This is small note about 'translator.pl'.
Author: Pawel Skuza
email: pawelzc@cz.top.pl

Script 'translator.pl' do two things:
1. Prepare strings which can be translate;
2. Translate strings used gettext.

1. Prepare strings which can be translate.
Copy file 'translator.pl' into root koha directory and execute it.
eg. 
    cd /usr/src/koha
    cp scripts/translator.pl .
    ./translator.pl some_file_name
    xgettext some_file_name -okoha.po
    vi koha.po 					//now you must translate koha.po
    msgfmt koha.po -okoha.mo
    cp koha.mo /usr/share/locale/$$/LC_MESSAGES //where $$ is your language

note: if you omnit 'some_file_name' translator create 'koha.gettext.c'

2. Translate strings used gettext.
You have to configure your apache. Put this lines in koha and opac virtual:

    Action text/html /cgi-bin/koha/translator.pl
    Action text/plane /cgi-bin/koha/translator.pl

Don't forget set up the language preference in your browser.
