+# The tests are in a separate file 't/op/re_tests'.
+# Each line in that file is a separate test.
+# There are five columns, separated by tabs.
+#
+# Column 1 contains the pattern, optionally enclosed in C<''>.
+# Modifiers can be put after the closing C<'>.
+#
+# Column 2 contains the string to be matched.
+#
+# Column 3 contains the expected result:
+# y expect a match
+# n expect no match
+# c expect an error
+#
+# Columns 4 and 5 are used only if column 3 contains C<y> or C<c>.
+#
+# Column 4 contains a string, usually C<$&>.
+#
+# Column 5 contains the expected result of double-quote
+# interpolating that string after the match.
