  We present a toolbox for the continuation of two-dimensional tori in
autonomous dynamical systems and non-autonomous systems with periodic forcing.
A torus is solved as the solution to a boundary-value problem. Truncated
Fourier series and collocation methods are used to discretize the
boundary-value problem. This toolbox is based on the continuation package COCO
(https://sourceforge.net/projects/cocotools/). A few examples are included to
demonstrate the functionality of this toolbox.
