+<dl>
+<dt>bug fixes</dt>
+<dd><ul>
+<li><p><code>\xintZapFirstSpaces</code> hence also <code>\xintZapSpaces</code> from package <strong>xinttools</strong> were buggy when used with an argument either empty or containing only space tokens.</p></li>
+<li><p><code>\xintiiexpr</code> did not strip leading zeroes, hence <code>\xinttheiiexpr 001+1\relax</code> did not obtain the expected result ...</p></li>
+<li><p><code>\xinttheexpr \xintiexpr 1.23\relax\relax</code> should have produced <code>1</code>, but it produced <code>1.23</code></p></li>
+<li><p>the catcode of <code>;</code> was not set at package launching time.</p></li>
+<li><p>the <code>\XINTinFloatPrd:csv</code> macro name had a typo, hence <code>prd</code> was non-functional in <code>\xintfloatexpr</code>.</p></li>
+</ul>
+</dd>
+<dt>breaking changes</dt>
+<dd><ul>
+<li><p>in <code>\xintiiexpr</code>, <code>/</code> does <em>rounded</em> division, rather than the Euclidean division (for positive arguments, this is truncated division). The new <code>//</code> operator does truncated division,</p></li>
+<li><p>the <code>:</code> operator for three-way branching is gone, replaced with <code>??</code>,</p></li>
+<li><p><code>1e(3+5)</code> is now illegal. The number parser identifies <code>e</code> and <code>E</code> in the same way it does for the decimal mark, earlier versions treated <code>e</code> as <code>E</code> rather as postfix operators,</p></li>
+<li><p>the <code>add</code> and <code>mul</code> have a new syntax, old syntax is with <code>`+`</code> and <code>`*`</code> (quotes mandatory), <code>sum</code> and <code>prd</code> are gone,</p></li>
+<li><p>no more special treatment for encountered brace pairs <code>{..}</code> by the number scanner, <code>a/b[N]</code> notation can be used without use of braces (the <code>N</code> will end up as is in a <code>\numexpr</code>, it is not parsed by the <code>\xintexpr</code>-ession scanner),</p></li>
+<li><p>although <code>&amp;</code> and <code>|</code> are still available as Boolean operators the use of <code>&amp;&amp;</code> and <code>||</code> is strongly recommended. The single letter operators might be assigned some other meaning in later releases (bitwise operations, perhaps). Do not use them.</p></li>
+</ul>
+</dd>
+</dl>
+<p>There are many novelties, most to be found in package <strong>xintexpr</strong>. But first the other changes.</p>
+<ul>
+<li><p>new package <strong>xintcore</strong> has been split off <strong>xint</strong>. It contains the core arithmetic macros. It is loaded by package <strong>bnumexpr</strong>,</p></li>
+<li><p>neither <strong>xint</strong> nor <strong>xintfrac</strong> load <strong>xinttools</strong>. Only <strong>xintexpr</strong> does,</p></li>
+<li><p>whenever some portion of code has been revised, often use has been made of the <code>\xint_dothis</code> and <code>\xint_orthat</code> pair of macros for expandably branching,</p></li>
+<li><p>these tiny helpful macros, and a few others are in package <strong>xintkernel</strong> which contains also the catcode and loading order management code, initially inspired by code found in Heiko Oberdiek's packages,</p></li>
+<li><p>the <code>\xintAdd</code> and <code>\xintSub</code> macros from package <strong>xintfrac</strong> check if one of the denominator is a multiple of the other, and only if this is not the case do they multiply the denominators. But systematic reduction would be too costly,</p></li>
+<li><p>this naturally will be also the case for the <code>+</code> and <code>-</code> operations in <code>\xintexpr</code>,</p></li>
+<li><p>new macros <code>\xintiiDivRound</code>, <code>\xintiiDivTrunc</code> and <code>\xintiiMod</code> for rounded and truncated division of big integers (now in <strong>xintcore</strong>), alongside the earlier <code>\xintiiQuo</code> and <code>\xintiiRem</code>,</p></li>
+<li><p>with <strong>xintfrac</strong> loaded, the <code>\xintNum</code> macro does <code>\xintTTrunc</code> (which is truncation to an integer, same as <code>\xintiTrunc {0}</code>),</p></li>
+<li><p>new macro <code>\xintMod</code> in <strong>xintfrac</strong> for modulo operation with fractional numbers,</p></li>
+<li><p><code>\xintiexpr</code>, <code>\xinttheiexpr</code> admit an optional argument within brackets <code>[d]</code>, they round the computation result (or results, if comma separated) to <code>d</code> digits after decimal mark, (the whole computation is done exactly, as in <code>xintexpr</code>),</p></li>
+<li><p><code>\xintfloatexpr</code>, <code>\xintthefloatexpr</code> similarly admit an optional argument which serves to keep only <code>d</code> digits of precision, getting rid of cumulated uncertainties in the last digits (the whole computation is done according to the precision set via <code>\xintDigits</code>),</p></li>
