## What it is
A C++ command-line compiler that converts a simplified C/C++-style source language into small, position-independent, NULL-free shellcode for Windows and Linux (x86 and x64). It generates assembly from its own interpreter and assembles it using the Keystone engine, allowing user-friendly calls to Windows APIs and Linux syscalls.

## Use cases
- compile C-style code into shellcode for Windows x64
- generate NULL-free position-independent shellcode for Linux
- call Windows API functions from shellcode source
- invoke Linux syscalls in generated shellcode
- download and execute a file via shellcode
- test generated shellcode execution from the command line

## When to choose
- you need small custom shellcode for red-team or exploit development on x86/x64 Windows or Linux
- you want to call Windows APIs or Linux syscalls without hand-writing assembly
- you need position-independent, NULL-free shellcode output as a binary file

## When to avoid
- you need variables, pointers, buffers, or API return values - these are unsupported
- you need a production-grade, fully featured compiler - this is an alpha with many limitations
- you target platforms other than x86/x64 Windows and Linux
