"""<H2>Introduction</H2>
You are the proud new operator of a M-375 Pflanzarr Tank. Your tank is
equipped with a powerful laser cannon, independently rotating turret
section, up to 10 enemy detection sensors, and a standard issue NATO hull.
Unfortunately, it lacks seats, and thus must rely own its own wits and your
skills at designing those wits to survive.
<H2>Programming Your Tank</H2>
Your tanks are programmed using the Super Useful Command and Kontrol language,
the very best in laser tank AI languages. It includes amazing feature such
as comments (Started by a #, ended at EOL), logic, versatility, and
semi-colons (all lines must end in one). As with all new military systems
it utilizes only integers; we must never rest in our
diligence against the communist floating point conspiracy. Whitespace is
provided by trusted contractors, and should never interfere with operations.
<P>
Your program should be separated into Setup and AI commands. The definitions
section lets you designated the behaviors of its sensors and memory.
Each setup command must begin with a '>'. Placing setup commands after
the first AI command is a violation of protocol.
Here are some examples of correct setup commands:
<pre class="docs">>addsensor(80, 90, 33);
>addsensor(50, 0, 10, 1);
>addtimer(3);</pre>
The AI section will act as the brain of your tank. Each AI line is
separated into a group of conditions functions and a group of action
functions. If all the conditions are satisfactory (true), all of the actions
are given as orders. Conditions are separated by ampersands, actions separated
by periods. Here are some examples of AI commands:
<pre class="docs">
sensor(1) & sensor(2) & fireready() : fire();
sensor(0,0)&sin(5): move(40, 30) . turretcw(50);
sensor(4) & random(4,5) : led(1).settoggle(0,1);</pre>
Your tank will check its program each turn, and attempt to the best of its
abilities to carry out its orders (or die trying). Like any military mind,
your tank may receive a plethora of often conflicting orders and information.
This a SMART TANK, however. It knows that the proper thing to do with each
subsystem is to have that subsystem follow only the last order given each turn.
