    zlib: Add Industrial Strength Compression to Your C/C++ Apps

    The zlib compression library enables developers to integrate lossless compression into their application suites with ease. The benefits are saved time, space, and therefore money.

    A Simple Yet Highly Efficient Compressing Technique

    Redundancy is very high in any text material. Simple ordering can lead to compression ratios up to 20:1 in directory listings.
