- to TeX 3.141592.
-
- * tex.ch1, tex.ech: Change the xmalloc_array calls to the `new'
- interface (from 2001-11-10).
-
- * etex.ch0, etex.ch1, etex.fix, tex.ch2: Removed.
-
- * etex.mk: Rewrite build rules for etex.{web,ch}, add
- etexdir/etex.mk and remove etex.{ch0,ch1,fix}, tex.ch2.
-
- * etex.version: add newline.
-
- * etrip/etrip.log, etrip.diffs: changed due to bug fix.
-
-2004-07-14 Olaf Weber <olaf@infovore.xs4all.nl>
-
- * etex.fix: Add fix for typo on line 2737 of etex.ch. From Peter
- Breitenlohner.
-
- * etexextra.h: Add BUG_ADDRESS.
-
-2004-07-04 Olaf Weber <olaf@infovore.xs4all.nl>
-
- * etex.mk: Move the creation of the format-related links to
- format-related install rules; this seems to be a better place for
- them, as the links are pointless without the corresponding
- formats. Make the install-*-pool rules depend on the pool file in
- question.
-
-2004-07-03 Olaf Weber <olaf@infovore.xs4all.nl>
-
- * etex.mk: Set up the make rules so that if etex isn't built (by
- default) we do not forward from the general to the etex-specific
- rules. But the etex-specific rules can be used.
-
- * etex.mk: Use $(TANGLE), $(TIE) instead ./tangle, ./tie to
- support cross-compiling.
-
-2004-05-10 Olaf Weber <olaf@infovore.xs4all.nl>
-
- * etex.mk (install-etex-programs): Typo resulted in no etex binary
- being installed.
-
-2004-05-08 Olaf Weber <olaf@infovore.xs4all.nl>
-
- * etex.mk (install-etex-programs): This rule didn't have a command
- attached, so etex didn't get installed.
- (install-etex-links): Dont install einitex, evirtex links.
-
- * etex.mk: Formats are now parked in a subdirectory of
- $(web2cdir).
-
- * etex.mk: Change the .efmt extension to .fmt. One consequence is
- that we don't want to build tex.fmt, where we could safely build
- tex.efmt.
-
- * etexextra.h: .efmt -> .fmt.
-
- * tex.ech: .efmt -> .fmt.
-
-2004-01-27 Olaf Weber <olaf@infovore.xs4all.nl>
-
- * etex.fix: The assignment to cur_val instead of cur_val_level
- would result in \lastnodetype getting confused about what type of
- value it was supposed to be. Reported by Hartmut Henkel
- <hartmut_henkel@gmx.de>, fix found by Fabrice Popineau
- <Fabrice.Popineau@supelec.fr>.
-
-2003-02-19 Olaf Weber <olaf@infovore.xs4all.nl>
-
- * etex.mk: Installation of formats is no longer done via
- install-data in this file, but just from the install-data ->
- install-dumps -> install-fmts in the main Makefile. That way we
- can prevent automatic installation with a single change in that
- Makefile.
- (etex.p): Depend on tangle.
- (triptrap): Depend on etrip.
- (install-etex-data): Double-colon rule.
- (install-data): Combine with install-etex-data.
-
-2003-02-17 Olaf Weber <olaf@infovore.xs4all.nl>
-
- * etex.ch1: Reduce to banner changes.
-
- * etex.ch0: Slightly extend the reverted bits here, so they can be
- cleared out of etex.ch1 and are now all in one file.
-
-2003-02-16 Olaf Weber <olaf@infovore.xs4all.nl>
-
- * etex.ch1: Correct the banners, and revert a final few bits of
- TeX that use a variable that doesn't exist in e-TeX.
-
- * etex.ch0: TeX 3.141592 and e-TeX 2.1 require reconciliation.
- Revert some of TeX's code to 3.14159 to get e-TeX 2.1 to tangle.
-
- * etexextra.h: Update banner for 3.141592-2.1.
-
- * etex.mk (etex.web): Add etex.ch0 and etex.ch1 to build rules.
-
-2003-02-15 Olaf Weber <olaf@infovore.xs4all.nl>
-
- * etex.mk: From klibtool to libtool. Based on patches from Albert
- Chin-A-Young <china@thewrittenword.com>.
-
- * etex.mk: Changes to make e-TeX, in extended mode, the engine
- under LaTeX2e.
-
-2003-02-07 Olaf Weber <olaf@infovore.xs4all.nl>
-
- * etex.mk: Reorganized to match the new Makefile.in.
-
-2003-01-15 Olaf Weber <olaf@infovore.xs4all.nl>
-
- * etex.mk (etestenv): Add LC_ALL=C to the etrip environment.
-
-2002-10-11 Olaf Weber <olaf@infovore.xs4all.nl>
-
- * tex.ch1: Settle on a text for the not-TeX banner.
-
-2002-06-02 Olaf Weber <olaf@infovore.xs4all.nl>
-
- * tex.ch0, tex.ch1: Changes to account for the banner changing
- when certain options are specified that make the program
- not-strictly TeX.
-
- * tex.ch2: Commented-out changes deleted. These changes became
- active in tex.ch1.

