-	Add help button onto dialog's for reconstruction & projections.
-	Consider use of wxWindows help file classes.
+	* ctsim: Added ability to save standard phantom definitions as
+	text files suitable for reading.
+	
+	* ctsim: Add labels for image transformations and display of labels
+	when performing properties of images.
+
+	* processsignal.cpp: Fixed "off by one" bug in
