How do you assemble a cab file?

Is there a tutorial or a utility out there for assembling a cab file? I have edited xml files and BMPs ready to go but I don't know how to compress them into a cab file. Any help would be greatly appreciated.

Or use CabPack, which has an easy-to-use Windows GUI bolted onto the front of Cabdir - much simpler. Available here (http://www.softpedia.com/get/File-manag ... Pack.shtml)
Happy new year, all!

I did it! I assembled a cab file using CabPack. I'm on a roll again. Thanks for the help and Happy New Year!
