 ## Introduction
 
 `ez-a-sync` is a Python library that enables developers to write both synchronous and asynchronous code without having to write redundant code. It provides a decorator `@a_sync()`, as well as a base class `ASyncGenericBase` which can be used to create classes that can be executed in both synchronous and asynchronous contexts.
