+# This makefile deals with the manpages generated from POs with po4a, and
+# should be included in an automake Makefile.am.
+#
+# The po must be named:
+#   <man>.$(lang).po
+# If a man page require an addendum, you must name it:
+#   <man>.$(lang).po.addendum
+# Where <man> corresponds to a filename in the C directory (which contains
+# the English man pages).
+#
+# The POs suffix is $(lang).po to allow dl10n to detect the outdated POs.
+#
+#
+# If a man page cannot be generated (it is not sufficiently translated; the
+# threshold is 80%), it won't be distributed, and the build won't fail.
