This Go library allows you to easily unpack the following files using magic numbers:

• tar.gz
• tar.bzip2
• tar.xz
• zip
• tar

Unpack a file:

    file, _ := os.Open(test.filepath)
    err := unpackit.Unpack(file, tempDir)

Unpack a stream (such as a http.Response):

    res, err := http.Get(url)
    err := unpackit.Unpack(res.Body, tempDir)
