Danial Vik has presented a tour de force feature rich X11-based
racing game that fit within the contest size limits. Take a
glace at the feature list he provided below. Amazing!

### Build and Run
Build and Run
=============
Compile the source code and link x libraries if necessary.
The program takes three options which have to be typed in a specific
order as described below.

Note that the order in which the argument characters are entered is
important. It is for example not possible to type ./vik1 da. (Well it is
possible, but the result will not be as expected.)

The space key accelerates the car. Releasing the space key slowly
reduces the speed. The left and right arrow keys are used to steer the
car.

### Obfuscation
The main obfuscation is the fact that the program is extremely compact.
There are a few things I didn't want to do, e.g. define #define to a
single letter to save some space, or to remove casts to save some space.
Obfuscation
===========
The program uses a lot of variables. In fact, all letters a-z are used
and most letters A-Z.

The constants are chosen very carefully and thy have multiple purposes,
e.g. a constant can be both the length of the track and a color.
The program uses a lot of variables. In fact, all letters a-z are used
and most letters A-Z.
Most of the code is kept inside five for loops without body. Each for
loop does many things. One for loop draws all cars by restarting a
couple of times. Another draws the road, mountains, and the sun.

Main is called recursively. The return value and output depends on the
arguments. main can return the current time, draw lines and of course be
the entrypoint of the application.

The program frequently uses the ? operator mainly to save space but it
makes the program more obscure.

### Compiler warnings
The program frequently uses the ? operator mainly to save space but it
makes the program more obscure.
There are no compiler warnings when compiling with -ansi but there are
quite many warnings from lclint. Mainly because the program is very
optimized for code size.
### Limitations
Compiler warnings
=================
The program only compiles and runs on X based systems.

The program requires a display with 24 bit color depth. It also assumes
that the byte order of the colors are as on my Linux PC. That is, The
colors are represented by a 32 bit value where the bytes (from high to
low) are { 0, RED, GREEN, BLUE }.
