 ## Flags

 - `-w` or `-wait`: Time to wait in between refreshes (default is 10 seconds).
+- `-l` or `-log`: Send the output to a file.
+- `-m` or `-maxtime`: Sets a maxmium time for the program to try set Attendance (default is -1 (forever)).
+- `-r` or `-replace`: Forces the program into replacing the existing saved password.
+- `-v` or `-verbose`: Shows addicional info.
