# [texhax] Changing \skip\footins locally

Here's a try at a solution.  It appends a \changefoot command to the end
of the \output routine.  By redefining \changefoot, you can sneak
changes into the page measurements, and have them reflected in the pages
you're outputting.

Warning: this isn't what you'd call kosher, since messing with \output
often has unexpected consequences, but in the context of trying to muck
around with the final copy of a particular book, you may find it useful.
Note that I think you'll need to change the \changefoot definition
somewhere on the previous page to the one you're trying to fidget with.
But mess around with this, and I bet you'll see how to make it work for
you.

Hope this helps,
