+# If your project uses "gettextize --intl" to put a source-code
+# copy of libintl into the package, every Makefile.am needs
+# -I$(top_builddir)/intl, so that <libintl.h> can be found in this directory.
+# Here's one way to do this:
+#AM_CPPFLAGS += -I$(top_builddir)/intl
+# This option has no effect when the user disables NLS (because then
+# the intl directory contains no libintl.h file). This option is not
+# enabled by default because the intl directory might not exist if
+# your project does not use "gettext --intl", and some compilers
+# complain about -I options applied to nonexistent directories.
