#!/usr/bin/env python
# Test file for price database stuff
# To update the price database call
# $PATH/gnucash  --add-price-quotes $PATHTOFILE
# before running this.
# Adding to a calling bash script would be better
# Although calling it from here would be even better!
#  OR:  export PYTHONPATH=$HOME/progs/lib/python2.6/site-packages
# Then: gnucash-env ipython
# The account file is not saved but always use a disposable copy.
# Change, FILE, CURRENCY and STOCK to those defined in your test account.
