+/-- This set of tests is not Perl-compatible. It checks on special features
+ of PCRE's API, error diagnostics, and the compiled code of some patterns.
+ It also checks the non-Perl syntax the PCRE supports (Python, .NET,
+ Oniguruma). Finally, there are some tests where PCRE and Perl differ,
+ either because PCRE can't be compatible, or there is a possible Perl
+ bug.
+
+ NOTE: This is a non-UTF set of tests. When UTF support is needed, use
+ test 5, and if Unicode Property Support is needed, use test 7. --/
