+     "@code{info-rename-buffer-mode} is a global minor-mode that automatically
+renames Info buffers to match their visiting manual.  That's a useful feature
+when consulting several Info manuals simultaneously, because it frees the user
+from the burden of renaming Info buffers to descriptive names manually before
+visiting another manual, thus avoiding accidentally overriding the currently
+visited node in case the user tries to open a new Info buffer.")
