**Caveman is released under the permissive MIT License.**

The caveman project by Julius Brussee is an open-source repository governed by a straightforward licensing model. Understanding the caveman license is essential for developers who want to use, modify, or distribute the code in their own applications. According to the JuliusBrussee/caveman source code, the project adopts this widely-used permissive license to maximize flexibility for end users.

## MIT License Terms Explained

The `LICENSE` file in the repository root contains the full legal text of the MIT License. This license is favored in the open-source community for its minimal restrictions and commercial-friendly terms.

### Permissive Usage Rights

The caveman license grants you the freedom to **use, copy, modify, merge, publish, distribute, sublicense, and sell** the software. Unlike copyleft licenses such as GPL, the MIT License imposes no requirement to disclose source code for derivative works. This makes Caveman suitable for both open-source and proprietary projects without forcing architectural decisions based on licensing constraints.

### Liability Disclaimer

As stated in the `LICENSE` file, the software is provided **"as is"**, without warranty of any kind. This protects the author, Julius Brussee, from legal claims arising from the use of the software, while allowing users to assume full responsibility for their implementations.

## Where the Caveman License is Declared

The MIT License is declared consistently across multiple files in the JuliusBrussee/caveman repository:

- **`LICENSE`** — Contains the full MIT license text and copyright notice.
- **[`package.json`](https://github.com/JuliusBrussee/caveman/blob/main/package.json)** — Declares `"license": "MIT"` for npm, yarn, and other package managers to automatically detect compliance.
- **[`README.md`](https://github.com/JuliusBrussee/caveman/blob/main/README.md)** — Displays the license badge and references usage terms.
- **[`INSTALL.md`](https://github.com/JuliusBrussee/caveman/blob/main/INSTALL.md)** — References the license for compliance during installation.
- **[`SECURITY.md`](https://github.com/JuliusBrussee/caveman/blob/main/SECURITY.md)** — States the MIT licensing in the context of security policies.

## Practical Implementation Examples

When integrating Caveman into your own projects, proper attribution ensures compliance with the caveman license terms.

### Adding the MIT Badge to Documentation

Include this badge in your [`README.md`](https://github.com/JuliusBrussee/caveman/blob/main/README.md) to indicate your project uses Caveman under MIT terms:

```markdown
[![License: MIT](https://img.shields.io/badge/License-MIT-yellow.svg)](https://github.com/JuliusBrussee/caveman/blob/main/LICENSE)

```

### Including License Headers in Source Files

Add this header to new JavaScript files that incorporate Caveman code:

```javascript
/**
 * © 2026 Julius Brussee
 * Licensed under the MIT License – see LICENSE file for details.
 */

```

### Verifying the License Programmatically

You can confirm the license field using Node.js:

```javascript
const fs = require('fs');
const pkg = JSON.parse(fs.readFileSync('package.json', 'utf8'));
console.log(`Project license: ${pkg.license}`); // → MIT

```

### Proper package.json Configuration

When publishing a package that depends on Caveman, ensure your [`package.json`](https://github.com/JuliusBrussee/caveman/blob/main/package.json) includes the license field:

```json
{
  "name": "your-project",
  "version": "1.0.0",
  "license": "MIT",
  "dependencies": {
    "caveman": "^1.0.0"
  }
}

```