- (by Karl Berry, as of Feb 7 1997.
-
- All e-TeX (and e-TRIP) source files as well as a Makefile fragment
- are in a separate directory: web2c/etexdir. This will certainly make
- it easier to switch to e-TeX Version 2.

-this is essentially the depth of |push| commands in the \.{DVI} output.

-For mixed direction text (\TeXXeT) the current text direction is called
-|cur_dir|. As the box being shipped out will never be used again and
-soon be recycled, we can simply reverse any R-text (i.e., right-to-left)
-segments of hlist nodes as well as complete hlist nodes embedded in such
-segments. Moreover this can be done iteratively rather than recursively.
-There are, however, two complications related to leaders that require
-some additional bookkeeping: (1)~One and the same hlist node might be
-used more than once (but never inside both L- and R-text); and
-(2)~leader boxes inside hlists must be aligned with respect to the left
-edge of the original hlist.
-
-A math node is changed into a kern node whenever the text direction
-remains the same, it is replaced by an |edge_node| if the text direction
-changes; the subtype of an an |hlist_node| inside R-text is changed to
-|reversed| once its hlist has been reversed.

-@* \[53a] The extended features of \eTeX.
-The program has two modes of operation: (1)~In \TeX\ compatibility mode
-it fully deserves the name \TeX\ and there are neither extended features
-nor additional primitive commands. There are, however, a few
-modifications that would be legitimate in any implementation of \TeX\
-such as, e.g., preventing inadequate results of the glue to \.{DVI}
-unit conversion during |ship_out|. (2)~In extended mode there are
-additional primitive commands and the extended features of \eTeX\ are
-available.
-
-The distinction between these two modes of operation initially takes
-place when a `virgin' \.{eINITEX} starts without reading a format file.
-Later on the values of all \eTeX\ state variables are inherited when
-\.{eVIRTEX} (or \.{eINITEX}) reads a format file.
-
-The code below is designed to work for cases where `$|init|\ldots|tini|$'
-is a run-time switch.
-

-if not no_new_control_sequence then {just entered extended mode ?}
- no_new_control_sequence:=true@+else
-
-@ The \eTeX\ features available in extended mode are grouped into two
-categories: (1)~Some of them are permanently enabled and have no
-semantic effect as long as none of the additional primitives are
-executed. (2)~The remaining \eTeX\ features are optional and can be
-individually enabled and disabled. For each optional feature there is
-an \eTeX\ state variable named \.{\\...state}; the feature is enabled,
-resp.\ disabled by assigning a positive, resp.\ non-positive value to
-that integer.

-@ The optional |TeXXeT| feature of \eTeX\ contains the code for mixed

-MacKay in {\sl TUGboat\/} {\bf 8}, 14--25, 1987.
-@^Knuth, Donald Ervin@>
-@^MacKay, Pierre@>
-
-In order to avoid confusion with \TeXeT\ the present implementation of
-mixed direction typesetting is called \TeXXeT. It differs from \TeXeT\
-in several important aspects: (1)~Right-to-left text is reversed
-explicitly by the |ship_out| routine and is written to a normal \.{DVI}
-file without any |begin_reflect| or |end_reflect| commands; (2)~a
-|math_node| is (ab)used instead of a |whatsit_node| to record the
-\.{\\beginL}, \.{\\endL}, \.{\\beginR}, and \.{\\endR} text direction
-primitives in order to keep the influence on the line breaking algorithm
-for pure left-to-right text as small as possible; (3)~right-to-left text
-interrupted by a displayed equation is automatically resumed after that
-equation; and (4)~the |valign| command code with a non-zero command
-modifier is (ab)used for the text direction primitives.
-
-Nevertheless there is a subtle difference between \TeX\ and \TeXXeT\
-that may influence the line breaking algorithm for pure left-to-right
-text. When a paragraph containing math mode material is broken into
-lines \TeX\ may generate lines where math mode material is not enclosed
-by properly nested \.{\\mathon} and \.{\\mathoff} nodes. Unboxing such
-lines as part of a new paragraph may have the effect that hyphenation is
-attempted for `words' originating from math mode or that hyphenation is
-inhibited for words originating from horizontal mode.
-
-In \TeXXeT\ additional \.{\\beginM}, resp.\ \.{\\endM} math nodes are
-supplied at the start, resp.\ end of lines such that math mode material
-inside a horizontal list always starts with either \.{\\mathon} or
-\.{\\beginM} and ends with \.{\\mathoff} or \.{\\endM}. These
-additional nodes are transparent to operations such as \.{\\unskip},
-\.{\\lastpenalty}, or \.{\\lastbox} but they do have the effect that
-hyphenation is never attempted for `words' originating from math mode
-and is never inhibited for words originating from horizontal mode.

