 OPTIONS
 =======
 
-There are no options yet.
+-r
+  Highlight multi-byte sequences in reverse video, in the hex output.
+
+-m
+  Monochrome mode. Uses underline, bold, reverse video instead of color.
+  Use this if you have trouble distinguishing the colors, or if they
+  look too much like angry fruit salad.
+  NOT IMPLEMENTED YET.
+
+-o offset
+  Add this amount to the hex offsets (left column). May be negative,
+  if you can think of a reason to want it to be. Can be given in
+  decimal, hex (with *0x* prefix), or octal (with *0* prefix).
+
+-s position
+  Seek in input before starting to dump. Positive *position* means
+  seek from the start of the input. Negative *position* only works
+  on files (not standard input); it means seek backward from EOF.
+  NOT IMPLEMENTED YET.
+

+  Use uppercase hex digits A-F. Default is lowercase.
+  NOT IMPLEMENTED YET.
+
+-h, --help
