# This script creates the translated docbook files by inserting the translated po text into the original 
# english docbook files in the language folder ../doc/i18n/$lang
# with po2xml *.docbook.po > *.docbook
# Before running this script the according english docbook files need to be copied in the language folder ../doc/i18n/$lang
# for a 100% merge the po and the english docbook files need to have the same date
# The created docbook files needs to be copied into the proper language dir ../doc/$lang


# Requirements: bash, po2xml
# usage:  run ./update_docbook ru Russian

# test if $2 is used
if test $# -eq 0 || test "$2" = "" ; then
  echo "update_docbook <lang_subdir> <language>"
  exit
fi

# read first parameter

    # po2xml index_en.docbook index_ru_new.docbook.po > index_ru.docbook
    po2xml ${FILENAME} $FILENAME.po > ${FILENAME}.new
    # rename docbook.new into docbook
