I don't see much of a reason why the file slurping wasn't<br>
working...maybe that bit to strip the first line out was a bit too much?<br>
<br>
It took me a bit to figure out why that slurp line looked familiar but<br>
odd:<br>
<br>

<br>
I guess just an example where the less clever option worked out better.<br>
