Mach-O header analysis and editing

macholib is a Python library used for analyzing and editing Mach-O headers, the executable format employed by macOS. It functions primarily as a dependency analysis tool, capable of rewriting dylib references within Mach-O headers to be @executable_path relative. The library is pure Python, platform, and endian-independent, currently at version 1.16.4, with active development and regular releases.
