Hexd is a versatile replacement for od, to view file contents in a
format similar to MS-DOS DEBUG. by Al Woodhull  vers 0.9  29 May 1998 

README for hexd v. 0.9 29 May 1998

     Hexd displays the contents of a file  or  standard  input  as  a  binary,
     octal, decimal, or hexadecimal dump and/or a display as ASCII characters.
     It writes to its standard output.

     The default output consists of three fields: an index count and a display
     of  16  bytes  in  hexadecimal, followed by a string of the corresponding
     ASCII characters. Periods are substituted for  non-displayable  codes  in
     the character field.

     Hexd is meant to be a replacement for od , with a display similar to  the
     dump  display  of  CP/M  DDT  or  MS-DOS  DEBUG, more convenient than the
     word-oriented display of od for a  little-endian  byte-oriented  machine.
     Previous versions were named xd. This was a bad choice of name because it
     implied that the  program  is  intended  for  use  in  the  MIT  X-Window
     environment.

     Installation: unpack the archive in /usr/local/src.   Cd to the 
     /usr/local/src/hexd directory, type "make",  then "make install".
     The binary will be installed in /usr/local/bin/ and the man page will
     be copied to /usr/local/man/man1/. Do "makewhatis /usr/local/man"
     to update the man page index.
