# Redacted Software Archive
Yet Another Archival Format :D
The ReArchive project is a lightweight C++ library designed for creating, managing, and extracting archive files. It provides a foundation for bundling multiple files and directories into a single archive, ideal for game assets (mod distribution), application deployments, and many more tasks. Included with the library is `rsarchive`, a command-line application demonstrating ReArchive's capabilities and providing a general-purpose archive management tool.
## Features
* General
* Custom bespoke archive format.
* Included CLI archive program.
* C++20 API for integrating archives into your project.
* Public Domain Source Code, Format, & Application.
* **ZERO** dependencies. Just C++ and CMake.
* Library API Features
* Bundle files together for easier distribution.
* Integrate easily into your C++ project.
* Cross-platform: Designed with Redacted Software signature portability, simplicity, and
* Archive Format
* Custom, stream-friendly archive format.
* Designed for efficiency and extensibility.
* Efficient file retrieval even from large archives.
* Lightning fast. (See Benchmarks.)
* rsarchive Application:
* Robust command-line utility.
* Create, Extract, Inspect, Modify, and Validate archive files.
* Append and remove files individually.
* Supported on Windows & Linux.
* Designed to be extended and modified.
