+     "This is an easy-to-use implementation of ECDSA cryptography (Elliptic
+Curve Digital Signature Algorithm), implemented purely in Python.  With this
+library, you can quickly create keypairs (signing key and verifying key), sign
+messages, and verify the signatures.  The keys and signatures are very short,
+making them easy to handle and incorporate into other protocols.")
