## Overview

RePairip is a command-line Android protection-removal and APK repacking tool. Its main workflow takes an APK, patches protected DEX and manifest content, writes a repacked APK, and can correct DEX CRCs; optional translation and root-device installation extend that workflow. A separate package mode performs native-library surgery, with ELF parsing and patching as its core. The README also advertises VMRunner snapshot dumping. The sampled sources show only parts of the main orchestration and native patching, so uncertain internal links are omitted.
