+Blueprints support the errorhandler decorator just like the :class:`Flask`

------------------------------------
+`pip` and `setuptools` on Windows
+---------------------------------
+
+Sometimes getting the standard "Python packaging tools" like *pip*, *setuptools*
+and *virtualenv* can be a little trickier, but nothing very hard. The two crucial
+packages you will need are setuptools and pip - these will let you install
+anything else (like virtualenv). Fortunately there are two "bootstrap scripts"
+you can run to install either.
+
+If you don't currently have either, then `get-pip.py` will install both for you
+(you won't need to run ez_setup.py).
+
+`get-pip.py`_
 
-On Windows, installation of `easy_install` is a little bit trickier, but still
-quite easy.  The easiest way to do it is to download the
-`distribute_setup.py`_ file and run it.  The easiest way to run the file is to
-open your downloads folder and double-click on the file.
+To install the latest setuptools, you can use its bootstrap file:
 
-Next, add the `easy_install` command and other Python scripts to the
-command search path, by adding your Python installation's Scripts folder
-to the `PATH` environment variable.  To do that, right-click on the
-"Computer" icon on the Desktop or in the Start menu, and choose "Properties".
-Then click on "Advanced System settings" (in Windows XP, click on the
-"Advanced" tab instead).  Then click on the "Environment variables" button.
-Finally, double-click on the "Path" variable in the "System variables" section,
-and add the path of your Python interpreter's Scripts folder. Be sure to
-delimit it from existing values with a semicolon.  Assuming you are using
-Python 2.7 on the default path, add the following value::
+`ez_setup.py`_
 
+Either should be double-clickable once you download them. If you already have pip,
+you can upgrade them by running::
 
-    ;C:\Python27\Scripts
+    > pip install --upgrade pip setuptools
 
-And you are done!  To check that it worked, open the Command Prompt and execute
-``easy_install``.  If you have User Account Control enabled on Windows Vista or
-Windows 7, it should prompt you for administrator privileges.
+Most often, once you pull up a command prompt you want to be able to type ``pip``
+and ``python`` which will run those things, but this might not automatically happen
+on Windows, because it doesn't know where those executables are (give either a try!).
 
-Now that you have ``easy_install``, you can use it to install ``pip``::
+To fix this, you should be able to navigate to your Python install directory
+(e.g ``C:\Python27``), then go to ``Tools``, then ``Scripts``; then find the
+``win_add2path.py`` file and run that. Open a **new** Command Prompt and
+check that you can now just type ``python`` to bring up the interpreter.
 
-    > easy_install pip
+Finally, to install `virtualenv`_, you can simply run::
 
+    > pip install virtualenv
+    
+Then you can be off on your way following the installation instructions above.
