+"""A Python driver for PostgreSQL
+
+psycopg is a PostgreSQL_ database adapter for the Python_ programming
+language. This is version 2, a complete rewrite of the original code to
+provide new-style classes for connection and cursor objects and other sweet
+candies. Like the original, psycopg 2 was written with the aim of being very
+small and fast, and stable as a rock.
