/*
   STRUCTURE OF A DAT FILE
   0:  day of the record
   1:  count of visitors for the day
   2:  count of total visitors ever
   3:  the date of the best day count
   4:  count at the best date

   How this work?
   When the date change, the value is set to 1 and
   if the counter is that of the home page,
   the stat file is updated from all .dat files
   (counters of each page).
   If the counter is not that of the home page,
   the data file of the main page is loaded
   and if it its day has changed,
   the day of the current counter is changed also
   and the count is set to 1.
