# this script symlinks all cbx po files to a language directory structure, as 
# it is used by the pootle translation server
#
# all language files are chgrp'ed to the 'pootle' group and group write
# permissions are added
#
# call this script whenever you add _new_ languages to your translation server
#
# it is useful to be root while calling it - otherwise chgrp will fail
