9 This function loads and executes a lua file specified by a given path. If an "id" or "params" are provided, the param.get_id(...) and/or param.get(...) functions will return the provided values during execution. The lua routine must return true, false, nil or a string. In case of true or nil, this function returns the string "ok", in case of false, this function returns "error", otherwise the string returned by the lua routine will be returned by this function as well.
