The r21presentation plugin provides an R2.1 style look and feel for Eclipse. This look and feel is accomplished entirely through the Presentations API, no changes are needed to the base eclipse release. Use: 1. Ensure the plugin is installed (look in your eclipse/plugins directory for org.eclipse.ui.presentations.r21_3.0.0). 2. Add the contents of the r21presentation.ini file to your primary plugin's "plugin_customization.ini" file. In the basic Eclipse IDE, this file is located in plugins/org.eclipse.platform_3.0.0. 3. Resolve any conflicts in the plugin_customization.ini file to favour the settings for this project. E.g., DOCK_PERSPECTIVE_BAR is set to "topRight" in the basic platform but should be "left" for the R21 presentation.
