OCI HK Merge Utility
Usage:
java -jar oci_hk_merge.jar "<path to legacy export>" "<path to fm db.txt>" "<path to dau db.txt>" "<output file path base>"
java -jar xina_import.jar -d output_dir/
Note that "<output file path base>" is the base name for output files (so C:/out would generate C:/out.tsv, C:/out.json, etc).
