Archive Utility (formally BOM Archive Helper) is the default archive file handler in Mac OS X. It is a service application that has no GUI when double-clicked, rather it is invoked by opening its associated files or by choosing »Create archive of 'file'« in the Finder's file or contextual menu.
BOM is an abbreviation of »Bill of Materials«. Bill of Materials files or .bom files are used by the Mac OS X Installer program to document where files in an installer bundle are installed, what their file permissions should be, and other file metadata. Thus, a Bill of Materials is read by the Installer, and BOM Archive Helper helps it by extracting the files specified in the BOM.

I prefer Stuffit but this is the default application and it's not half bad. There really isn't an interface.
