## Description

This project is a set of specialized tools for installing archive packages and programmatically parsing or validating software version constraints. It functions as a PHP version comparison library and a semantic versioning parser designed to handle the requirements of software dependency management.

The system includes a PHP archive installer that downloads and deploys Phar packages from repositories, GitHub, or direct URLs. It uses a semantic version constraint validator to ensure that installed versions satisfy specific requirements defined by mathematical, caret, or tilde operators.

Additional capabilities cover programmatic version parsing, the comparison of release order with support for pre-release labels, and the resolution of package aliases to specific download sources.
