+#  correct_escapes: use correct backslash escaping
+#
+#  Prior to version 3.0.5, the handling of backslashes was a little
+#  awkward, i.e. "wrong".  In some cases, to get one backslash into
+#  a regex, you had to put 4 in the config files.
+#
+#  Version 3.0.5 fixes that.  However, for backwards compatibility,
+#  the new method of escaping is DISABLED BY DEFAULT.  This means
+#  that upgrading to 3.0.5 won't break your configuration.
+#
+#  If you don't have double backslashes (i.e. \\) in your configuration,
+#  this won't matter to you.  If you do have them, fix that to use only
+#  one backslash, and then set "correct_escapes = true".
+#
+#  You can check for this by doing:
+#
+#  $ grep '\\\\' $(find raddb -type f -print)
+#
