+LONG_DESCRIPTION = """
+simplejson is a simple, fast, complete, correct and extensible
+JSON <http://json.org> encoder and decoder for Python 2.4+.  It is
+pure Python code with no dependencies, but includes an optional C
+extension for a serious speed boost.
+
+simplejson was formerly known as simple_json, but changed its name to
+comply with PEP 8 module naming guidelines.
+
+The encoder may be subclassed to provide serialization in any kind of
+situation, without any special support by the objects to be serialized
+(somewhat like pickle).
+
+The decoder can handle incoming JSON strings of any specified encoding
+(UTF-8 by default).
