token lists produced by `^|\the|' are not expanded further. Furthermore
a token following `^|\noexpand|' will not be expanded, since its ability
to expand has been nullified. These two operations can be used to control
^^{expansion, avoiding} what gets expanded and what doesn't.

\ddanger \TeX's primitive command |\shipout|\<box> is what actually
causes output. It sends the contents of the box to the |dvi| file,
which is \TeX's main output file; after \TeX\ has finished,
the ^|dvi| file will contain a compact device-independent encoding of
instructions that specify exactly what should be printed.  When a
box is shipped out, \TeX\ displays the values of\/ |\count0| through
|\count9| on your terminal, ^^|\count0| as explained in Chapter~15; these
ten counters are also recorded in the |dvi| file, where they can be used
to identify the page. All of the ^|\openout|, ^|\closeout|, and ^|\write|
commands that appear inside of the \<box> are performed in their natural
order as that box is being shipped out. Since a |\write| command
expands macros, as explained in Chapter~21, \TeX's scanning mechanism
might detect syntax errors while a |\shipout| is in progress. If
^|\tracingoutput| is nonzero at the time of a |\shipout|, the contents
of the \<box> being shipped are written into your log file in symbolic
form. You can say |\shipout| anywhere, not only in an output routine.

The mysterious negative ^|\kern| here cancels out the natural space of the
^|\topskip| glue that goes above the empty |\line|; that empty line box
prevents the ^|\vfill| from disappearing into a page break.  The vertical
list that results from |\dosupereject| is placed on \TeX's list of things
to put out next, just after the straggling insertions have been
reconsidered as explained in Chapter~15. Hence another super-eject will
occur, and the process will continue until no insertions remain.
