This is a free Windows command-line program. It removes one specific 
backward-compatibility problem between Acrobat 4 Distiller and Acrobat 3 
Reader. The symptom of this problem is the message "Could not find the 
ColorSpace named 'Cs9'" or Cs6, etc.

The program will either leave your PDF file unchanged, or will do minimal 
changes to remove this specific problem. If it helps you, great. If your 
PDF file has any other problem or uses any other Acrobat 4 (PDF 1.3) 
feature, it won't help that.

Disclaimer: This program is not sponsored by my employer. It was written 
from the language description in the PDF Reference Manual, and contains no 
Adobe source code, libraries, or other technology. It is 500 lines of C 
that I wrote it one weekend to solve a specific problem I had.
