+be viewed with Adobe Reader in place of marginal texts.  Small icons indicate
+the in-text position where the message originates, popups provide the messages
+themselves.  Thus bugfixes and other such communications are clearly visible
+together when viewing the document, while the document itself is not
+obscured.")
