// There is a bug https://github.com/cryptocoinjs/btc-transaction/pull/5
// Below works:

// couple of points:

// change the key of scriptPubkey and scriptSig to 'script'. This is something I intend to change
// The bug is at parsing the values. (the values should not be a number and its should be a string)
// e.g. '2000000' rather than 2000000

var binConv = require( "binstring" );
var btcTx = require( "btc-transaction" );

// This is basically the issue we had. I will make a fix and hopefully can merge today
