# break\_interval
This simple program plays a jingle at a specified interval in minutes. It is
meant to be used as a way to notify the user to take a break when the interval
jingle plays.
# For usage:
./break_interval --help
Running the program with no args will default to playing a jingle every 5
minutes.
