sqlite3 top-level variables, such as version, sqlite_version, version_info, and sqlite_version_info are all useful for Python users of the module -- even essential at times. Yet there is no mention of them in the Py 2.7.3 documentation. 

dir(sqlite3) reveals a longer list. It would be good if someone with a deeper knowledge of the module could assemble a list of useful items and add them to the sqlite3 documentation.
