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/instanceinto 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.davizTell the plone.recipe.zope2instance recipe to install a ZCML slug:
[instance] recipe = plone.recipe.zope2instance zcml = eea.davizRe-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.
