+<p>Version 3 adds a new benchmark, <i>RegExp</i>.  The RegExp
+benchmark is generated by loading 50 of the most popular pages on the
+web and logging all regexp operations performed.  Each operation is
+given a weight that is calculated from an estimate of the popularity
+of the pages where it occurs and the number of times it is executed
+while loading each page.  Finally the literal letters in the data are
+encoded using ROT13 in a way that does not affect how the regexps
+match their input.
