As I've posted about a few times recently I've moved back to a far more technical role and as a result I've been goofing around with some code...The first thing (which I can talk about ;-)) is a little directory merging utility I've been working on...pretty simple but it was fun to play with. You can find it here if you're interested...along with the main bit of source below...more interesting stuff to come (a lot of the stuff I've been writing is using pre-release bits so I will put it here when you can actually use it!)
