# you may set following variables
# SRCDIR root of the documentation repository
# PODIR place where to create the po
# PUB_DIR place where to publish localized files

# USER-CONFIGURABLE VARIABLES

# This value is used to compare with the output of pocount
# 0 means we do not want any non-translated string, i. e. if there is even just 1 untranslated string, output will be 100% English
