## 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.
