# Using polib.py from https://bitbucket.org/izi/polib/wiki/Home

# Usage : python2 mergePo.py qt.po gtk.po
# Find in the first argument po file the translated lines of the gtk po file
# (if existing) and replace the translation for the po file.
# For those not found, no translation is provided.

# something like: python2 mergePo.py gcompris_fi.po fi.po && sed '/^#|/ d' < gcompris_fi.po > qtgl.po && mv qtgl.po gcompris_fi.po
