These are the developer test clients that i've made available for multiplayer gaming, along with a few custom options:
// Number of bots to spawn?
set svr_bots 0 // Default = 0
// Class type: assault, specops, heavygunner, demolitions, sniper, random
set svr_bots_class random // Default = random
// Team type: allies, axis, autoassign
set svr_bots_team autoassign // Default = autoassign
