+This directory contains Python code Google is releasing as open source,
+to demonstrate the Google Storage API and to provide a command line
+tool for manipulating data in the system.
+
+Contents:
+  - gsutil is the command line tool
+  - cloudreader contains an example Google App Engine app that accesses Google
+    storage
+  - both depend on the boto open source Python library, version 2.0b4 or
+    later.  The boto repository is mapped into the gsutil svn tree using an
+    svn:externals propset and is distributed with the gsutil tar ball.
+
+The cloudreader app is explained in cloudreader/README.google.
+
+Prerequisites:
+
+Gsutil requires either
+ - Python 2.6 or later, or
+ - Python 2.5 or later, with the 'simplejson' library installed.
+
+To install gsutil take the following steps:
+
+1. Pick a place where you want to install the software.  You can
+   install the code wherever you prefer; for brevity the instructions below
+   assume you want to install in $HOME/gsutil.
+
+2. To install gsutil on Linux/Unix or MacOS, open a shell window, change
+   directories to where you downloaded the gsutil.tar.gz file, and do this:
+   % tar xfz gsutil.tar.gz -C $HOME
+
+   Then add the following line to your $HOME/.bashrc shell initialization
+   file:
+       export PATH=${PATH}:$HOME/gsutil
+
+   The next time you start a shell you should be able to run gsutil from
+   the command line.
+
+3. To install gsutil on Windows, install cygwin (http://www.cygwin.com/),
+   with at least version 2.6.5 of Python. Once you have that, start a shell
+   and follow the Linux instructions above for unpacking and installing gsutil.
+
+4. The first time you try to run gsutil, it will detect that you have no
+   configuration file containing your credentials, interactively prompt you,
+   and create the file.  
+
+   After this you can use the tool.  Running gsutil with with no arguments
+   will print a help summary.
+
+For more information on installing and using gsutil, see
