Snzip is one of command line tools using snappy. This supports several file formats; framing-format, old framing-format, hadoop-snappy format, raw format and obsolete three formats used by snzip, snappy-java and snappy-in-java before official framing-format was defined. The default format is framing-format. The default format was changed to framing-format in 1.0.0. Set --with-default-format=snzip as a configure option to use obsolete snzip format as the default format as before.
