+# Generates sparklines for a set of data.
+#
+# Here's a good web-based sparkline generator that was a bit of inspiration
+# for spark:
+#
+#   https://datacollective.org/sparkblocks
+#
+# spark takes a comma-separated or space-separated list of data and then prints
+# a sparkline out of it.
+#
+# Examples:
+#
+#   spark 1 5 22 13 53
+#   # => ▁▁▃▂▇
+#
+#   spark 0 30 55 80 33 150
+#   # => ▁▂▃▅▂▇
+#
+#   spark -h
+#   # => Prints the spark help text.
+
+# Generates sparklines.
+#
+# $1 - The data we'd like to graph.