-@ \eTeX\ (in extended mode) supports 32768 (i.e., $2^{15}$) count,
-dimen, skip, muskip, box, and token registers. As in \TeX\ the first
-256 registers of each kind are realized as arrays in the table of
-equivalents; the additional registers are realized as tree structures
-built from variable-size nodes with individual registers existing only
-when needed. Default values are used for nonexistent registers: zero
-for count and dimen values, |zero_glue| for glue (skip and muskip)
-values, void for boxes, and |null| for token lists (and current marks
-discussed below).
-
-Similarly there are 32768 mark classes; the command \.{\\marks}|n|
-creates a mark node for a given mark class |0<=n<=32767| (where
-\.{\\marks0} is synonymous to \.{\\mark}). The page builder (actually
-the |fire_up| routine) and the |vsplit| routine maintain the current
-values of |top_mark|, |first_mark|, |bot_mark|, |split_first_mark|, and
-|split_bot_mark| for each mark class. They are accessed as
-\.{\\topmarks}|n| etc., and \.{\\topmarks0} is again synonymous to
-\.{\\topmark}. As in \TeX\ the five current marks for mark class zero
-are realized as |cur_mark| array. The additional current marks are
-again realized as tree structure with individual mark classes existing
-only when needed.

-@ There are seven almost identical doubly linked trees, one for the
-sparse array of the up to 32512 additional registers of each kind and
-one for the sparse array of the up to 32767 additional mark classes.
-The root of each such tree, if it exists, is an index node containing 16
-pointers to subtrees for 4096 consecutive array elements. Similar index
-nodes are the starting points for all nonempty subtrees for 4096, 256,
-and 16 consecutive array elements. These four levels of index nodes are
-followed by a fifth level with nodes for the individual array elements.
-
-Each index node is nine words long. The pointers to the 16 possible
-subtrees or are kept in the |info| and |link| fields of the last eight
-words. (It would be both elegant and efficient to declare them as
-array, unfortunately \PASCAL\ doesn't allow this.)
-
-The fields in the first word of each index node and in the nodes for the
-array elements are closely related. The |link| field points to the next
-lower index node and the |sa_index| field contains four bits (one
-hexadecimal digit) of the register number or mark class. For the lowest
-index node the |link| field is |null| and the |sa_index| field indicates
-the type of quantity (|int_val|, |dimen_val|, |glue_val|, |mu_val|,
-|box_val|, |tok_val|, or |mark_val|). The |sa_used| field in the index
-nodes counts how many of the 16 pointers are non-null.
-
-The |sa_index| field in the nodes for array elements contains the four
-bits plus 16 times the type. Therefore such a node represents a count
-or dimen register if and only if |sa_index<dimen_val_limit|; it
-represents a skip or muskip register if and only if
-|dimen_val_limit<=sa_index<mu_val_limit|; it represents a box register
-if and only if |mu_val_limit<=sa_index<box_val_limit|; it represents a
-token list register if and only if
-|box_val_limit<=sa_index<tok_val_limit|; finally it represents a mark
-class if and only if |tok_val_limit<=sa_index|.
-
-The |new_index| procedure creates an index node (returned in |cur_ptr|)

-\section Introduction.
-Let us first review the process of generating an implementation of
-\TeX82 for a particular system from the source files as, e.g., described
-in the \.{WEB} manual [1]. The system-independent source file
-\.{tex.web} must remain unmodified. All changes to \.{tex.web}
-necessary for a particular operating system and\slash or compiler are to
-be collected in a system-dependent change file, typically named
-\.{tex.ch}. Both files \.{tex.web} and \.{tex.ch} are effectively
-merged when input by the \.{WEB} system programs \.{WEAVE} and
-\.{TANGLE}. When \.{WEAVE} processes this merged input, a file
-\.{tex.tex} is produced. Further processing by \TeX\ yields a `pretty
-printed' version of the input together with an index.
-
-When \.{TANGLE} processes the merged input, a string pool file
-\.{tex.pool} and a Pascal file \.{tex.pas} (or similar) are produced.
-The Pascal file can then be further processed by a suitable compiler
-and\slash or language converter such as \.{web2c}, and eventually yields
-an executable program.
-
-There are actually three versions of the program: First there is
-\.{INITEX} with its capability to initialize all of \TeX's tables and to
-write them in compact form to a format file. Next there is the
-production version \.{VIRTEX} requiring a format file as input. Finally
-there is \.{TRIPTEX}, a version of \.{INITEX} with special values for
-some of \TeX's parameters, for the \.{TRIP} test [2] that should be used
-to validate a \TeX\ implementation. Depending on the capabilities of
-the compiler, these three versions of the program are generated from
-three slightly different change files or they are generated from one
-change file with different compiler options. They might even be one and
-the same executable program used with different run time options.
-

