"""
 An offline approximate currency lookup table.
 Used to approximate the sale and budget information for movies.

 Most exchange rates extracted using openexchangerates package on July 13, 2016
 using the following code:

    # first time usage
    from openexchangerates.exchange import Exchange
    app_id = "59354a7e650e4edab76ec7cc20f9ca74"
    local_dir = "~/.openexchangerates"
    exchange = Exchange(local_dir, app_id)

    # After first time usage:
    from openexchangerates.exchange import Exchange
    exchange = Exchange()
    xg = exchange.rates()

 Exchange rates for obsolete currencies are manually added from
    http://coinmill.com/USD_TRL.html?USD=1
