+      Serpent is one of the high-level programming languages used to
+      write Ethereum contracts. The language, as suggested by its name,
+      is designed to be very similar to Python; it is intended to be
+      maximally clean and simple, combining many of the efficiency
+      benefits of a low-level language with ease-of-use in programming
+      style, and at the same time adding special domain-specific
+      features for contract programming.
