from preamble:

"Change Set:		CompressedSources
Date:			20 November 2003
Author:			Dan Ingalls

md: fixed for KCP (to call some methods that where moved to
SmalltalkImage).

Changes for Version 1.1:
Fixed a bug in #next, and added #fileID which is needed by OSProcess.

This changeSet defines CompressedSourceStream which writes files as a
series of GZipped segments that can be written and read sequentially
like regular source files, and yet remain compressed by about a factor
of four on the disk.  Useful for developing with full sources on, eg,
PDAs or Squeak PCs with limited file space available.  Full sources for
Squeak 3.6 fit in 3.5MB.

It also defines Smalltalk compressSources, a method that will write a
copy of the sources file in this format, with the extension 'stc' in
place of 'sources'.  Finally, it modifies the openSources:forImage:
method so that it will look first for such a compressed copy, and open
it if found."!
