The die-signal get's tunneled into a subroutine, which get's passed the
string to convert. First I change all the excess 8's to Q's (any non-number
would've done), strip any whitespace, then change the B's to 8's (I needed a
few) then I split the lot in an array of numbers (splitting on any non-number
characters) and translate each number back to the character belonging to that
ASCII value.
undef $\; makes sure I can read the entire DATA in one go and redirecting STDERR
to /dev/null makes sure the nice ASCII-art(ish) text doesn't get printed (on any
non-*nix platform it will get printed anyway ...)
