Is there open source software to figure out the long-term / short-term capital gains / losses?

https://bitcointaxes.info

imports trade history from MtGox, Coinbase, Bitstamp, BTC-e, Cryptsy, Bitfinex, Bitfloor, CampBX, LocalBitcoins
manual entry of trades
import/add cost basis for coins owned in 2012 or earlier
calculates short / long term capital gains
uses First-In-First-Out, average costing or "specific identification" (e.g. Last-In-First-Out)
exports data ready to enter on Schedule D Form 8949
exports TurboTax and TaxACT import data
multi-year support for traders before 2013
multi-currency support for your tax country: USD, GBP, EUR, CAD, AUD
calculates gains for alt-coin and cross-coin trading
shows closing positions balances and cost basis for next year
tax estimate calculations for US tax payers
free version for unlimited BTC trades and premium for alt-coins/multi-year

Coming soon:

support for UK, Canada, Australia, Germany tax rules
current year gain and tax liabilities
maintain purchase records from coin addresses
mining income calculators

If you are doing your own taxes, it would make sense to treat bitcoins / alt-coins as capital assets. Although I have read some accountants are filing as a currency but more so they can maximize the amount of taxes paid, to ensure their clients do not underpay. However, if you only have short term gains, you will be paying the maximum anyway.

I have premium and it looks great. Now when can I add my transaction history from wallets and get there value at the time mined? Pretty please?