+<li><p><code>\xinttheexpr</code> and <code>\xintthefloatexpr</code> ''pretty-print'' if possible, the former removing unit denominator or <code>[0]</code> brackets, the latter avoiding scientific notation if decimal notation is practical,</p></li>
+<li><p>the <code>//</code> does truncated division and <code>/:</code> is the associated modulo,</p></li>
+<li><p>multi-character operators <code>&amp;&amp;</code>, <code>|</code>, <code>==</code>, <code>&lt;=</code>, <code>&gt;=</code>, <code>!=</code>, <code>**</code>,</p></li>
+<li><p>multi-letter infix binary words <code>'and'</code>, <code>'or'</code>, <code>'xor'</code>, <code>'mod'</code> (quotes mandatory),</p></li>
+<li><p>functions <code>even</code>, <code>odd</code>,</p></li>
+<li><p><code>\xintdefvar A3:=3.1415;</code> for variable definitions (non expandable, naturally), usable in subsequent expressions; variable names may contain letters, digits, underscores. They should not start with a digit, the <code>@</code> is reserved, and single lowercase and uppercase Latin letters are predefined to work as dummy variables (see next),</p></li>
+<li><p>generation of comma separated lists <code>a..b</code>, <code>a..[d]..b</code>,</p></li>
+<li><p>Python syntax-like list extractors <code>[list][n:]</code>, <code>[list][:n]</code>, <code>[list][a:b]</code> allowing negative indices, but no optional step argument, and <code>[list][n]</code> (<code>n=0</code> for the number of items in the list),</p></li>
+<li><p>functions <code>first</code>, <code>last</code>, <code>reversed</code>,</p></li>
+<li><p>itemwise operations on comma separated lists <code>a*[list]</code>, etc.., possible on both sides <code>a*[list]^b</code>, an obeying the same precedence rules as with numbers,</p></li>
+<li><p><code>add</code> and <code>mul</code> must use a dummy variable: <code>add(x(x+1)(x-1), x=-10..10)</code>,</p></li>
+<li><p>variable substitutions with <code>subs</code>: <code>subs(subs(add(x^2+y^2,x=1..y),y=t),t=20)</code>,</p></li>
+<li><p>sequence generation using <code>seq</code> with a dummy variable: <code>seq(x^3, x=-10..10)</code>,</p></li>
+<li><p>simple recursive lists with <code>rseq</code>, with <code>@</code> given the last value, <code>rseq(1;2@+1,i=1..10)</code>,</p></li>
+<li><p>higher recursion with <code>rrseq</code>, <code>@1</code>, <code>@2</code>, <code>@3</code>, <code>@4</code>, and <code>@@(n)</code> for earlier values, up to <code>n=K</code> where <code>K</code> is the number of terms of the initial stretch <code>rrseq(0,1;@1+@2,i=2..100)</code>,</p></li>
+<li><p>iteration with <code>iter</code> which is like <code>rrseq</code> but outputs only the last <code>K</code> terms, where <code>K</code> was the number of initial terms,</p></li>
+<li><p>inside <code>seq</code>, <code>rseq</code>, <code>rrseq</code>, <code>iter</code>, possibility to use <code>omit</code>, <code>abort</code> and <code>break</code> to control termination,</p></li>
+<li><p><code>n++</code> potentially infinite index generation for <code>seq</code>, <code>rseq</code>, <code>rrseq</code>, and <code>iter</code>, it is advised to use <code>abort</code> or <code>break(..)</code> at some point,</p></li>
+<li><p>the <code>add</code>, <code>mul</code>, <code>seq</code>, ... are nestable,</p></li>
+<li><p><code>\xintthecoords</code> converts a comma separated list of an even number of items to the format expected by the <code>TikZ</code> <code>coordinates</code> syntax,</p></li>
+<li><p>completely new version <code>\xintNewExpr</code>, <code>protect</code> function to handle external macros. Not all constructs are compatible with <code>\xintNewExpr</code>.</p></li>
+</ul>
+<h2 id="n-20140401"><code>1.09n (2014/04/01)</code></h2>
+<ul>
+<li><p>the user manual does not include by default the source code anymore: the <code>\NoSourceCode</code> toggle in file <code>xint.tex</code> has to be set to 0 before compilation to get source code inclusion.</p></li>
+<li><p>bug fix (<strong>xinttools</strong>) in <code>\XINT_nthelt_finish</code> (this bug was introduced in <code>1.09i</code> of <code>2013/12/18</code> and showed up when the index <code>N</code> was larger than the number of elements of the list).</p></li>
+</ul>
+<h2 id="m-20140226"><code>1.09m (2014/02/26)</code></h2>
+<ul>
+<li><p>new in <strong>xinttools</strong>: <code>\xintKeep</code> keeps the first <code>N</code> or last <code>N</code> elements of a list (sequence of braced items); <code>\xintTrim</code> cuts out either the first <code>N</code> or the last <code>N</code> elements from a list.</p></li>
