Invoice & payment import script

[Reuben Cummings]

I wrote a script to import invoices and payments into the gnucash
database. It seems to work ok but in the accounts payable register,
the 'Type' column displays '?' instead of 'P' or 'I'. Is there a
setting in the database that controls this behavior or will I have to
modify each transaction in the register individually? Also, is there
anything I should be careful of with the database?
