+# Automake fragment to distribute and install gettext .po/.mo files, intended
+# for use in a non-recursive build setup.  This does not include rules to
+# generate the .pot file.  Two variables must be defined:
+#
+#   POFILES: the complete list of .po files included with the package, and
+#   MOFILES: the set of .mo files to be installed (a user-selected subset
+#            of the available options).
+#
+# One way to define these variables is to use the DX_LINGUAS autoconf macro
+# which normally accompanies this fragment.