-\section Generating \eTeX.
-The process of generating \eTeX\ is essentially the same as that of
-generating \TeX\ as described above. Conceptually there is a
-system-independent source file \.{etex.web} and a system-dependent change
-file \.{etex.sys}. Processing these two files by \.{TANGLE} yields a
-string pool file \.{etex.pool} as well as a Pascal file \.{etex.pas},
-whilst processing by \.{WEAVE} produces a \TeX\ source file, \.{etex.tex}.
-
-It may, however, be necessary to increase some of the constants defined
-in \.{TANGLE} and \.{WEAVE}. The following values should suffice in
-most cases:
-$$
-\vcenter{\halign{$#$\hfil\qquad&#\hfil\cr
-\\{max\_bytes}\times\\{ww}=100~000&\.{TANGLE} and \.{WEAVE}\cr
-\\{max\_texts}=2~500&\.{TANGLE} and \.{WEAVE}\cr
-\\{max\_toks}\times\\{zz}=180~000&\.{TANGLE}\cr
-\\{max\_names}=5~000&\.{TANGLE}\cr
-\\{max\_scraps}=3~000&\.{WEAVE}\cr
-\\{stack\_size}=300&\.{WEAVE}\cr
-}}
-$$
-
-The source file \.{etex.web} for \eTeX\ does not, however, exist as a
-physical file. It is the hypothetical file obtained by applying the
-changes in the actual source file \.{etex.ch} to \.{tex.web}. Thus
-\.{etex.web} inherits the bulk of code from \.{tex.web}, whilst the
-system-independent source file \.{etex.ch} for \eTeX\ defines the
-differences between \.{etex.web} and \.{tex.web}. In order to generate
-an implementation of \eTeX\ two change files have to be applied to
-\.{tex.web}, one after the other (the actual file names may differ):
-$$
-\vcenter{\halign{#\hfil&\qquad\.{#}\hfil&\qquad#\hfil\cr
-0.&tex.web&system-independent \.{WEB} source for \TeX\cr
-1.&etex.ch&system-independent changes for \eTeX\cr
-2.&etex.sys&system-dependent changes for \eTeX\cr
-}}
-$$
-
-The process of merging several change files into \.{tex.web} should
-certainly not be performed by hand. There are programs such as \.{TIE}
-and \.{PATCHWEB} that perform this process automatically. If no such
-program is available, a \TeX\ program \.{WEBMERGE} can be used.
-\.{WEBMERGE} reads \.{tex.web} and up to nine change files and produces
-a merged change file that can then be processed, together with
-\.{tex.web}, by \.{TANGLE} and \.{WEAVE}. [On systems such as VMS, use
-of \.{WEBMERGE} can leave a large number of temporary files
-lying around; this can be avoided by setting a version limit (e.g.~1) on any
-existing versions of those files, or by setting a version limit on the
-directory in which they will be created. On other systems, it will probably
-leave one large temporary file.]
-
-Every implementor of \eTeX\ is responsible for creating and maintaining
-a suitable \.{etex.sys} in the same way as every implementor of \TeX\
-is responsible for creating and maintaining \.{tex.ch}. Since the bulk
-of code in \.{etex.web} is identical to that in \.{tex.web} the bulk of
-the system-dependent changes in \.{etex.sys} for a particular system
-will be identical to those in \.{tex.ch} for the same system. In the
-following we try to give some hints where \.{etex.sys} for a particular
-system might deviate from the corresponding \.{tex.ch}.
-
-First, it might be necessary to increase the size of \TeX's string pool
-in order to accommodate \eTeX's additional strings (message texts as
-well as multi-letter control sequences). If this turns out to be
-necessary for \eTeX\ it would certainly not be harmful to do it for
-\TeX\ as well. \TeX\ and \eTeX\ use three constants related to the
-string pool: \\{max\_strings} the maximal number of strings,
-\\{pool\_size} the maximal number of string characters, and
-\\{string\_vacancies} the minimal number of available string characters
-in addition to those occupied by strings from the pool file. It is,
-therefore, sufficient to increase \\{pool\_size} (or reduce
-\\{string\_vacancies}) by the number of \eTeX's additional string
-characters and to increase \\{max\_strings} by the number of \eTeX's
-additional strings. The latter will, however, be unnecessary for most
-implementations as \\{max\_strings} is usually increased substantially
-beyond its standard value in order to accommodate large \TeX\ macro
-packages.
-
-For Version~2 of \eTeX, there are about 100 additional strings with
-about 1500 additional string characters. The precise numbers can be
-obtained by running \.{POOLTYPE} on \TeX's and \eTeX's pool files
-(\.{POOLTYPE} reports the total number of strings and string characters
-in a pool file).
-
-Next, \.{etex.sys} may contain a system-dependent modification of the
-\\{eTeX\_banner} string. The modified \\{eTeX\_banner} string must
-contain `\.{e-TeX}' as well as the \eTeX\ version number. Note,
-however, that the \\{banner} string modified by \.{tex.ch} will not be
-referenced by \eTeX\ unless the implementor intentionally changes that
-aspect of \eTeX's functionality: therefore \.{etex.sys} can modify the
-\\{banner} string in the same way as does \.{tex.ch}.
-
-Then, \.{etex.sys} might deviate from \.{tex.ch} in order to use a
-different pool file name and\slash or format file extension (see below).
-
-Finally, \.{etex.sys} will necessarily deviate whenever \.{etex.ch}
-and \.{tex.ch} try to change the same piece of \.{WEB} code or when the
-system-independent \eTeX\ changes from \.{etex.ch} and the
-system-dependent \TeX\ changes from \.{tex.ch} interfere in some other way.
-In case of any such interference implementors must first of all determine
-how to combine the respective changes from \.{etex.ch} and \.{tex.ch}
-in order to obtain \eTeX's functionality for a particular system.
-Obviously, this process cannot be automated since it requires human
-insight.
-
-The \NTS\ team has tried to formulate \.{etex.ch} such that
-interferences with system-dependent change files \.{tex.ch} are
-unlikely. Suggestions by implementors how any remaining such
-interferences could be avoided by a reformulation of \.{etex.ch} will
-be taken into serious consideration. Such interferences can be further
-reduced by reformulating the system-dependent change file \.{tex.ch} for
-\TeX, e.g.\ by reducing the range of change entries from entire modules
-to the pieces of code that are actually changed.
-
-Implementors might prefer to maintain the system-dependent change file
-\.{etex.sys} not as a physical file but as a hypothetical file defined
-through its deviation from \.{tex.ch}. If there are no interferences of
-the kind mentioned above, then the effect of applying the changes from
-the hypothetical \.{etex.sys} to the hypothetical \.{etex.web} can be
-achieved by applying 3 change files, one after the other, to \.{tex.web}
-(using some tool such as \.{TIE}, \.{PATCHWEB}, or \.{WEBMERGE}):
-$$
-\vcenter{\halign{#\hfil&\qquad\.{#}\hfil&\qquad#\hfil\cr
-0.&tex.web&system-independent \.{WEB} source for \TeX\cr
-1.&etex.ch&system-independent changes for \eTeX\cr
-2.&tex.ch&system-dependent changes for \TeX\cr
-3.&tex.ech&additional system-dependent changes for \eTeX\cr
-}}
-$$
-The third change file \.{tex.ech} will be rather short and contains just
-the differences between \.{etex.sys} and \.{tex.ch}. It is recommended
-that implementors try to remove all interferences between \.{etex.ch}
-and \.{tex.ch} and use this method to generate \eTeX.
-
-As with \TeX\ there are three versions of \eTeX: \.{e-INITEX},
-\.{e-VIRTEX}, and \.{e-TRIPTEX}. Depending on the implementation they
-will again be generated from the three slightly different versions of
-\.{tex.ch} or with different compiler options or they may be one and the
-same program used with different run time options.
-

