-This file describes how to setup Eclipse and then the Python Charts project
-
-Setup Eclipse
--------------
-These instructions were tested on Linux, but are very similar for Windows and
-Mac.
-1. Ensure you have Python 2.x installed
-2. Download and install Google App Engine SDK for Python from 
-   http://code.google.com/appengine/downloads.html
-3. Note which location you put App Engine in, as this will be needed later on.
-4. Download Eclipse from http://www.eclipse.org. Any distribution will probably
-   do, but if you're going to do mainly web development, you might pick Eclipse
-   IDE for JavaScript Web Developers
-5. Install the PyDev plugin using the Eclipse update site mentioned at 
-   http://pydev.org/download.html
-6. Install the Google Plugin for Eclipse: http://code.google.com/eclipse/
-
-Setup the project
------------------
-Generic instructions are available at
-http://code.google.com/appengine/docs/python/gettingstarted/ but the following
-should be enough:
-1. Launch Eclipse and create a workspace
-2. Create a new PyDev Project
-3. In the PyDev Project wizard, uncheck the "Use Default" checkbox for Project
-   contents and browse to your tools/python_charts directory.
-4. Enter a project name. We'll assume PythonCharts in the examples below.
-5. In the radio button of the lower part of the window, select
-   "Add project directory to the PYTHONPATH"
-6. Click Finish
-7. Select the Run > Run Configuration… menu item
-8. Create a new "Python Run" configuration
-9. Select your Python Charts project as project
-10. As Main Module, enter the path to your dev_appserver.py, which is a part
-    of your App Engine installation,
-    e.g. /usr/local/google_appengine/dev_appserver.py
-11. At the Arguments tab, enter the location of your project root.
-    Using Eclipse variables if your project name is PythonCharts:
-    ${workspace_loc:PythonCharts}
-12. Launch the development app server by clicking the Run button.
-13. Launch a browser and go to http://localhost:8080
