	// built-in groups. UseOpsworksSecurityGroups has the following settings:
	//
	//    * True - AWS OpsWorks Stacks automatically associates the appropriate
	//    built-in security group with each layer (default setting). You can associate
	//    additional security groups with a layer after you create it, but you cannot
	//    delete the built-in security group.
	//
	//    * False - AWS OpsWorks Stacks does not associate built-in security groups
	//    with layers. You must create appropriate EC2 security groups and associate
	//    a security group with each layer that you create. However, you can still
	//    manually associate a built-in security group with a layer on. Custom security
	//    groups are required only for those layers that need custom settings.
