   7 # Read seconds since the Epoch from stdin and create a plot with Bézier curve
   8 # showing how many timestamps there are per time period. Default period is one
   9 # week, but this can be changed on the command line. See ep_day(1) for command
  10 # line syntax.
  11 #
  12 # For example, to create a plot with commit activity per week in a Git
  13 # repository:
  14 #
  15 #   git log --format=%ct | act
  16 #
  17 # To create a plot from Apache logs showing daily visits:
  18 #
  19 #   access_log2epstat access.log | act -d 1
