There is some room for failure in the above code Zach. If the number of
items you want is greater than the number actualy in the original file you
will get an "undefined index" error.. It doesn't check that the file path
is valid, and it will overwrite the destination file without warning.
$limit is an artifact that I forgot to eliminate when I wrapped the code
into a function.
In other words, there is a little work for you to do too ;)
