I am trying to create a PHP library which includes other libraries, and I bet I'm missing something fundamental.
Using the AWS PHP SDK as a guide, I'd like to create a library which, after installing with Composer, requires other libraries, yet the entire scope of classes (both from the current library, and required libraries) all become available simply by using require 'vendor/autoload.php;'.
What are the basic requirements to set this up? Is it a matter of configuring composer.json, namespacing in a particular way, or both?
