#!/bin/bash
# This script will synchronize language file with the master 
# english translation using diff(1) utility.
# It doesn't translate strings, only inserts english versions
# to proper positions and deletes removed. And it doesn't 
# synchronize commented lines. 
# You need to have GNU ed and diff installed in $PATH.
# 
# Usage: synch <language>
#
#   <language> is the filename without the .php extension
#
# BTW, diff should create better ed scripts than previous 
# version of synch (that one with awk code). If it will not, 
# be frightened about patching Linux kernel sources ;-)
