Usage:

        ./`basename $0` lang.po lang2.po ...

to update one or more <yourlang>.po files from the php files in
parent directory. The old .po file is save in a .po.old file.

When you e.g. want to update wpt-sr_RS.po, run ./`basename $0` wpt-sr_RS.po,
then edit wpt-sr_RS.po to update your translation.

After updating your translation, to compile wpt-sr_RS.po file use command:
msgfmt -o wpt-sr_RS.mo wpt-sr_RS.po
or replace sr_RS with locale for your language.
