Copy/Rename files with Composer+PHP

		//The above code was built to work cross-platform, which is why it looks a bit inefficent in how it does things (Can't use variables).
		//Linux requires the use of single quotes (but has support for double quotes), and Windows only supports double quotes.
		//	Sadly, Linux uses $ for bash variables within double quotes, which essentially restricts us from using any sort of variable.
		//If there is a better way of doing this cross-platform, please let me know.
