This one is almost blatently obvious, but I felt like submitting it anyways.
We assign $_ to a long string of numbers, split those numbers into pairs of 3
with a space in between.
Then we simply split the numbers by that space and stuff them into @m, go through
each entry of @m and chr it, if it is a number. Even though we don't need to check that
$_ is numeric for it to work, if we don't then it messes up badly running with -w.
So, basically the string at the start is the ascii ordinal values for The Perl Journal,
and the tabs/newlines to format it.
