It is split into - /libgnucash (for the non-gui bits) - /gnucash (for the gui) - /common (misc source files used by both) - /bindings (currently only holds python bindings) This is the first step in restructuring the code. It will need much more fine tuning later on.

# Opens a GnuCash book file and adds an invoice to it for a particular
|
|
# customer (by ID) with a specific ID and value
|
|
# Optionally also adds a payment for the invoice as well
|

#
|
|
# The account tree and tax tables are assumed to be the same as the ones
|
|
# created in simple_business_create.py, but you can edit that to adapt
|
|
# this to become an invoice importer for your own books
