## What it is
A Composer plugin for PHP that provides fast, zero-IO access to the installed version numbers of Composer dependencies. It compiles package version data from composer.lock at install time so lookups at runtime require no file reads.

## Use cases
- get installed composer package version numbers in php
- check dependency version at runtime without file io
- embed package versions in generated assets or artifacts
- log the versions of composer dependencies my app uses
- php library to read versions from composer.lock

## When to choose
- you need dependency version info at runtime with no IO overhead
- you generate code or assets that must reflect installed package versions
- you want a tiny, stable composer addon maintained by a well-known PHP contributor

## When to avoid
- you are not using Composer to manage PHP dependencies
- you only need version info at build time and can parse composer.lock yourself
- you are on PHP with Composer 2.1+ and can use the built-in Composer\InstalledVersions API instead
