       The "Compress::Snappy" module provides an interface to Google's Snappy (de)compressor.

       Snappy does not aim for maximum compression, or compatibility with any other compression library;
       instead, it aims for very high speeds and reasonable compression. For instance, compared to the fastest
       mode of zlib, Snappy is an order of magnitude faster for most inputs, but the resulting compressed files
       are anywhere from 20% to 100% bigger.

compress
           $string = compress($buffer)

       Compresses the given buffer and returns the resulting string. The input buffer can be either a scalar or
       a scalar reference.

   decompressuncompress
           $string = decompress($buffer)

       Decompresses the given buffer and returns the resulting string. The input buffer can be either a scalar
       or a scalar reference.

       On error (in case of corrupted data) undef is returned.

       This distribution contains a benchmarking script which compares several compression modules available on
       CPAN.  These are the results on a MacBook 2GHz Core 2 Duo (64-bit) with Perl 5.14.2:
