where is this change? is it in the svn? How can I update a server to this change?

I think it has something to do with the dmginfo or something, this is in it's own file.

print("success")
function crippleLegsToggle(ply, toggleBool)

	if toggleBool == true then
		ply:SetWalkSpeed(1)
	end
	
	if toggleBool == false then
		ply:SetWalkSpeed(250)
	end
end

function crippleArmsToggle(ply, toggleBool)

	if toggleBool == True then
		ply.StripWeapon(ply:GetActiveWeapon())
	end
end	
		
		
		
function crippleLimbs(ply, hitgroup, dmginfo)
		-- Lets cripple their legs first
		if (hitgroup == HITGROUP_LEFTLEG or
			hitgroup == HITGROUP_RIGHTLEG) then
			
			--If they were shot in the leg (or they fell) then lower their leg health
			if ply.legHealth != 0 and ply:HasEquipmentItem(EQUIP_ARMOR) == false then 
				ply.legHealth = ply.legHealth - dmginfo.GetBaseDamage()/2
			end
			--When their leghealth is zero? Cripple them
			if ply.legHealth == 0 or dmginfo:IsFallDamage() then
				print("Got this far...")
				crippleLegsToggle(ply, true)
			end
			
		end
		
		if (hitgroup == HITGROUP_LEFTARM or
		        hitgroup == HITGROUP_RIGHTARM) then
				
			if ply.armHealth !=0 and ply:HasEquipmentItem(EQUIP_ARMOR) == false then
				ply.armHealth = ply.armHealth - dmginfo.GetBaseDamage()/2
			end
			if ply.armHealth == 0 then
				crippleArmsToggle(ply, true)
			end
		end
end
	
hook.Add("EntityTakeDamage", "CrippleLimbHook", crippleLimbs(ent, ent:LastHitGroup() or HITGROUP_GENERIC, dmginfo))
		

Also in player.lua

armHealth == 50
legHealth == 50

How would i change the accuracy of a gun, just for one person? That is, when a 'crippled' function gets sent, it makes the ply's weapon half as accurate. Sorry if that is a bit vague  :P
