# @micosmo/aframe/startup

Aframe system that manages the dispatching of queued tasks that cannot be performed until the application and aframe elements have been loaded.
Two queues are supported. The *onLoaded* queue is dispatched immediately after the system *loaded* event is received, The second *afterLoaded* queue is dispatched after all the *onLoaded* processing is complete.

The *startup* system has no API and purely listens for the *loaded* event. Queueing of tasks is via module exports.
