Translations for parts of the frontend must be handled via Module translations.
Translations for the core system and the setup process are handled with .po and .mo files.
Although the .po file can be edited manually, contributors are highly advised to generate this files automatically. This can be done in three steps with the command line.
These files generate two files: potfiles.txt and contenido.pot. Both files must be updated in the version control. With the .pot file the language catalog of each languages .po file can be refreshed and translated. This can be done with the programm "PoEdit". By saving the .po file in "PoEdit" the .mo file of the language is automatically being generated. Both files must be updated in version control.
