+     "Correctly sizing delimiters is very difficult, particularly in
+well-architected documents: a correctly engineered mathematical document will
+include macros for all operations, and these macros necessarily will include
+delimiters (such as parentheses).  However, the correct size for the delimiter
+cannot be chosen ahead of time, because it will depend on the arguments; two
+options are available: Provide optional arguments to each notation macro for
+choosing delimiter sizes.  This is nearly intractable to do in practice.
+Ignore delimiter sizes.  With @code{jmsdelim} we offer an alternative: the
+correct delimiter sizes can be set at the leaf nodes of a mathematical
+expression, and magically bubble upward through the delimiters.")
