## Overview

A small command-line ELF converter: it reads a 64-bit little-endian relocatable ELF, validates its header, extracts sections, and writes a minimal executable containing the .text section. The main workflow is visible in fluid.cpp; utility file operations are shown separately. The README is empty, so no additional product capabilities are documented.

Main entry points: [`fluid.cpp`](https://github.com/sfluorine/fluid/blob/master/fluid.cpp) (Converter entry), [`utils.cpp`](https://github.com/sfluorine/fluid/blob/master/utils.cpp) (File utilities)
