var Redux 				= require('redux');
,	reducerCollection 	= require('../actions/reducers')
,	McFly 				= require('../my-mcfly')

,	combinedReducers 	= combineReducers(reducerCollection)
,	_state 				= _getState() // however you'll get it
,	MsgStore 			= McFly.createStore({
		getState: function() {
			return this.state;
		}
	}, 	function(action) {
			// switch(action.type) { ... }
			// outsource your reducers and use:
			combinedReducers(_state, action);
			// standard McFly procedure
			MsgStore.emit('change');
			return true;
		}
	)
;
module.exports 	= MsgStore;
