-% Allocation of registers
-
-% Here are macros for the automatic allocation of \count, \box, \dimen,
-% \skip, \muskip, and \toks registers, as well as \read and \write
-% stream numbers, \fam codes, \language codes, and \insert numbers.
-
-% When a register is used only temporarily, it need not be allocated;
-% grouping can be used, making the value previously in the register return
-% after the close of the group. The main use of these macros is for
-% registers that are defined by one macro and used by others, possibly at
-% different nesting levels. All such registers should be defined through
-% these macros; otherwise conflicts may occur, especially when two or more
-% macro packages are being used at once.
-
-% The following counters are reserved:
-% 0 to 9 page numbering
-% 10 count allocation
-% 11 dimen allocation
-% 12 skip allocation
-% 13 muskip allocation
-% 14 box allocation
-% 15 toks allocation
-% 16 read file allocation
-% 17 write file allocation
-% 18 math family allocation
-% 19 language allocation
-% 20 insert allocation
-% 21 the most recently allocated number
-% 22 constant -1
-% New counters are allocated starting with 23, 24, etc. Other registers are
-% allocated starting with 10. This leaves 0 through 9 for the user to play
-% with safely, except that counts 0 to 9 are considered to be the page and
-% subpage numbers (since they are displayed during output). In this scheme,
-% \count 10 always contains the number of the highest-numbered counter that
-% has been allocated, \count 14 the highest-numbered box, etc.
-% Inserts are given numbers 254, 253, etc., since they require a \count,
-% \dimen, \skip, and \box all with the same number; \count 20 contains the
-% lowest-numbered insert that has been allocated. Of course, \box255 is
-% reserved for \output; \count255, \dimen255, and \skip255 can be used freely.
-
-% It is recommended that macro designers always use
-% \global assignments with respect to registers numbered 1, 3, 5, 7, 9, and
-% always non-\global assignments with respect to registers 0, 2, 4, 6, 8, 255.
-% This will prevent ``save stack buildup'' that might otherwise occur.
