Detailed Description

This is not actually a file format, but an interface to permit generating multiple binary outputs for Macintosh executables.

This class is needed because Macintosh executables require utilization of the resource fork, a part of the filesystem which is generally unavailable on other platforms. There are multiple ways to represent the resource fork on a non-Macintosh file system, including a separate file, an AppleSingle/AppleDouble container or a MacBinary file. This driver permits generation of one or more of these different formats for the same executable.
