Tired of wondering why your apps are so enormous?  Ever wonder what lives
inside an object file, and where?

MachOViewer is a NeXTStep app that is supposed to aid in the visualization
of Mach-O object files.

It draws a picture of what a Mach-O file could look like in memory.
It allows for "zooming" on an address range of interest, displaying
Mach-O "segment" names, addresses of the segments, and names of the
sections of the segments.

For Mach-O object files that reference shared libraries, MachOViewer allows
the display of those shared libraries as they fit in the object file's
address space.

The file /usr/include/mach-o/loader.h is mostly what I used to concoct
the in-memory representation of the file.

I wrote and tested this app under NeXTStep 3.2 on a 25MHz color
NeXTStation (68040).  The MachOViewer app does not understand "fat" or
multi-architecture binaries, and it may require some hacking to get to
work on an i386 architecture machine.

The source files include some subsidiary classes that may be of interest
for other projects.

MachOFile.m - a class used to manipulate Mach-O format object files
	LoadCommand.m - used internally by MachOFile objects
	SortedList.m  - Don MacGregor's subclass of List
	MappedFile.m  - simplistic Mach-style memory mapped file class

Queue.m           - a simple FIFO queue or LIFO stack class.

Thesed files may illustrate how the MachOFile class can be used elsewhere.
I wrote them to test the MachOFile class outside of an IB context.