-\section \eTeX\ modes.
-In order to ensure maximal compatibility with \TeX, \eTeX\ can run in
-either compatibility mode or extended mode. The possibility of this
-choice is, of course, an extended feature of \eTeX. Once \eTeX\ has
-chosen compatibility mode it is, however, a legitimate implementation of
-\TeX\ (assuming the \TeX\ implementation itself is legitimate). The
-only differences between \eTeX\ in compatibility mode and \TeX\ are
-those allowed by D.~E.~Knuth [2] between different implementations of
-\TeX.
-
-An \.{e-TRIP} test suite [3] defines the criteria by which a program can
-qualify to use the name `\eTeX'. Part of the \.{e-TRIP} test consists
-of the standard \.{TRIP} test for \.{e-TRIPTEX} in compatibility and
-extended mode.
-
-\eTeX\ can therefore be used instead of \TeX\ without the necessity to
-maintain both programs. For the case that both programs should
-nevertheless co-exist on a system, it might be a good idea to name the
-pool file for \eTeX\ \.{etex.pool} instead of \.{tex.pool} and to use
-an extension other than \.{.fmt}, e.g., \.{.efmt} for \eTeX\ format
-files. (Format files for \TeX\ and \eTeX\ are incompatible). All this
-will require additional changes in the file \.{tex.ech}.
-
-When \.{INITEX} or \.{VIRTEX} start, they inspect the first non-blank
-character from the command line or in response to the \.{**} prompt.
-This may be an \.{\&} immediately followed by the name of a format file
-to be loaded. Otherwise \.{VIRTEX} loads a default format, whereas
-\.{INITEX} starts without loading a format.
-
-When \.{e-INITEX} or \.{e-VIRTEX} start, they inspect the first
-non-blank character from the command line or in response to the \.{**}
-prompt. This may again be an \.{\&} immediately followed by the name of
-a format file to be loaded; otherwise \.{e-VIRTEX} loads a default
-format. For \.{e-INITEX} the first non-blank character may be an \.{*}
-immediately followed by what would normally be the input for \.{INITEX}
-(without intervening blanks). \.{e-INITEX} enters extended mode in
-response to the \.{*}, or compatibility mode otherwise. This mode is
-recorded in format files produced by \.{e-INITEX} and entered again when
-such a format is loaded (by either \.{e-INITEX} or \.{e-VIRTEX}).

