Convert invisible (binary) characters to a visible form
Copyright c 1989-1994 by William Deich.
Viz copies its input to its output, converting invisible characters to a visible form. If the -t option is used, the output is formatted in a form that can be completely inverted by inviz, which allows a binary file to be converted to a text form and then back. It is much more flexible than either cat -v or od either old or POSIX od, and it is also 2-4 times faster.
