/* xxd: my hexdump facility. jw
*
* 2.10.90 changed to word output
* 3.03.93 new indent style, dumb bug inserted and fixed.
* -c option, mls
* 26.04.94 better option parser, -ps, -l, -s added.
* 1.07.94 -r badly needs - as input file. Per default autoskip over
* consecutive lines of zeroes, as unix od does.
* -a shows them too.
* -i dump as c-style #include "file.h"
* 1.11.95 if "xxd -i" knows the filename, an 'unsigned char filename_bits[]'
* array is written in correct c-syntax.
* -s improved, now defaults to absolute seek, relative requires a '+'.
* -r improved, now -r -s -0x... is supported.
* change/suppress leading '\0' bytes.
* -l n improved: stops exactly after n bytes.
* -r improved, better handling of partial lines with trailing garbage.
* -r improved, now -r -p works again!
* -r improved, less flushing, much faster now! (that was silly)
* 3.04.96 Per repeated request of a single person: autoskip defaults to off.
* 15.05.96 -v added. They want to know the version.
* -a fixed, to show last line inf file ends in all zeros.
* -u added: Print upper case hex-letters, as preferred by unix bc.
* -h added to usage message. Usage message extended.
* Now using outfile if specified even in normal mode, aehem.
* No longer mixing of ints and longs. May help doze people.
* Added binify ioctl for same reason. (Enough Doze stress for 1996!)
* 16.05.96 -p improved, removed occasional superfluous linefeed.
* 20.05.96 -l 0 fixed. tried to read anyway.
* 21.05.96 -i fixed. now honours -u, and prepends __ to numeric filenames.
* compile -DWIN32 for NT or W95. George V. Reilly, * -v improved :-)
* support --gnuish-longhorn-options
* 25.05.96 MAC support added: CodeWarrior already uses ``outline'' in Types.h
* which is included by MacHeaders (Axel Kielhorn). Renamed to
* xxdline().
* 7.06.96 -i printed 'int' instead of 'char'. *blush*
* added Bram's OS2 ifdefs...
* 18.07.96 gcc -Wall @ SunOS4 is now slient.
* Added osver for MSDOS/DJGPP/WIN32.
* 29.08.96 Added size_t to strncmp() for Amiga.
* 24.03.97 Windows NT support (Phil Hanna). Clean exit for Amiga WB (Bram)
* 02.04.97 Added -E option, to have EBCDIC translation instead of ASCII
* (azc10@yahoo.com)
* 22.05.97 added -g (group octets) option (jcook@namerica.kla.com).
* 23.09.98 nasty -p -r misfeature fixed: slightly wrong output, when -c was
* missing or wrong.
* 26.09.98 Fixed: 'xxd -i infile outfile' did not truncate outfile.
* 27.10.98 Fixed: -g option parser required blank.
* option -b added: 01000101 binary output in normal format.
* 16.05.00 Added VAXC changes by Stephen P. Wall
* 16.05.00 Improved MMS file and merge for VMS by Zoltan Arpadffy
*
* (c) 1990-1998 by Juergen Weigert (jnweiger@informatik.uni-erlangen.de)
*
* Small changes made afterwards by Bram Moolenaar et al.
*
* Distribute freely and credit me,
* make money and share with me,
* lose money and don't ask me.