-\section Introduction.
-The program \TeX82 by D.E.~Knuth is in the public domain, and its
-algorithms are published; he has done this since he does not want to
-discourage its use by placing proprietary restrictions on the software.
-However, he doesn't want faulty imitations to masquerade as \TeX\
-processors, since users want \TeX\ to produce identical results on
-different machines. He has copyrighted the programs so that he has some
-chance to forbid unauthorized copies; he explicitly authorizes copying
-of correct \TeX\ implementations, and not of incorrect ones! In order
-to determine, what is a correct implementation of \TeX, he has devised
-a test suite for \TeX, the \.{TRIP} test [1].
-
-The program \eTeX\ by `The \NTS\ Team' extends the capabilities of \TeX\
-by adding a relatively small amount (less than 10 per cent) of code; it
-is in the public domain, and its algorithms (beyond those of \TeX) are
-published. This report has been inspired by and is based on the
-\.{TRIP} manual. It describes the \.{e-TRIP} test, a test suite that
-allows one to determine whether what one has is a correct implementation
-of \eTeX.
-
-If somebody claims to have a correct implementation of \eTeX, we will
-not believe it until we see that the \.{e-TRIP} test is performed
-properly. We propose, in fact, that a program must meet two criteria
-before it can justifiably be called \eTeX: (1)~The person who wrote it
-must be happy with the way it works at his or her installation; and
-(2)~the program must produce the correct results from the \.{e-TRIP}
-test. Hence we are planning to do whatever we can to suppress any
-systems that call themselves \eTeX\ without meeting conditions (1)
-and~(2). We have copyrighted the program (1994,98 by The \NTS\ Team,
-1999-2004 by P.~Breitenlohner) so that we have some chance to forbid
-unauthorized copies; we explicitly authorize copying of correct \eTeX\
-implementations, and not of incorrect ones!
-
-The process of generating an \eTeX\ implementation for a particular
-system [2] is based on that of generating a \TeX\ implementation for the
-same system. Moreover, when \eTeX\ is used in compatibility mode, it is
-supposed to be 100 per cent compatible with \TeX. Thus a correct \eTeX\
-implementation, when running in compatibility mode, must pass the
-\.{TRIP} test. In fact, the first part of the \.{e-TRIP} test for a
-particular implementation of \eTeX\ consists in performing the standard
-\.{TRIP} test (a)~for \eTeX\ in compatibility mode and (b)~for \eTeX\ in
-extended mode. The deviations in the test output from step~(a) should,
-of course, be limited to those explicitly allowed by Knuth and described
-in Appendix~A, item~5 of the \.{TRIP} manual. Any additional deviations
-in the test output from step~(b) must be accounted for by \eTeX's
-additional algorithms and are described in detail in this report. Once
-an \eTeX\ implementation has passed these preliminary tests, it should be
-subjected to the second part of the \.{e-TRIP} test. There the extended
-features and algorithms of \eTeX\ are tested under normal circumstances
-as well as in situations a normal user would never dream of (in the
-spirit of the \.{TRIP} test).
-
-The remainder of this report consists of appendices, whose contents ought
-to be described briefly here:
-
-Appendix A explains in detail how to carry out the first part of the
-test of \eTeX, given copies of the files described in the \.{TRIP}
-manual.
-
-Appendix B explains how to carry out the \eTeX\ specific test, given
-copies of the files described in the other appendices.
-
-Appendix C is \.{eTRIP.TEX}, a fiendish test file for \eTeX.
-
-Appendix D is \.{eTRIP.PL}, the property-list description of a
-special font called \.{etrip}.
-
-Appendix E is \.{eTRIPIN.LOG}, a correct transcript file \.{eTRIP.LOG}
-that results if \.{e-TRIPTEX} is applied to \.{eTRIP.TEX}.
-This run of \.{e-TRIPTEX} also creates a binary format file called
-\.{eTRIP.FMT} (or similar).
-
-Appendix F is a correct transcript file \.{eTRIP.LOG} that results if
-\.{e-TRIPTEX} or any other version of \eTeX\ is applied to \.{eTRIP.TEX}
-with format \.{eTRIP.FMT}.
-
-Appendix G is \.{eTRIP.TYP}, the symbolic version of a correct output
-file \.{eTRIP.DVI} that was produced at the same time as the
-\.{eTRIP.LOG} file of Appendix~F.
-
-Appendix H is \.{eTRIP.OUT}, a short file written out and read in by
-\eTeX\ when it processes \.{eTRIP.TEX}.
-
-Appendix I is \.{eTRIP.FOT}, an abbreviated version of Appendix F that
-appears on the user's terminal during the run that produces
-\.{eTRIP.LOG}.

