user5312: Blockchain.info provides this functionality in a simple API like so:
https://blockchain.info/rawtx/fc15f762e8dbbdd407534047ef2a9211ca0e79c3625d5fe73cdacade4f9118d6
However, I would prefer to make this query directly against the network blockchain rather than to a third party like blockchain.info.

user10621: You can use JSON-RPC to achieve this. The only missing information will be the relayed_by field.
To use the JSON-RPC API of your client edit your bitcoin.conf file like this
rpcuser=user 
rpcpassword=password 
rpcport=8332
server=1

Then you can use a library to query the API like JSON-RPC for PHP
You can also do it on a much easier way by using the command line
./bitcoind getblock c15f762e8dbbdd407534047ef2a9211ca0e79c3625d5fe73cdacade4f9118d6
