# You must set the $(lang) variable when you include this makefile.
#
# You can use the $(po4a_translate_options) variable to specify additional
# options to po4a.
# For example: po4a_translate_options=-L KOI8-R -A KOI8-R
#
#
# This makefile deals with the manpages generated from POs with po4a, and
# should be included in an automake Makefile.am.
#
# The po must be named:
#   <man>.$(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# The POs suffix is $(lang).po to allow dl10n to detect the outdated POs.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.
