This is the source code of XFD's SZDD slave, for the curious.

SZDD is a weak LZSS compressor, which was used by Microsoft for many years
in their installation software - all those files with a letter taken from
the end of their extension, eg HELLO.EX_

Thankfully, one day Johnathan Forbes decided to work for Microsoft, and
happened to sell them his LZX compression technology, which is state of the
art as far as LZH is concern. So now Microsoft use LZX compression in their
installation archives, now under the guise of "CAB" files (I'm working on a
CAB slave for xadmaster).

This SZDD slave has only been tested on a few files, so it may not be
entirely perfect. If you have a file it can't extract, please send it to
me.

Note that this slave does not support 'KWAJ' files, which replaced SZDD as
the secret undocumented piss-poor compression format in the 1996 Microsoft
Setup Toolkit. If you have an actual algorithim for this format (or are a
skilled Windows programmer and could hack it out of MSINSSTF.DLL), please
contact me.
