+
+# The 'rake/clean' file defines two file lists (CLEAN and CLOBBER) and
+# two rake tasks (:clean and :clobber).
+#
+# [:clean] Clean up the project by deleting scratch files and backup
+#          files.  Add files to the CLEAN file list to have the :clean
+#          target handle them.
+#
+# [:clobber] Clobber all generated and non-source files in a project.
+#            The task depends on :clean, so all the clean files will
+#            be deleted as well as files in the CLOBBER file list.
+#            The intent of this task is to return a project to its
+#            pristine, just unpacked state.
