# Each crontab file entry consists of a line with six fields, separated
# by spaces and tabs, that contain, respectively:
#   o The minute (0 through 59)
#   o The hour (0 through 23)
#   o The day of the month (1 through 31)
#   o The month of the year (1 through 12)
#   o The day of the week (0 through 6 for Sunday through Saturday)
#   o The shell command
# Each of these fields can contain the following:
#   o A number in the specified range
#   o Two numbers separated by a dash to indicate an inclusive range
#   o A list of numbers separated by commas
#   o An * (asterisk); meaning all allowed values
