+Updates in 2.0 Release
+----------------------
+
+ 1. Merged scale & operations to single flag
+ v1.0 had normalize/equalize handled by "-e" flag and rest of
+ image operations by "-s" flag. Both are merged into "-s" in
+ this release.
+
+ 2. New option to clip image min/max
+ You can limit the pixel-values in output image using the flag
+ "-r". For eg: -r 10:300 to generate jpegs with pixel values in
+ the range 10 to 300.
+
+ 3. New option to negate image option
+ A negative image can be generated using "-n" flag.
+
+ 4. New option to resize image
+ zoom or shrink output image using "-z <zoomfact>".
+
+ 5. New option to choose jpeg quality factor
+ You can choose the jpeg quality factor using "-q <quality>"
