HowTo view a ROI PAC file? (or "replacement for mdx")

The Problem:
I can't get mdx/dgx in order to view my ROI PAC files.
The Solution:
a Python script called roiview (Get RoiView at ) wich is one of my other scripts.
This script uses pylab and can read, display and save images of ROI PAC quite similar to mdx/dgx.
it can handle *.unw, *.cor, *.slc, *.int and *.dem files.
just download, extract and use:
"roiview -h" for manual.
Update! Oct 13, 2010: A new version of RoiView (0.75) is now available at:
