 Direct `Component` sub-classes also do not need to worry about invoking the base classes `__init__` method (which is empty).

+=== Components instantiating other Components ===
+
+If one `Component` instantiates another, it typically will use the same `ComponentManager`, instead of creating a new `ComponentManager`.
+
+{{{
+#!python
+    class MyComponent(Component):
+        def callOtherComponent(self):
+            MyOtherComponent(self.compmgr).someFunction()
+}}}
+
+Note that within trac, the component manager is more commonly referenced as `self.env`.
