Babylon is a tool to gather messages, and their translations from property files. It performs a round-trip
consisting of two phases: export phase and import phase. In the export phase the messages are written to a
Google Sheets spreadsheet. A translator will then fill in the missing translations. In the import phase,
the spreadsheet (with the missing translations filled out by a translator) is examined, and the newly translated
messages are used to update the respective translation property files. Also, the state of the translation,
snapshot, is written out to a disk in the form of JSON file. Babylon can be run as a Maven plugin
or as a standalone console application.
