Open-Falcon support zh_CN by default. Any translation will be appreciated.

If you want to translate open-falcon to a new language or just refine the exist translation, you could follow the instructions below.

## refine the exist translation

1. find what you want to translate in the source code and replace it to `{{_('xxx')}}`.
2. run `python ./scripts/tr_update.py`, it will update `rrd/translations/foo/LC_MESSAGES/messages.po`.
3. run `python ./scripts/tr_compile.py`, it will generate a complied file in `rrd/translations/foo/LC_MESSAGES/messages.mo`


## create a new language(such as Spanish support)
1. update `rrd/config.py`, add a new key to `LANGUAGES`, such as:
    
        LANGUAGES   = {
            'en':  'English',
            'zh_CN':  'Chinese-Simplified',
            'es': Spanish,
        }
    
2. run `python ./scripts/tr_init.py`, it will update `rrd/translations/es/LC_MESSAGES/messages.po`.
3. find what you want to translate in the source code and replace it to `{{_('xxx')}}`.
4. run `python ./scripts/tr_update.py`, it will update `rrd/translations/es/LC_MESSAGES/messages.po`.
5. run `python ./scripts/tr_compile.py`, it will generate a complied file in `rrd/translations/es/LC_MESSAGES/messages.mo`
