 4) We also have the function ``get_package_info``, which inserts or updates package names and versions
    in the given metadata dictionary under the key "package_info".
    It stores the package information as {"package_info": {"package_name": "version_number"}}.
    This function can be used as follows. ::
 
-    from diffpy.utils.tools import get_user_info
+    from diffpy.utils.tools import get_package_info
     package_metadata = get_package_info("my_package")
 
    You can also specify an existing dictionary to be updated with the information. ::
