 Harris uses SDL and a simple graphics toolkit called "libatg" (for A Tiny Gui).  The former can be found at <http://www.libsdl.org> and the latter at <https://github.com/ec429/libatg>.  It also depends (via atg) on the Liberation Mono font, which Debian users can get from the package "fonts-liberation".  SDL packages needed: sdl, sdl-devel, sdl-image, sdl-image-devel, sdl-ttf, sdl-ttf-dev, sdl-gfx, sdl-gfx-dev.
