+	help
+	  docopt helps you create most beautiful command-line
+	  interfaces easily.  The option parser is generated based on
+	  the beautiful help message that you write yourself. This way
+	  you don't need to write this stupid repeatable parser-code,
+	  and instead can write only the help message-- the way you
+	  want it.
