It requires at least two PHP files. One that ACTUALLY DOES WHAT YOU WANT and the library files.

Since you have to write a new PHP file anyway, composer allows you to pull in the latest version (or update it) with semver constraints.

Then you can package it as a phar and call it that way.

This is a library, not a file to run, and so it should have composer support.

Or, if you don't want to package it as a PHAR - since I have no idea how to do that, you'd implement your version in some directory and probably alias a command to it.

TL;DR: This is a library, not a script. It should have composer support.

I don't want to automatically pull the latest version. I would only use this after I studied the code and made sure it is not doing anything harmful. That's why this has to be as simple as possible.

You don't have to. Composer allows you to pick a particular package version if you like, and it's only going to fetch a more recent version if your composer.json permits it and if you explicitly run composer update.
