The kind we were discussing before we wandered off topic and Frank

A proposed `journal' or `proceedings' class which redefines
\documentclass and other preamble commands such that `self standing'

Number of pages is more or less irrelevant to memory use. Source2e has
almost no cross references (sadly:-) so is quite light on memory
consumption. It is *slow* because all the verbatim bits are parsed `by

automatically print themselves verbatim even though they are not
marked up as LaTeX.

Yes that as well, but to be reliable for that use the pages generated
have to be *exactly* correct and it is always difficult to be sure of
that with an include system. So you \includeonly{chapter3} but the
