README.md

You have a translation file full of English. You want to translate it to French easily.

1. Output all translation strings

python easy_i18n.py en.json output

2. Copy those strings into Google Translate

3. Copy the output of Google Translate into a file

Let's call the file translated.txt

python easy_i18n.py en.json merge translated.txt > 

It outputs the fr.json file.

Check the output well since the tool is very simple and may have errors.
