## Description

The ReVanced Patcher is a framework designed for modifying compiled Android application binaries. It functions as an engine for injecting custom code, altering bytecode, and updating resources directly within package files without requiring access to the original source code.

The project distinguishes itself through a modular system that organizes modifications into independent, reusable units. These patches are managed through a dependency-aware execution process that ensures modifications are applied in the correct order, allowing for consistent behavior changes across different application versions and environments.

The toolset provides comprehensive capabilities for binary instrumentation, including the ability to disassemble instructions into an intermediate representation for modification before reassembling them. It also handles the decoding and rebuilding of resource tables and application archives, ensuring that the internal structure and cryptographic integrity of the modified packages are maintained.
