+    IBM Rational ClearCase is a version control, workspace management, parallel
+    development support, and build automation solution developed by IBM. The
+    ClearCase client plugin is an experimental plugin that you can enable by
+    selecting \gui Help > \gui {About Plugins} > \gui {Version Control} >
+    \gui ClearCase. The ClearCase client plugin is available on Linux and
+    Windows for accessing a ClearCase server.
