Primarily, when I first run the program I want it to know my details - the db file, company info, and the default directory for saving files such as pdf's (haven't figured out how to implement that last yet). When you run the program, it starts with a default and errors out if say the db file can't be opened.
Also, if details change, would be easier to update info - such as new business location etc.

I an always hand edit my config file, but thought it would be cleaner if things were done programmatically.
