+     "This package provides the timing functions @code{tic} and @code{toc} that
+can be nested.  One can record all timings while a complex script is running,
+and examine the values later.  It is also possible to instrument the timing call
+with custom callbacks.  In addition, this package provides class 'Stack',
+implemented as a vector, and class 'List', implemented as a list, both of whic
+support operations 'push', 'pop', 'first', 'last' and 'clear'.")
