New class comment for SmalltalkImage:

I represent the current image and runtime environment, including system organization, the virtual machine, object memory, plugins and source files. My instance variable #globals is a reference to the system dictionary of global variables and class names.

My singleton instance is called Smalltalk.

- I represent the SmalltalkImage and partly the VM. Using my current instance you can 
- 	- get the value of some VM parameters, system arguments, vm profiling,
- 	endianess status, external objects,....
  
+ My singleton instance is called Smalltalk.!
- 	- save the image, manage sources

- As you will notice browsing my code I'm a fat class having still too much responsibility.
- But this is life. sd-2 July 2003

- PS: if someone wants to split me go ahead.!
