Translation of PCI-s
I have a number of PCI's that I need to translate into several languages. I have found instructions on how to create .po-files for extensions: https://hub.taotesting.com/articles/documentation-for-core-components/internationalization-i18n, and I can see in the PCI-templates that they are prepared for translation (they use __{{Original text}}).
But how are localization folders and files organized in the PCI's? And how do I automatically create po-files from PCI-scripts?
