This Python code is a simplified validation tool targeting Python package files for type annotations and setup configuration files as part of packaging standards compliance. It's intended to run benchmarks for performance metrics and self-test validations.

---

# README.md

## Description:
The `benchmark.py` script provides a basic benchmark test for a Python project validation tool against predefined rules focusing on typing correctness (PEP 484) and following the package specifications guidelines (PEP 517/518). This script is a demonstration of how to modularize checks within the Python Standard Library constraints.

## Installation:
No external libraries installation required as it uses built-in modules only.

## Usage:
- `benchmark.py` runs validation checks on type annotations and packaging compliance metrics.
- Output includes VRAM_usage, throughput in TOKENS_PER_SEC, and verification status (PASS/FAIL).

## Test Details
The following assumptions are made about a sample directory containing Python code and package files:
- Each Python file should have proper type hints as per PEP 484 guidelines.
- A setup.cfg must exist with a sane minimum structure to assert packaging best practices.
