Interesting. I wrote this for myself several years ago.
When I distribute updates, the users download them and run the
installer, which runs the DMM (Database Maintenance Module), which
compares the new schema (database definition) with the one on their
computer, and updates their existing database to match the new schema.
Without this, I'd have to manually update all those databases myself.
