# Creates a new book file (or *overwrites* an existing one) that has elements
# in it for business use -- intended as a demonstration program.
# Syntax:
# python3 simple_business_create.py \
#                       sqlite3:///home/blah/blah.gnucash
#
# Specifically, this sets up a simple tree, creates a customer, job,
# employee and vendor, creates an unposted invoice for each,
# and posts the customer invoice with a few entries and a tax table.
#
# argv[1] should be the path the new or to overwrite gnucash file/database
# for a file, simply pass the pathname prefixed with the requested data format
# like:
#   xml:///home/blah/blah.gnucash
#   sqlite3:///home/blah/blah.gnucash
# Paths can also be relative, for example:
#   xml://from-here/to/there/blah.gnucash
# For a database you can use these forms:
#   mysql://user:password@host/dbname
#   postgres://user:password@host[:port]/dbname (the port is optional)
#
# You may also want to look at simple_invoice_insert.py
