Tpp stands for text presentation program and is an ncurses-based presentation tool. The presentation can be written with your favorite editor in a simple description format and then shown on any text terminal that is supported by ncurses - ranging from an old VT100 to the Linux framebuffer to an xterm.
It supports color, LaTeX output of presentation, sliding in text, a command prompt and additional cool features.
The package also installs syntax highlighting modes/add-ons for emacs and vim. To enable the vim add-on, the package vim-addon-manager needs to be installed, too.
