+// containing the special file "__init__.py" that is executed when a Python
+// script executes the statement "import M".

+// Inside __init__.py we add an import statement for Foo_ice, causing

+// Of course, another Slice file Bar.ice may contain definitions for the

+// to contain an additional import statement for Bar_ice. Therefore a
+// Python script executing "import M" implicitly imports the definitions
+// from both Foo_ice and Bar_ice.

-// For each Slice file Foo.ice we generate Foo_ice.py containing the Python
-// mappings. Furthermore, for each Slice module M in Foo.ice, we create a
-// Python package of the same name. This package is simply a subdirectory
-// containing the special file "__init__.py" that is executed when a Python
-// script executes the statement "import M".
-//
-// Inside __init__.py we add an import statement for Foo_ice, causing
-// Foo_ice to be imported implicitly when M is imported.
-//
-// Of course, another Slice file Bar.ice may contain definitions for the
-// same Slice module M, in which case the __init__.py file for M is modified
-// to contain an additional import statement for Bar_ice. Therefore a
-// Python script executing "import M" implicitly imports the definitions
-// from both Foo_ice and Bar_ice.
-//
-// The __init__.py file also contains import statements for submodules,
-// so that importing the top-level module automatically imports all of
-// its submodules.
-//
-// The PackageVisitor class creates the directory hierarchy to mirror the
-// Slice module hierarchy, and updates the __init__.py files as necessary.
