iTunes library from PC to MAC

Next weekend I will be getting a iMac. I would like to move my iTunes Library to the imac. I would I perform this task? Thanks in advance for your help!

If you have an iPod you can use a program like pod_util from verstion tracker to take the songs off your ipod and it will rebuild the playlist in your iTunes on your iMac. you can also take the folder from the pc and put it on a dvd or 2 and then when you get your imac you can drag the folders with the songs in them directly into itunes and it will import the songs into your library.
