-# Usage: make_ib_classes.py output.mm input.xib [...]
-#
-# Generates an Objective-C++ file at output.mm referencing each class described
-# in input.xib.
-#
-# This script is useful when building an application containing .nib or .xib
-# files that reference Objective-C classes that may not be referenced by other
-# code in the application.  The intended use case is when the .nib and .xib
-# files refer to classes that are built into a static library that gets linked
-# into the main executable.  If nothing in the main executable references those
-# classes, the linker will not include them in its output (without -all_load or
-# -ObjC).  Using this script, references to such classes are created, such that
-# if output.mm is compiled into the application itself, it will provide the
-# class references and cause the linker to bring the required code into the
-# executable.
-#
-# If your application is structured in the above way, and you're plagued with
-# messages like:
-#   app[12345:101] Unknown class `MyApp' in nib file, using `NSObject' instead.
-# then this script may be right for you.
