-For now, read the header comments inside each of these for documentation.
-The programs are simple enough that they don't really need a Makefile any more
-complex than the one given; ymmv.  Data and xor may also be useful on DOS,
-which is why there are hooks for it in the code.
-
-data.c		a primitive atob / btoa byte generator
-*.d		example input to "data -g"
-rservice.c	a utility for scripting up rsh/rexec attacks
-xor.c		generic xor handler

-   With no args, xors stdin against 0xFF to stdout.  A single argument is a

-   as the end; if you need to xor against a string that *includes* zeros,
-   you're on your own.
-
-   The indirect file can be generated easily with data.c.
-
-   Written because there are so many lame schemes for "masking" plaintext
-   passwords and the like floating around, and it's handy to just run an
-   obscure binary-format configuration file through this and look for strings.
