xpnd.c - expand standard input by specified horizontal
and vertical expansion factors. Write the results
to standard output.
In general, this is a pretty worthless program, but if you
process an ascii picture file such as the peanuts characters
that are so popular, or even a nude, the result can be pretty
amazing. A friend of mine and I xpnd'ed a one page nude to be
eleven feet tall! Enjoy.
