+/**
+ * These shim entries allow us to make old XPIDL interfaces implementing DOM
+ * APIs as non-scriptable in order to save some runtime memory on Firefox OS,
+ * without breaking the entries under Components.interfaces which might both
+ * be used by our code and add-ons. Specifically, the shim entries provide
+ * the following:
+ *
+ * * Components.interfaces.nsIFoo entries. These entries basically work
+ * almost exactly as the usual ones that you would get through the
+ * XPIDL machinery. Specifically, they have the right name, they reflect
+ * the right IID, and they will work properly when passed to QueryInterface.
+ *
+ * * Components.interfaces.nsIFoo.CONSTANT values. These entries will have
+ * the right name and the right value for most integer types. Note that
+ * support for non-numerical constants is untested and will probably not
+ * work out of the box.
+ *
+ * FAQ:
+ * * When should I add an entry to the list here?
+ * Only if you're making an XPIDL interfaces which has a corresponding
+ * WebIDL interface non-scriptable.
+ * * When should I remove an entry from this list?
+ * If you are completely removing an XPIDL interface from the code base. If
+ * you forget to do so, the compiler will remind you.
+ * * How should I add an entry to the list here?
+ * First, make sure that the XPIDL interface in question is non-scriptable
+ * and also has a corresponding WebIDL interface. Then, add two include
+ * entries above, one for the XPIDL interface and one for the WebIDL
+ * interface, and add a shim entry below. If the name of the XPIDL
+ * interface only has an "nsIDOM" prefix prepended to the WebIDL name, you
+ * can use the DEFINE_SHIM macro and pass in the name of the WebIDL
+ * interface. Otherwise, use DEFINE_SHIM_WITH_CUSTOM_INTERFACE.

+- DOCS
+- improve error handling
+ - should some errors really be warnings?
+ - should autoreg support additional channel to receive warnings so that
+ an installer can decide whether or not to accept the consequences of
+ leaving the newly installed files in place?
+- verification of interfaces (warnings and/or errors)
+ - verify that repeated interfaces are identical in all ways
+ - verify that interface names are always one-to-one with iids
+- check for truncated xpt files and version problems
+ - http://bugzilla.mozilla.org/show_bug.cgi?id=33193
+- TESTS!
+ - e.g. verify the merge stuff really works for various inputs.
+ - we really need a set of .xpt and .zip files and code that does an array
+ of autoreg and interfaceinof use activitities to test various corners
+ of the system.
+- better autoreg logging
+- use only 32 bits for file size?
