That depends how big the file is.  If it's a gig or two, you might not
be ABLE to do it that way.  If it's smaller but still fairly large,
you might be able, but it would cause you to start swapping.  Besides,
that's not all THAT much easier.

Or you can use -i on the Ruby command line for in-place regex subbing,
just like in Perl.
