+Usage: pixelflip [options] <output_type> <input_file> <output_file> <target_value> <replacement_value>
+Options:
+  --disable-elev           Will disable the elevation
+  --disable-notify         Takes an argument. Arguments are ALL, WARN, 
+                        NOTICE, INFO, FATAL, DEBUG.  If you want multiple 
+                        disables then just do multiple --disable-notify on the 
+                        command line.  All argument are case insensitive.  Default                              is all are enabled.
+  --ossim-logfile          takes a logfile as an argument.  All output messages
+                          are redirected to the specified log file.  By default
+                          there is no log file and all messages are enabled.
+  -K                     specify individual keywords to add to the preferences
+                          keyword list: name=value
+  -P                     specify a preference file to load
+  -T                     specify the classes to trace, ex:
+                          ossimInit|ossimImage.* 
+                          will trace ossimInit and all ossimImage classes
+  -c or --clamp-value      clamp values (any pixel with value larger than input
+                           will be clamped to input)
+  -h or --help             Display this information
+  -m                       Replacement mode (see notes below)
+  -o or --create-overview  Creates and overview for the output image
+  -w                       output tile width(only valid with tiled output
+                           types).  Must be a multiply of 16
+
+
+NOTES:
+-m Replacement mode option explanation:
+   Valid modes = "all", "partial", and "full"  (default=all)
+
+If mode is "all" (default):
+Any pixel with dn of target will be replaced.
+
+If mode is "partial":
+Target will be replaced only at least one subpixel(band) does 
+not have the target.
+
+If mode is "full":
+Target will be repaced only if all subpixels(bands) have the target.
+
+ Example:
+ target      = 0
+ replacement = 1
+ Pixel at (0, 0) r=0, g=0,  b=0
+ Pixel at (0, 1) r=0, g=30, b=21
+
+ Mode is "all":
+ Pixel at (0, 0) becomes  r=1, g=1,  b=1
+ Pixel at (0, 1) becomes  r=1, g=30, b=21
+
+ Mode is "partial":
+ Pixel at (0, 0) remains  r=0, g=0,  b=0
+ Pixel at (0, 1) becomes  r=1, g=30, b=21
+
+ Mode is "full":
+ Pixel at (0, 0) becomes  r=1, g=1,  b=1
+ Pixel at (0, 1) remains  r=0, g=30, b=21
