- *  fogcoord.c
- *
- *  This program demonstrates the use of explicit fog 
- *  coordinates.  You can press the keyboard and change 
- *  the fog coordinate value at any vertex.  You can
- *  also switch between using explicit fog coordinates 
- *  and the default fog generation mode.
- * 
- *  Pressing the 'f' and 'b' keys move the viewer forward
- *  and backwards. 
- *  Pressing 'c' initiates the default fog generation.
- *  Pressing capital 'C' restores explicit fog coordinates.
- *  Pressing '1', '2', '3', '8', '9', and '0' add or
- *  subtract from the fog coordinate values at one of the
- *  three vertices of the triangle.
