# Name:        Player Logger
# Purpose:     Logs when players are on and off the server. Can find what
#              players were on the server during a specific time interval by
#              using /findusers timeinterval1 timeinterval2 day month year
#              Each time interval should be in the form hour:minute:second
#              If the intervals are the same it finds the users logged on at
#              that point in time. If day, month, or year is left out it will
#              use the current day, month, or year at the time the command is
#              used. Logs are saved on disconnect to the file specified at the
#              beginning of this script.
#
#              WARNING: YOU MUST CTRL-C EXIT THE SERVER FOR THE LOG TO SAVE. IT
#              WILL NOT SAVE IF YOU JUST EXIT THE WINDOW
