+    texi2txt: Use ChangeLog date instead of build date
+    
+    in order to make builds reproducible.
+    See https://reproducible-builds.org/ for why this is good.
+    
+    This date call works with GNU date and BSD date.
+    
+    Without this patch, /usr/share/doc/packages/WindowMaker/README.i18n
+    will differ in the line
+      Published by The Window Maker team on ...
+    
+    ---
+    An alternative solution could use the $SOURCE_DATE_EPOCH variable
+    defined in https://reproducible-builds.org/specs/source-date-epoch/
