+; this file contains a script of tests to run through regress.exe
+;
+; comments start with a semicolon and proceed to the end of the line
+;
+; changes to regular expression compile flags start with a "-" as the first
+; non-whitespace character and consist of a list of the printable names
+; of the flags, for example "match_default"
+;
+; Other lines contain a test to perform using the current flag status
+; the first token contains the expression to compile, the second the string
+; to match it against. If the second string is "!" then the expression should
+; not compile, that is the first string is an invalid regular expression.
+; This is then followed by a list of integers that specify what should match,
+; each pair represents the starting and ending positions of a subexpression
+; starting with the zeroth subexpression (the whole match).
+; A value of -1 indicates that the subexpression should not take part in the
+; match at all, if the first value is -1 then no part of the expression should
+; match the string.
+;
+; Tests taken from BOOST testsuite and adapted to glibc regex.

+# PCRE LICENCE
+# ------------
+#
+# PCRE is a library of functions to support regular expressions whose syntax
+# and semantics are as close as possible to those of the Perl 5 language.
