+This is a file of miscellaneous text that is used as test data for checking
+that the pcregrep command is working correctly. The file must be more than 24K
+long so that it needs more than a single read() call to process it. New
+features should be added at the end, because some of the tests involve the
+output of line numbers, and we don't want these to change.
+
+PATTERN at the start of a line.
+In the middle of a line, PATTERN appears.
+
+This pattern is in lower case.
+
+Here follows a whole lot of stuff that makes the file over 24K long.

+/-- This is a specialized test for checking, when PCRE is compiled with the
+EBCDIC option but in an ASCII environment, that newline and white space
+functionality is working. It catches cases where explicit values such as 0x0a
+have been used instead of names like CHAR_LF. Needless to say, it is not a
+genuine EBCDIC test! In patterns, alphabetic characters that follow a backslash
+must be in EBCDIC code. In data, newlines and other spacing characters must be
+in EBCDIC, but can be specified as escapes. --/

+/-- 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. --/

+functionality is working. It catches cases where explicit values such as 0x0a
+have been used instead of names like CHAR_LF. Needless to say, it is not a
+genuine EBCDIC test! In patterns, alphabetic characters that follow a backslash
