+ * Since regular expressions have been part of JavaScript since 1.2, there
+ * are already tests for regular expressions in the js1_2/regexp folder.
+ *
+ * These new tests try to supplement the existing tests, and verify that
+ * our implementation of RegExp conforms to the ECMA specification, but
+ * does not try to be as exhaustive as in previous tests.
+ *
+ * The [,limit] argument to String.split is new, and not covered in any
+ * existing tests.
+ *
+ * String.split cases are covered in ecma/String/15.5.4.8-*.js.
+ * String.split where separator is a RegExp are in
+ * js1_2/regexp/string_split.js
