Phone book converter

The PhoneBookConverterApp allows to convert phone book data from:

• CSV files created by Thunderbird into a VCard file that is consumable by Posteo
• VCard files created by Posteo into a CSV file that is consumable by Thunderbird

Build the app by calling ./mvnw package in the project root directory (on Windows, call mvnw package instead).

Run the app by calling e.g., java target\phonebook-converter.jar CsvToVCard csv_source_file vcard_destination_file
