-     * https://googleplex-android-review.git.corp.google.com/#/c/433061
-     *
-     * More details about http://b/13216167:
-     *   PackageManager may fail to update shared library.
-     *
-     * Native library directory in an updated package is a symbolic link
-     * to a directory in /data/app-lib/<package name>, for example:
-     * /data/data/com.android.chrome/lib -> /data/app-lib/com.android.chrome[-1].
-     * When updating the application, the PackageManager create a new directory,
-     * e.g., /data/app-lib/com.android.chrome-2, and remove the old symlink and
-     * recreate one to the new directory. However, on some devices (e.g. Sony Xperia),
-     * the symlink was updated, but fails to extract new native libraries from
-     * the new apk.
-     *
-     * We make the following changes to alleviate the issue:
-     *  1) name the native library with apk version code, e.g.,
-     *     libchrome.1750.136.so, 1750.136 is Chrome version number;
-     *  2) first try to load the library using System.loadLibrary,
-     *     if that failed due to the library file was not found,
-     *     search the named library in a /data/data/com.android.chrome/app_lib
-     *     directory. Because of change 1), each version has a different native
-     *     library name, so avoid mistakenly using the old native library.
-     *
-     *  If named library is not in /data/data/com.android.chrome/app_lib directory,
-     *  extract native libraries from apk and cache in the directory.
-     *
-     * This function doesn't throw UnsatisfiedLinkError, the caller needs to
-     * check the return value.

-$$ This is a pump file for generating file templates.  Pump is a python
-$$ script that is part of the Google Test suite of utilities.  Description
-$$ can be found here:
-$$
-$$ http://code.google.com/p/googletest/wiki/PumpManual
-$$
-
-$$
-$$ MAX_ARITY controls the number of arguments that Bind() supports.
-$$ The amount of code, and more importantly, the number of template types
-$$ generated by pump grows at O(MAX_ARITY^2).
-$$
-$$ We tried going to 11 and found it imposed an extra 10 penalty on windows
-$$ cycle times compared to our original baseline of 6.
-$$
-$$ Currently 7 is chosen as a compromise between supporting a convenient
-$$ number of arguments and keeping compile times low.  At 7, we have 115
-$$ templates being generated by pump.
-$$
-$$ Be careful when adjusting this number.  If people find a need to bind
-$$ a larger number of arguments, consider refactoring the function to use
-$$ a param struct instead of raising the MAX_ARITY.
-$$
-$$ See http://crbug.com/98542 for more context.

-// RETURN TYPES
-//
-// Though Bind()'s result is meant to be stored in a Callback<> type, it
-// cannot actually return the exact type without requiring a large amount
-// of extra template specializations. The problem is that in order to
-// discern the correct specialization of Callback<>, Bind would need to
-// unwrap the function signature to determine the signature's arity, and
-// whether or not it is a method.
-//
-// Each unique combination of (arity, function_type, num_prebound) where
-// function_type is one of {function, method, const_method} would require
-// one specialization.  We eventually have to do a similar number of
-// specializations anyways in the implementation (see the Invoker<>,
-// classes).  However, it is avoidable in Bind if we return the result
-// via an indirection like we do below.
-//
-// TODO(ajwong): We might be able to avoid this now, but need to test.
-//
-// It is possible to move most of the COMPILE_ASSERT asserts into BindState<>,
-// but it feels a little nicer to have the asserts here so people do not
-// need to crack open bind_internal.h.  On the other hand, it makes Bind()
-// harder to read.