-\section Appendix A: How to test \eTeX\ (part 1).
-
-\item{0.} Let's assume that you have copies of the files \.{TRIP.TEX},
-\.{TRIP.PL}, \.{TRIPIN.LOG}, \.{TRIP.LOG}, \.{TRIP.TYP}, and
-\.{TRIP.FOT} as described in Appendices~B, C, D, E, F, and~G of the
-\.{TRIP} manual [1] (in a safe place so that these ``master'' files will
-not be clobbered). Furthermore, let's suppose that you have a working
-\.{WEB} system [3], and that you have working programs \.{PLtoTF} and
-\.{DVItype}, as described in the \TeX ware report [4]. Finally let's
-assume that you are able to generate \eTeX\ as described in [2].
-
-\item{1.} Use \.{PLtoTF} to convert \.{TRIP.PL} into \.{TRIP.TFM};
-install \.{TRIP.TFM} in the standard file area for \TeX\ font metric
-files (or set a suitable environment variable or similar such that these
-files will be found by the program).
-
-\item{2.} Generate \.{e-TRIPTEX}, a special version of \.{e-INITEX}.
-The parameters for \.{e-TRIPTEX} should agree with those for \.{TRIPTEX}
-(as described in [1]), except that you should set \\{pool\_size} to a
-value $\ge\minps$ and \\{max\_strings} to a value $\ge\minms$.
-
-\item{3.} Perform the \.{TRIP} test as described in Appendix~A,
-items~3--7 of [1], with \.{e-TRIPTEX} as prepared in step~2. The program
-will run in compatibility mode and should therefore be fully compatible
-with \.{TRIPTEX} as described in [1]; apart from the allowed differences
-listed in item~5, the test output should deviate from the master files in
-the following \eTeX-specific point (and only in this one):
-
-\itemitem{a)} The name and version by which the program announces itself
-will be different; the extension of the format file produced during the
-first \.{e-TRIPTEX} run may be different.
-
-\def\bs{{\char`\\}}
-\def\sp{{\char'40}}
-
-\item{4.} Perform steps 3--7 of the \.{TRIP} test once again with
-\.{e-TRIPTEX}. During the first run type `\.{*\bs input\sp trip}'
-instead of `\.{\bs input\sp trip}', as a consequence \.{e-TRIPTEX} will
-run in extended mode. During the second run type `\.{\&trip\sp\bs
-toksdef\bs tokens=0\sp\bs input\sp trip}' instead of `\.{\sp\&trip\sp\sp
-trip\sp}'. The test output should differ from that of step~3 above in
-the following respects (and only in these):
-
-\itemitem{a)} The date and\slash or time will naturally be different.
-
-\itemitem{b)} The message `\.{entering extended mode}' will appear on
-the terminal and in the \.{TRIP.LOG} files.
-
-\itemitem{c)} The input `\.{*\bs input trip}' instead of
-`\.{\bs input trip}' is recorded in the first \.{TRIP.LOG} file;
-similarly the input `\.{\&trip\sp\bs toksdef\bs tokens=0\sp\bs input\sp
-trip}' instead of `\.{\sp\&trip\sp\sp trip\sp}' is recorded in the
-second \.{TRIP.LOG} file.
-
-\itemitem{d)} The following 6 lines (the last of them blank) will be
-missing from the first \.{TRIP.LOG} file\verblines 6
-! Bad register code (256).
-l.29 ...{1} \toksdef\tokens=256
- \show\errorstopmode
-A register number must be between 0 and 255.
-I changed this one to zero.
-
-
-\itemitem{e)} The first \.{TRIP.LOG} file will report the dumping of
-\extramw~additional memory words.
-
-\itemitem{f)} If the date has changed, the number of string characters
-dumped by the first \.{e-TRIPTEX} run may vary by $\pm2$.
-
-\itemitem{g)} Both \.{e-TRIPTEX} runs report \extracs~additional
-multiletter control sequences (in the \.{TRIP.LOG} files).
-
-\itemitem{f)} The second \.{e-TRIPTEX} run reports the unfinished
-group(s) when the program terminates; there are three additional lines
-(the first of them blank) on the terminal and in the \.{TRIP.LOG}
-file\verblines 3
-
-### semi simple group (level 1) entered at line 429 (begingroup)
-### bottom level
-The second \.{TRIP.LOG} does not contain six lines\verblines 1
-{restoring \fam=-1}
-one line\verblines 1
-{restoring \displayindent=0.0pt}
-and one line\verblines 1
-{restoring current font=\ip}
-Ten lines displaying an \.{\bs hbox} contain the additional text
-`\.{, display}'.
-Finally the second \.{TRIP.LOG} reports the additional use of
-\extrabf~input buffer (\.{b}) and \extrasv~save (\.{s}) stack positions.
-

