The feature request

When building locally while developing, it is possible to accidentally corrupt your real tmpo.db file.

Proposed solution

It would be nice to have an alternative storage location for locally built tmpo binaries while developing, other than ~/.tmpo/tmpo.db, so that real entries don't get corrupted during testing.

This is also useful for testing new features, as the DB might not be formatted the same if it changes in the future.
