- * A tiled window manager for the terminal.
- *
- * It provides a virtual screen that can be scrolled horizontally and may carry
- * any number of windows to be appeared, disappeared, resized and moved around.
- * They have borders and a title bar and are positioned automatically.
- *
- * Windows can be any width between 1 and 2^16 cells. The virtual screen grows
- * with them as needed -- but only horizontally and only up to 2^16 cells. Their
- * height is limited by the height of the terminal screen (maximum 2^16 cells).
- *
- * Windows' positioning can be influenced only indirectly: by resizing them, and
- * by shifting their relative position inside the (currently invisible) chain
- * that the window manager treats their plurality as. The first window goes into
- * the top left corner of the virtual screen. Further windows are fitted as
- * left-aligned as possible below their (chain-wise) closest predecessor that
- * thrones over enough space to contain them and that is open to the right. If
- * that fails, they're fitted up-right to the window with the rightmost border.
- *
- * TODO: Think up a more intuitive window positioning algorithm.
