# Line 1  Line 1 
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    /-- Originally, the Perl >= 5.10 things were in here too, but now I have
9        separated many (most?) of them out into test 11. However, there may still
10        be some that were overlooked. --/
