#
# Create an ascii representation of a timeline, given the number of days
# between each event.
#
# You can take a screenshot of the ascii timeline and then scale it to any
# width, quickly giving you an accurate representation of spacing between
# events so you can create a graphical timeline using circles and lines (or
# whatever).

# USAGE: ./timeline-ascii.py days1 days2 ... daysN
