## Requirements & limits

- Use the native C/C++ library or a supported language binding; build instructions cover Windows and Unix-like hosts, with vcpkg as an alternative installation route.
- The project offers GPLv2 with its EXCEPTIONS-CLIENT terms or a commercial license. It is an assembler framework; decompilation and executable reconstruction require other tools.
