams from names or the first bytes of the InputStream.
  Lister | Simple command line application that lists the contents of an archive.

- Exception Summary
