These graphical tools will help with the customization of the templates for HTML PLAIN. Some dotfiles with a similar structure can also be edited after making some small adjustments to the programs (i. e. to the input and output filter).

console othello is an Othello-style board game running on a text console. The AI is not brilliant and the game is simple, but several improvements are planned, including support for a web version and network play.

ControlFreak is a scriptable toolbar application. You write scripts describing the layout and what you want the toolbars to do, and ControlFreak creates the toolbars. The toolbar components run shell commands when activated, and you can also use the state of various toolbar components (ie the contents of a text box or whether a toggle button is up or down) to influence what shell commands are run and what arguments they use.
