"Old Unzip" - A collection a public domain or MIT licensed single-header-file C/C++ libraries to help decompress ZIP files. There are three libraries: * ozunshrink.h: "shrink" compression (method 1) * ozunreduce.h: "reduce"/"expand" compression (methods 2-5) * unimplode6a.h: "implode"/"explode" compression (method 6) For more information, see the individual readme files, and the .h files. === Other files in this project === ozdemo.c is a sample program that uses the libraries, and implements a minimal ZIP parser. It will extract up to 25 supported member files from a ZIP file, naming the output files "demo.???.out". testexamplecode.c helps verify that the #ifdefed-out example code in the libraries works. ozft.c makes it easier to do fuzz testing with afl-fuzz.
