+# $(srcdir)/$(DOMAIN).pot is only created when needed. When xgettext finds no
+# internationalized messages, no $(srcdir)/$(DOMAIN).pot is created (because

+# checks out the package via CVS, and the $(DOMAIN).pot file is not in CVS,
+# "make" will update the $(DOMAIN).pot and the $(CATALOGS), but subsequent
+# invocations of "make" will do nothing. This timestamp would not be necessary
+# if updating the $(CATALOGS) would always touch them; however, the rule for
+# $(POFILES) has been designed to not touch files that don't need to be
+# changed.
