I'm -1 on XML as an intermediate format, and -2 on HTML. I'm currently
tending towards the idea that we should initially just implement text,
since that will solve a lot of problems at a reasonable level (and
people can still use scriptindex), and then we can think about more
complex things later. (*Possibly* we could have the filter mechanism
use any of the internal parsers, meaning if you really wanted to
convert to HTML and parse that for extra metadata, you could.)

Trust the OS to manage $TMPDIR correctly. On any well-tuned decent OS
it'll be efficient. (On many it'll actually be a tmpfs anyway.)
