Nutter, two questions.

1. Have you talked to the maemo-mapper author about switching database formats and/or integrating your mod into his program?

2. Have you considered (since you're already halfway there) creating a program for Windows and/or Linux that automatically downloads the map files for a given area and automatically builds the database? I ask this because if you've already done this, or are part way there, then there's no need for me to do my script which would essentially be duplicating your work. If not, could you consider it? It'd save me the **** of trying to learn GDBM.
