Zlib

This module provides access to the zlib library. Zlib is designed to be a portable, free, general-purpose, legally unencumbered – that is, not covered by any patents – lossless data-compression library for use on virtually any computer hardware and operating system-

The zlib compression library provides in-memory compression and decompression functions, including integrity checks of the uncompressed data-

The zlib compressed data format is described in RFC 1950, which is a wrapper around a deflate stream which is described in RFC 1951-

The library also supports reading and writing files in gzip (-gz) format with an interface similar to that of IO. The gzip format is described in RFC 1952 which is also a wrapper around a deflate stream.
