+
+The test data has been edited to reflect RE2/Go differences:
+  * In a star of a possibly empty match like (a*)* matching x,
+    the no match case runs the starred subexpression zero times,
+    not once.  This is consistent with (a*)* matching a, which
+    runs the starred subexpression one time, not twice.
+  * The submatch choice is first match, not the POSIX rule.
+
+Such changes are marked with 'RE2/Go'.

+RE2 Test Files
+
+re2-exhaustive.txt.bz2 and re2-search.txt are built by running
+'make log' in the RE2 distribution https://github.com/google/re2/
+
+The exhaustive file is compressed because it is huge.
