-Now let's turn to the question of how \.{\\hbox} is treated. We actually need to
-consider also a slightly larger context, since constructions like
-
-`\.{\\setbox3=}\penalty0\.{\\hbox...}' and
-`\.{\\leaders}\penalty0\.{\\hbox...}' and
-`\.{\\lower3.8pt\\hbox...}'
-
-are supposed to invoke quite different actions after the box has been packaged.
-Conversely, constructions like `\.{\\setbox3=}' can be followed by a variety of
-different kinds of boxes, and we would like to encode such things in an efficient
-way.
-
-In other words, there are two problems: To represent the context of a box, and to
-represent its type. The first problem is solved by putting a ``context code'' on
-the |save_stack|, just below the two entries that give the dimensions produced by
-|scan_spec|. The context code is either a (signed) shift amount, or it is a large
-integer |>=box_flag|, where |box_flag=@t$2^{30}$@>|. Codes |box_flag| through
-|box_flag+biggest_reg| represent `\.{\\setbox0}' through
-`\.{\\setbox}|biggest_reg|'; codes |box_flag+biggest_reg+1| through
-|box_flag+2*biggest_reg| represent `\.{\\global\\setbox0}' through
-`\.{\\global\\setbox}|biggest_reg|'; code |box_flag+2*number_regs| represents
-`\.{\\shipout}'; and codes |box_flag+2*number_regs+1| through
-|box_flag+2*number_regs+3| represent `\.{\\leaders}', `\.{\\cleaders}', and
-`\.{\\xleaders}'.
-
-The second problem is solved by giving the command code |make_box| to all control
-sequences that produce a box, and by using the following |chr_code| values to
-distinguish between them: |box_code|, |copy_code|, |last_box_code|,
-|vsplit_code|, |vtop_code|, |vtop_code+vmode|, and |vtop_code+hmode|, where the
-latter two are used denote \.{\\vbox} and \.{\\hbox}, respectively.
