+Package Relative Imports
+========================
+
+Relative imports use leading dots. A single leading dot indicates a relative
+import, starting with the current package. Two or more leading dots indicate a
+relative import to the parent(s) of the current package, one level per dot
+after the first. For example, given the following package layout::
+
+    package/
+        __init__.py
+        subpackage1/
+            __init__.py
+            moduleX.py
+            moduleY.py
+        subpackage2/
+            __init__.py
+            moduleZ.py
+        moduleA.py
+
+In either ``subpackage1/moduleX.py`` or ``subpackage1/__init__.py``,
+the following are valid relative imports::
+
+    from .moduleY import spam
+    from .moduleY import spam as ham
+    from . import moduleY
+    from ..subpackage1 import moduleY
+    from ..subpackage2.moduleZ import eggs
+    from ..moduleA import foo
+
+Absolute imports may use either the ``import <>`` or ``from <> import <>``
+syntax, but relative imports may only use the second form; the reason
+for this is that::
+
+    import XXX.YYY.ZZZ
+
+should expose ``XXX.YYY.ZZZ`` as a usable expression, but .moduleY is
+not a valid expression.
