    Wait a few seconds until the content of the selected update site is displayed under the combo-box.
    Expand the Collaboration group and select the Subversive features that you would like to install. Certain Subversive features are required if you want to work with SVN, others are optional and offer some additional functionality. You can skip the optional features, if you wish.
    Follow the next steps to install the selected Subversive features using the standard plug-in installation procedure. Reboot Eclipse after installation is complete.
