[colug-432] Command-line Snow Emergency Level

[Mike Plemmons]

This is a cool little script but for anyone running Debian 8.0 there is a
change to the xpath command.  The '-q' argument fails to work.  I have to
use this argument structure.

xpath "$tmpfile" "//div[@class='main']/div//text()"


Usage:
/home/mike/perl5/bin/xpath [filename] query
