- * Higher level routines for dealing with windows.
- *
- * There are two types of windows: user window, and information window.
- * User windows are the ones with a pty and shell. Information windows
- * are for displaying error messages, and other information.
- *
- * The windows are doubly linked in overlapping order and divided into
- * two groups: foreground and normal. Information
- * windows are always foreground. User windows can be either.
- * Addwin() adds a window to the list at the top of one of the two groups.
- * Deletewin() deletes a window. Front() moves a window to the front
- * of its group. Wwopen(), wwadd(), and wwdelete() should never be called
- * directly.
