This allows you to drag and drop extensions into vBot without editing the vBot cavebot.lua file to load them.
Find tile CONFIGNAME\vBot\cavebot.lua
Find --dofile("/cavebot/extension_template.lua")
And add the code below on the line below it.
Create a folder called "extensions" in path CONFIGNAME\vBot\cavebot

--dofile("/cavebot/extension_template.lua")
local extFiles = g_resources.listDirectoryFiles("/bot/" .. configName .. "/cavebot/extensions", false, false)
for i, file in ipairs(extFiles) do
  local ext = file:split(".")
  if ext[#ext]:lower() == "lua"  then
    dofile('/cavebot/extensions/'..file)
  end
end
