Step 2: Fetching the Wiki Application from SVN
The next step in installing a new Zope package is to get the package. You generally just download a TAR or ZIP archive and unpack it in the directory. However, for the Wiki application, there is no archive, and you have to fetch the package from SVN.
If you have the SVN client installed on your computer, you can use the following command to do an anonymous checkout of the wiki package from the Zope X3 3.0 branch:
svn co svn://svn.zope.org/repos/main/Zope3/branches/ZopeX3-3.0/src/zwiki zwiki
Although SVN allows you to name the created directory any way you want to, it is necessary to name the directory zwiki because imports in the package assume this name. When the command line returns, the package should be located at Zope3-Instance/lib/python//zwiki.
