-<B>OVERVIEW</B>
-  Google Cloud Storage provides a cyclic redundancy check (CRC) header that
-  allows clients to verify the integrity of object contents. For non-composite
-  objects GCS also provides an MD5 header to allow clients to verify object
-  integrity, but for composite objects only the CRC is available. gsutil
-  automatically performs integrity checks on all uploads and downloads.
-  Additionally, you can use the "gsutil hash" command to calculate a CRC for
-  any local file.
-
-  The CRC variant used by Google Cloud Storage is called CRC32C (Castagnoli),
-  which is not available in the standard Python distribution. The implementation
-  of CRC32C used by gsutil is provided by a third-party Python module called
-  `crcmod <https://pypi.python.org/pypi/crcmod>`_.
-
-  The crcmod module contains a pure-Python implementation of CRC32C, but using
-  it results in very poor performance. A Python C extension is also provided by
-  crcmod, which requires compiling into a binary module for use. gsutil ships
-  with a precompiled crcmod C extension for Mac OS X; for other platforms, see
-  the installation instructions below.
-
-  At the end of each copy operation, the gsutil cp and rsync commands validate
-  that the checksum of the source file/object matches the checksum of the
-  destination file/object. If the checksums do not match, gsutil will delete
-  the invalid copy and print a warning message. This very rarely happens, but
-  if it does, please contact gs-team@google.com.
-
-
-<B>CONFIGURATION</B>
-  To determine if the compiled version of crcmod is available in your Python
-  environment, you can inspect the output of the gsutil version command for the
-  "compiled crcmod" entry::
-
-    $ gsutil version -l
-    ...
-    compiled crcmod: True
-    ...
-
-  If your crcmod library is compiled to a native binary, this value will be
-  True. If using the pure-Python version, the value will be False.
-
-  To control gsutil's behavior in response to crcmod's status, you can set the
-  "check_hashes" configuration variable. For details on this variable, see the
-  surrounding comments in your gsutil configuration file. If check_hashes is not
-  present in your configuration file, rerun gsutil config to regenerate the
-  file.

-<B>INSTALLATION</B>
-  CentOS, RHEL, and Fedora
-  ------------------------
-
-  To compile and install crcmod:
-
-    sudo yum install gcc python-devel python-setuptools
-    sudo easy_install -U pip
-    sudo pip uninstall crcmod
-    sudo pip install -U crcmod
-
-  Debian and Ubuntu
-  -----------------
-
-  To compile and install crcmod:
-
-    sudo apt-get install gcc python-dev python-setuptools
-    sudo easy_install -U pip
-    sudo pip uninstall crcmod
-    sudo pip install -U crcmod
-
-  Mac OS X
-  --------
-
-  gsutil distributes a pre-compiled version of crcmod for OS X, so you shouldn't
-  need to compile and install it yourself. If for some reason the pre-compiled
-  version is not being detected, please let the Google Cloud Storage team know
-  (see "gsutil help support").
-
-  To compile manually on OS X, you will first need to install
-  `XCode <https://developer.apple.com/xcode/>`_ and then run:
-
-    sudo easy_install -U pip
-    sudo pip install -U crcmod
-
-  Windows
-  -------
-
-  An installer is available for the compiled version of crcmod from the Python
-  Package Index (PyPi) at the following URL:
-
-  https://pypi.python.org/pypi/crcmod/1.7
-
-  MSI installers are available for the 32-bit versions of Python 2.6 and 2.7.
