as we might want this kind of table in the future. It is NOT

to be installed in a production system (hence in EXTRA_DIST and

not in the SQL target!)

-- Table with historic business ledger; basically, when the exchange
|
|
-- operator decides to use operating costs for anything but wire
|
|
-- transfers to merchants, it goes in here. This happens when the
|
|
-- operator users transaction fees for business expenses. purpose
|
|
-- is free-form but should be a human-readable wire transfer
|
|
-- identifier. This is NOT yet used and outside of the scope of
|
|
-- the core auditing logic. However, once we do take fees to use
|
|
-- operating costs, and if we still want auditor_predicted_result to match
|
|
-- the tables overall, we'll need a command-line tool to insert rows
|
|
-- into this table and update auditor_predicted_result accordingly.

-- (So this table for now just exists as a reminder of what we'll
|
|
-- need in the long term.)
