Yeah, I wouldn't advocate actually removing "*~", just if we're told
to mess with a file $foo then there's a chance hat there's a messed up
$foo already there or a messed up $foo~, so those two specific files
should be wiped.

Depending on where we do it in the process of moving the old $foo to
$foo~ (wiping the old $foo~), and downloading the new feed into $foo
will alter which of those files we actually want to get rid of.
Starting out before downloading we might have an old $foo, and old
$foo~, or both. After the downloading but before the parsing, the old
$foo~ if any should have been removed, the old $foo should be renamed
$foo~, and the newest version of the feed should be in $foo. Simplest
option would be to remove $foo~ after this whole swapping but before
the parsing; more complicated but potentially more efficient option
would be to remove files earlier on, or maybe even to wrap all the
code regarding this swapping in if(-c =3D=3D true) statements.

Tomorrow I'll take a look at what you've done so far and see where we
should go from there.
