# shiva::entt

## Purpose

This module simply makes a **namespace alias** to use [EnTT](https://github.com/skypjack/entt).

This module is represented by a cmake interface library that facilitates its handling through other modules. 

This module contains also helpers for using EnTT across dll boundaries (used internally).

But also small changes to avoid situations of ambiguous code related to scripting
