1.1 misho 1: /-- This set of tests is not Perl-compatible. It checks on special features
2: of PCRE's API, error diagnostics, and the compiled code of some patterns.
3: It also checks the non-Perl syntax the PCRE supports (Python, .NET,
4: Oniguruma). Finally, there are some tests where PCRE and Perl differ,
5: either because PCRE can't be compatible, or there is a possible Perl
6: bug.
7:
8: NOTE: This is a non-UTF-8 set of tests. When UTF-8 is needed, use test
9: 5, and if Unicode Property Support is needed, use test 13. --/
10:
11: /-- Originally, the Perl >= 5.10 things were in here too, but now I have
12: separated many (most?) of them out into test 11. However, there may still
13: be some that were overlooked. --/
