# Marking the ZIP intermediate makes sure it is automatically deleted after
# generating the SQLite database while we don't always re-download it.
# Effectively, it will behave like a temporary file.
# NOTE: This is disabled for the time being since the database schema changes
# from time to time, so a rebuild could easily break the script.
# Instead, we add the file to Git, so every clone is guaranteed to contain
# a database matching the openrussian.lua script.
