Sorry, should've said in the current directory and below (it recurses).

And that to delete the swap file you must enter y or Y, anything else
will leave it (better safe than sorry).

And it's probably horribly unportable, and not nicely written, and
horribly documented (i.e undocumented), but it was basically hacked
together once I got sick enough of recovering swap files more manually,
and it works for me on Mac OS X.

So I don't really want to promote it...but if it helps you, great!

And by 'it' I mean something like this, not this as it stands....
