-  rel="nofollow">OptimalControl.jl</a>&nbsp;package is the root package of the&nbsp;<a
-  href="https://github.com/control-toolbox">control-toolbox ecosystem</a>. The control-toolbox
-  ecosystem gathers Julia packages for mathematical control and applications. It aims
-  to provide tools to model and solve optimal control problems with ordinary differential
-  equations by direct and indirect methods.</p>
