gzip Compression / Decompression Category for NSData & NSFileManager

This library is no longer being maintained. As of iOS 13+ and macOS 10.15+, Foundation provides equivalent functionality through APIs like compressed(using:) and decompressed(using:).

You can install Godzippa via CocoaPods, by adding the following line to your Podfile:

pod 'Godzippa', '~> 2.1.1'

Run the pod install command to download the library and integrate it into your Xcode project.

To use Godzippa in your Xcode project using Carthage, specify it in Cartfile:

github "mattt/Godzippa" ~> 2.1.1

Then run the carthage update command to build the framework, and drag the built Godzippa.framework into your Xcode project.

Copy the .h and .m files in the Sources directory to your project. In the "Link Binary With Libraries" Build Phase of your Target, add libz.dylib.
