This release includes a new command, write_reg, which can convert JSON registration data to "XXEVENTS.DBF". It first generates a validation report from the data, then writes the events file with it's best guess about the registrant. Assuming the validation process had high confidence about a database match for the registrant in question, the fields are populated using the database data, not any potential updates from the registrant.
The general syntax of the command is
converter write_reg PERSONNEL.DBF registration.json XXEVENTS.DBF
