Installation

To install eea.daviz into the global Python environment (or a workingenv), using a traditional Zope 2 instance, you can do this:

• When you're reading this you have probably already run easy_install eea.daviz. Find out how to install setuptools (and EasyInstall) here: http://peak.telecommunity.com/DevCenter/EasyInstall

• If you are using Zope 2.9 (not 2.10), get pythonproducts and install it via:

  python setup.py install --home /path/to/instance
  

  into your Zope instance.

• Create a file called eea.daviz-configure.zcml in the /path/to/instance/etc/package-includes directory. The file should only contain this:

  <include package="eea.daviz" />
  

Alternatively, if you are using zc.buildout and the plone.recipe.zope2instance recipe to manage your project, you can do this:

• Add eea.daviz to the list of eggs to install, e.g.:

  [buildout]
  eggs = eea.daviz
  

• Tell the plone.recipe.zope2instance recipe to install a ZCML slug:

  [instance]
  recipe = plone.recipe.zope2instance
  zcml = eea.daviz
  

• Re-run buildout, e.g. with:

  $ ./bin/buildout
  

You can skip the ZCML slug if you are going to explicitly include the package from another package's configure.zcml file.
