// This 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.  Furthermore the literal
// letters in the data are encoded using ROT13 in a way that does not
// affect how the regexps match their input.  Finally the strings are
// scrambled to exercise the regexp engine on different input strings.
