# COMMON MISTAKES
# - A white ending line is required, otherwise last command will not be executed
# - % character in a command must be escaped [ echo `date +\%Y\%m\%d` ]
# - % character not escaped means a new line
# - 'day' and 'week day' fields are evaluated with a OR operation:
#    day=1 weekday=mon  ==  'execute command if now is 1st of the month OR is Monday'
