+/* 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
+ *	       consequtive 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
+ *	    (antonio.colombo@jrc.it)
+ * 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 merege 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.
