+       
+       * ctsim: All functions of command-line tools are now in graphical ctsim
+       
+       * ctsim: added generation of filter images
+
+       * ctsim: Added 2-image math functions (mul, add, div, sub)
 
-       Add help button onto dialog's for reconstruction & projections.
-       Consider use of wxWindows help file classes.
+       * ctsim: Added export of imagefiles to graphic file formats
 
-       Consider changing POL to to read tag tokens.
+       * ctsim: Added support for scaling imagefiles in new sizes
 
-       Consider being able to write Phantom files as text and view as
-       text in ctsim.
+       * ctsim: Added ability to save standard phantom definitions as
+       text files suitable for reading.
