I’ve modified the sources to help you translating this excelent theme using Poedit.
If you want to traslate DeepBlue into your language, download .ZIP file and extract in a new directory.
Create an empty [your language].PO file. (as txt file)
Ie.: mine is called es_ES.PO
Then open the file with PoEdit, and use the option, update from POT file.
Select the file deepblue.pot.
Translate the strings, save and that’s all.
I really hope this helps you.
