btctrade was written on a GNU operating system, but it should be able to run on
any system that runs Ruby.


To run this software:

Go to <http://www.bitcoinwatch.com/> and click on "historical data" at the
bottom of the page. Save the file to the directory containing the btctrade
program. Run the following commands from that directory:

$ unzip trades.zip
$ ./btctrade trades.csv >tradedate.csv

The standard output of btctrade is a new csv file with the 'datetime' field
converted to a nice, legible date.
