FIXME installing and linking instrunctions here
--------------------------------------
* Comment out the following functions in defs.qc
sound, aim, setspawnparms
--------------------------------------
* Add this to worldspawn() in world.qc, right at the very top, before InitBodyQue();
BotInit();  // FrikBot
--------------------------------------
* add this line to StartFrame() in world.qc, at the very top
BotFrame(); // FrikBot
--------------------------------------
* Add these two lines to PlayerPreThink in client.qc at the very top
if (BotPreFrame()) // FrikBot
	return;
--------------------------------------
* Add this line to PlayerPostThink in client.qc at the very top
if (BotPostFrame()) // FrikBot
	return;
--------------------------------------
* Add the following line to the very top of Client Connect in client.qc
ClientInRankings(); // FrikBot
--------------------------------------
* Add these lines to the very top of ClientDisconnect in client.qc
ClientDisconnected(); // FrikBot