-\section Appendix B: How to test \eTeX\ (part 2).
-
-\item{5.} Assume that you have copies of the ``master'' files
-\.{eTRIP.TEX}, \.{eTRIP.PL}, \.{eTRIPIN.LOG}, \.{eTRIP.LOG},
-\.{eTRIP.TYP}, \.{eTRIP.OUT}, and \.{eTRIP.FOT}, as in Appendices C, D,
-E, F, G, H, and~I (again in a safe place).
-
-\item{6.} Use \.{PLtoTF} to convert \.{eTRIP.PL} into \.{eTRIP.TFM};
-install \.{eTRIP.TFM} in the standard file area for \TeX\ font metric
-files (or set a suitable environment variable or similar).
-
-\item{7.} Run \.{e-TRIPTEX}; in response to the `\.{**}' prompt, type
-`\.{*etrip}'. You should get an output file \.{eTRIP.LOG} that matches
-the file \.{eTRIPIN.LOG} (Appendix~E). Contrary to the analogous step
-in the \.{TRIP} test (steps~3 and~4 above) there should be no error
-messages; lines in the output saying ``Emergency stop'' would indicate
-that you have performed this test with a standard \TeX\ or with \eTeX\
-in compatibility mode.
-
-\item{8.} Run \.{e-TRIPTEX} again; this time type
-`\.{\&etrip{\char'40}etrip}'. You should get outputs \.{eTRIP.LOG},
-\.{eTRIP.DVI}, and \.{eTRIP.OUT}. Furthermore, your terminal should
-receive output that matches \.{eTRIP.FOT} (Appendix~I). Once again, the
-terminal will be getting no output during the middle part of this test.
-
-\item{9.} Compare the \.{eTRIP.LOG} file from step 8 with the ``master''
-\.{eTRIP.LOG} file of step~5. There should be no lines saying
-``Emergency stop'' (see above) or ``Bug in your e-TeX implementation'';
-there should be perfect agreement between these files except in the
-following respects:
-
-\itemitem{a)} The dates and possibly the file names will naturally be
-different.
-
-\itemitem{b)} Glue settings in the displays of \TeX\ boxes are subject
-to system-dependent rounding, so slight deviations are permissible.
-However, such deviations apply only to the `\.{glue set}' values that
-appear at the end of an \.{\char'134hbox} or \.{\char'134vbox} line; all
-other numbers should agree exactly, since they are computed with integer
-arithmetic in a prescribed system-independent manner.
-
-\itemitem{c)} The amount of space in kerns that are marked ``for
-accent'' are, similarly, subject to system-dependent rounding.
-
-\itemitem{d)} If you had different values for \\{stack\_size},
-\\{buf\_size}, etc., the corresponding capacity values will be different
-when they are printed out at the end.
-
-\itemitem{e)} Help messages may be different; indeed, the author of
-\TeX\ encourages non-English help messages in versions of \TeX\ for
-people who don't understand English as well as some other language.
-Similarly, \eTeX\ could well be used with non-English help messages.
-
-\itemitem{f)} The total number and length of strings at the end may well
-be different.
-
-\itemitem{g)} If your \eTeX\ uses a different memory allocation or
-packing scheme or \.{DVI} output logic, the memory usage statistics may
-change.
-
-\item{10.} Use \.{DVItype} to convert your file \.{eTRIP.DVI} to a file
-\.{eTRIP.TYP}. The following options should be set when using
-\.{DVItype}:
-$$\vbox{\halign{#\hfil&\hfil#\cr
-Output level = 2\cr
-Starting page = \.{*.*.*.*.*.*.*.*.*.*}\hskip-20pt\cr
-Number of pages = 1000000&(this is the default)\cr
-Resolution = 7227/100&(this is one point per pixel)\cr
-New magnification = 0&(this is the default)\cr}}$$
-The resulting file should agree with the master \.{eTRIP.TYP} file of
-step~5, except that some of the values might be a little off due to
-floating-point rounding discrepancies. Furthermore there may be
-differences between `\\{right}' and `\\w' and `\\x' commands, and
-between `\\{down}' and `\\y' and `\\z'; the key thing is that all
-characters and rules and \\{xxx}'s should be in almost the same
-positions as specified in Appendix~G. If you have set
-\\{dvi\_buf\_size} to 800, then your \.{DVI} file should be virtually
-identical to the one supplied.)
