+****** e-pTeX build 110102 ******
+----------------------------------------------------------------------
+
+ This program, ``e-pTeX'', is development of e-TeX, and it has
+features of Japanese pTeX. Because of this, perhaps ``pe-TeX'' is
+better name for this software, but because of historical reasons,
+I decided to continue to use ``e-pTeX'' as the name of this software.
+(When I developed e-pTeX first, this is ``e-TeX extension of pTeX''.
+ And moreover, there was another ``peTeX'' (about 2007.12--2008.1,
+ abandoned by appearance of e-pTeX) by Akira Kakuto.)
+
+ In addition to features of pTeX, e-pTeX can use 256 math font
+families (this feature is realized by fam256.ch, based on Omega's
+source code). This extension developed in mind that pTeX usually use
+more two families than original TeX (`Mincho' and `Gothic').
+
+ e-pTeX is developed as the project in the course named ``Computing
+for Mathematicians II''(http://ks.ms.u-tokyo.ac.jp/ (in Japanese), 2007
+Winter), and it is licensed under modified BSD (same as pTeX, ptexenc).
+
+ Thanks to Noriyuki Abe, Akira Kakuto, Takuji Tanaka, Takayuki Yato,
+Yusuke Kuroki and others for many help.

+% This is a change file for e-pTeX.
+%
+% e-pTeX is developed by Hironori Kitagawa,
+% based on pTeX by Sadayuki Tanaka <sada-t@ascii.co.jp>,
+% Ken Nakano <ken-na@ascii.co.jp>, and ASCII Corporation.
+%
+% Thanks for:
+% Noriyuki Abe, Akira Kakuto, Takuji Tanaka, Takayuki Yato,
+% Yusuke Kuroki.
+%
+% In this TeX Live realisation
+% eptex.web is build from:
+% tex.web
+% + etexdir/etex.ch e-TeX changes
+% + etexdir/tex.ch0 glue
+% + tex.ch Web2C changes
+% + etexdir/tex.ech e-TeX+Web2C changes
+%
+% and eptex.ch from:
+% + eptexdir/etex.ch0 glue
+% + ptexdir/ptex-base.ch pTeX changes
+% + eptexdir/eptex.ech e-TeX+pTeX changes
+% + eptexdir/etex.ch1 glue
+% + eptexdir/fam256.ch borrowed from Omega
+% + eptexdir/pdfutils.ch borrowed from pdfTeX
+% + tex-binpool.ch compiled pool file
+%
+% where the three small files denoted as glue resolve incompatibilities
+% between the main change files (used to build TeX, e-TeX, and pTeX).

+\def\pdfTeX{pdf\TeX}
+
+This section is (almost) straight from MetaPost. I had to change
+the types (use |integer| instead of |fraction|), but that should
+not have any influence on the actual calculations (the original
+comments refer to quantities like |fraction_four| ($2^{30}$), and
+that is the same as the numeric representation of |maxdimen|).
+
+I've copied the low-level variables and routines that are needed, but
+only those (e.g. |m_log|), not the accompanying ones like |m_exp|. Most
+of the following low-level numeric routines are only needed within the
+calculation of |norm_rand|. I've been forced to rename |make_fraction|
+to |make_frac| because TeX already has a routine by that name with
+a wholly different function (it creates a |fraction_noad| for math
+typesetting) -- Taco
+
+And now let's complete our collection of numeric utility routines
+by considering random number generation.
+\MP\ generates pseudo-random numbers with the additive scheme recommended
+in Section 3.6 of {\sl The Art of Computer Programming}; however, the
+results are random fractions between 0 and |fraction_one-1|, inclusive.
+
+There's an auxiliary array |randoms| that contains 55 pseudo-random
+fractions. Using the recurrence $x_n=(x_{n-55}-x_{n-31})\bmod 2^{28}$,
+we generate batches of 55 new $x_n$'s at a time by calling |new_randoms|.
+The global variable |j_random| tells which element has most recently
+been consumed.
+
+@<Glob...@>=
+@!randoms:array[0..54] of integer; {the last 55 random values generated}
+@!j_random:0..54; {the number of unused |randoms|}
+@!random_seed:scaled; {the default random seed}
+
+@ A small bit of metafont is needed.

+@ The |make_frac| routine produces the |fraction| equivalent of
+|p/q|, given integers |p| and~|q|; it computes the integer
+$f=\lfloor2^{28}p/q+{1\over2}\rfloor$, when $p$ and $q$ are
+positive. If |p| and |q| are both of the same scaled type |t|,
+the ``type relation'' |make_frac(t,t)=fraction| is valid;
+and it's also possible to use the subroutine ``backwards,'' using
+the relation |make_frac(t,fraction)=t| between scaled types.
+
+If the result would have magnitude $2^{31}$ or more, |make_frac|
+sets |arith_error:=true|. Most of \MP's internal computations have
+been designed to avoid this sort of error.
+
+If this subroutine were programmed in assembly language on a typical
+machine, we could simply compute |(@t$2^{28}$@>*p)div q|, since a
+double-precision product can often be input to a fixed-point division
+instruction. But when we are restricted to \PASCAL\ arithmetic it
+is necessary either to resort to multiple-precision maneuvering
+or to use a simple but slow iteration. The multiple-precision technique
+would be about three times faster than the code adopted here, but it
+would be comparatively long and tricky, involving about sixteen
+additional multiplications and divisions.
+
+This operation is part of \MP's ``inner loop''; indeed, it will
+consume nearly 10\pct! of the running time (exclusive of input and output)
+if the code below is left unchanged. A machine-dependent recoding
+will therefore make \MP\ run faster. The present implementation
+is highly portable, but slow; it avoids multiplication and division
+except in the initial stage. System wizards should be careful to
+replace it with a routine that is guaranteed to produce identical
+results in all cases.
+@^system dependencies@>
+
+As noted below, a few more routines should also be replaced by machine-dependent
+code, for efficiency. But when a procedure is not part of the ``inner loop,''
+such changes aren't advisable; simplicity and robustness are
+preferable to trickery, unless the cost is too high.

+@ Of course \epTeX\ can produce a \.{DVI} file only, not a PDF file.
+A \.{DVI} file does not have the information of the page height,
+which is needed to implement \.{\\pdflastypos} correctly.
+To keep the information of the page height, I (H.~Kitagawa)
+adopted \.{\\pdfpageheight} primitive from pdf\TeX.
+
+In \pTeX (and \hbox{\epTeX}), the papersize special
+\.{\\special\{papersize=\<width>,\<height>\}} is commonly used
+for specifying page width/height.
+If \.{\\readpapersizespecial} is greater than~0, the papersize special also
+changes the value of \.{\\pdfpagewidth} and \.{\\pdfpageheight}.
+This process is done in the following routine.
+
+{\def\<#1>{\langle\hbox{#1\/}\rangle}
+In present implementation, the papersize special $\<special>$,
+which can be interpreted by this routine, is defined as follows.
+$$\eqalign{%
+ \<special> &\longrightarrow \.{papersize=}\<length>\.{,}\<length>\cr
+ \<length> &\longrightarrow \<decimal>
+ \<optional~\.{true}>\<physical unit>\cr
+ \<decimal> &\longrightarrow \.{.} \mid \<digit>\<decimal> \mid
+ \<decimal>\<digit>\cr
+}$$}
+Note that any space, ``\.{,}'' as a decimal separator, minus~symbol
+are neither permitted.
