Languages
A language contains a set of keys as well as the strings which those keys represent.
For each language, the keys will remain the same, but the strings will change.
To add new languages to the Resource Bundle Editor, select "Add language..." from the Edit menu.
A dialog appears asking for the Language and Country of your new Language. The country code is optional.
If you don't know the ISO codes for a particular language or country, press the arrow buttons beside each of the
boxes to select from a list.
Once selected a new column is added to the Resource Bundle Editor, where you may enter the appropriate strings.
