+## 04_fix_442782_preprocessor_declaration_syntax.dpatch by Colin Watson <cjwatson@debian.org>.
+##
+## All lines beginning with `## DP:' are a description of the patch.
+## DP: Conventionally, preprocessor declarations should start with
+## DP:       '\"
+## DP:   rather than
+## DP:       .\"
+## DP:   Current man-db only supports the first (and recommended) syntax. So
+## DP:   Colin Watson provided this patch to fix docbook2x.
+## DP:
+## DP: <URL:http://bugs.debian.org/442782>
+## DP: <URL:http://lists.gnu.org/archive/html/groff/2007-11/msg00023.html>

+Edit by Bruno Victal <mirai@makinata.eu>:
