This directory contains utility programs and development tools for zlib-ng. These utilities help with compression testing and generating of internal tables.

minigzip is in addition to being used for testing also popularly used as a simpler but faster alternative to gzip.

• minigzip.c: A lightweight implementation of the standard gzip compression and decompression tool.
• minideflate.c: A basic demonstration program for testing raw deflate compression and decompression streams.
• makefixed.c: Generates the static Huffman codes table used for fixed deflate blocks (inffixed_tbl.h).
• maketrees.c: Generates the static tree tables and compile-time structures used for Huffman tree construction (trees_tbl.h).
• makecrct.c: Generates the precomputed CRC-32 and CRC-32-Fold lookup tables used to accelerate checksum calculations (crc32_braid_tbl.h).
