# XZ Utils

XZ Utils is a high-performance data compression library and command-line tools that provide the XZ format, which offers significantly better compression ratios than traditional formats like gzip and bzip2.

## Features

- **High Compression Ratio**: Achieves excellent compression ratios, typically 30-50% better than gzip
- **Multiple Formats**: Supports both the legacy .lzma format and the modern .xz format
- **Integrity Checking**: Built-in CRC32, CRC64, and SHA-256 integrity checks
- **Multi-threading**: Utilizes multiple CPU cores for faster compression/decompression
- **Small Memory Footprint**: Efficient implementation suitable for embedded systems

## Included Tools

- **xz**: Main compression/decompression tool with advanced features
- **xzdec**: Small decompressor for memory-constrained environments
- **lzmainfo**: Displays information about .lzma files
- **lzmadec**: Decompresses legacy .lzma format files
- **Scripts**: Helper scripts for compressed file operations (xzgrep, xzdiff, xzmore, etc.)

## Applications

XZ Utils is widely used in:
- System backup and archiving tools
- Software distribution and packaging
- Embedded systems and firmware
- Data compression for cloud storage and transmission

## License

XZ Utils is released under multiple free software licenses:
- BSD Zero Clause License (0BSD) for most components
- GNU GPL v2/v3 for some components
- GNU LGPL v2.1 for getopt_long functionality in scripts

This package provides the complete XZ Utils suite including libraries, command-line tools, and development headers for integration with other applications.