+<li><p>new in <strong>xintcfrac</strong>: <code>\xintFGtoC</code> finds the initial partial quotients common to two numbers or fractions <code>f</code> and <code>g</code>; <code>\xintGGCFrac</code> is a clone of <code>\xintGCFrac</code> which however does not assume that the coefficients of the generalized continued fraction are numeric quantities. Some other minor changes.</p></li>
+</ul>
+<h2 id="kb-20140213"><code>1.09kb (2014/02/13)</code></h2>
+<ul>
+<li><p>bug fix (<strong>xintexpr</strong>): an aloof modification done by <code>1.09i</code> to <code>\xintNewExpr</code> had resulted in a spurious trailing space present in the outputs of all macros created by <code>\xintNewExpr</code>, making nesting of such macros impossible.</p></li>
+<li><p>bug fix (<strong>xinttools</strong>): <code>\xintBreakFor</code> and <code>\xintBreakForAndDo</code> were buggy when used in the last iteration of an <code>\xintFor</code> loop.</p></li>
+<li><p>bug fix (<strong>xinttools</strong>): <code>\xintSeq</code> from <code>1.09k</code> needed a <code>\chardef</code> which was missing from <code>xinttools.sty</code>, it was in <code>xint.sty</code>.</p></li>
+</ul>
+<h2 id="k-20140121"><code>1.09k (2014/01/21)</code></h2>
+<ul>
+<li><p>inside <code>\xintexpr..\relax</code> (and its variants) tacit multiplication is implied when a number or operand is followed directly with an opening parenthesis,</p></li>
+<li><p>the <code>&quot;</code> for denoting (arbitrarily big) hexadecimal numbers is recognized by <code>\xintexpr</code> and its variants (package <strong>xintbinhex</strong> is required); a fractional hexadecimal part introduced by a dot <code>.</code> is allowed.</p></li>
+<li><p>re-organization of the first sections of the user manual.</p></li>
+<li><p>bug fix (<strong>xinttools</strong>, <strong>xint</strong>, ...): forgotten catcode check of <code>&quot;</code> at loading time has been added.</p></li>
+</ul>
+<h2 id="j-20140109"><code>1.09j (2014/01/09)</code></h2>
+<ul>
+<li><p>(<strong>xint</strong>) the core division routines have been re-written for some (limited) efficiency gain, more pronounced for small divisors. As a result the <em>computation of one thousand digits of <span class="math"><em>π</em></span></em> is close to three times faster than with earlier releases.</p></li>
+<li><p>some various other small improvements, particularly in the power routines.</p></li>
+<li><p>(<strong>xintfrac</strong>) a new macro <code>\xintXTrunc</code> is designed to produce thousands or even tens of thousands of digits of the decimal expansion of a fraction. Although completely expandable it has its use limited to inside an <code>\edef</code>, <code>\write</code>, <code>\message</code>, . It can thus not be nested as argument to another package macro.</p></li>
+<li><p>(<strong>xintexpr</strong>) the tacit multiplication done in <code>\xintexpr..\relax</code> on encountering a count register or variable, or a <code>\numexpr</code>, while scanning a (decimal) number, is extended to the case of a sub <code>\xintexpr</code>-ession.</p></li>
+<li><p><code>\xintexpr</code> can now be used in an <code>\edef</code> with no <code>\xintthe</code> prefix; it will execute completely the computation, and the error message about a missing <code>\xintthe</code> will be inhibited. Previously, in the absence of <code>\xintthe</code>, expansion could only be a full one (with <code>\romannumeral-`0</code>), not a complete one (with <code>\edef</code>). Note that this differs from the behavior of the non-expandable <code>\numexpr</code>: <code>\the</code> or <code>\number</code> are needed not only to print but also to trigger the computation, whereas <code>\xintthe</code> is mandatory only for the printing step.</p></li>
+<li><p>the default behavior of <code>\xintAssign</code> is changed, it now does not do any further expansion beyond the initial full-expansion which provided the list of items to be assigned to macros.</p></li>
+<li><p>bug fix (<strong>xintfrac</strong>): <code>1.09i</code> did an unexplainable change to <code>\XINT_infloat_zero</code> which broke the floating point routines for vanishing operands =:(((</p></li>
+<li><p>bug fix: the <code>1.09i</code> <code>xint.ins</code> file produced a buggy <code>xint.tex</code> file.</p></li>
+</ul>
+<h2 id="i-20131218"><code>1.09i (2013/12/18)</code></h2>
+<ul>
+<li><p>(<strong>xintexpr</strong>) <code>\xintiiexpr</code> is a variant of <code>\xintexpr</code> which is optimized to deal only with (long) integers, <code>/</code> does a euclidean quotient.</p></li>
+<li><p><code>\xintnumexpr</code>, <code>\xintthenumexpr</code>, <code>\xintNewNumExpr</code> are renamed, respectively, <code>\xintiexpr</code>, <code>\xinttheiexpr</code>, <code>\xintNewIExpr</code>. The earlier denominations are kept but to be removed at some point.</p></li>
+<li><p>it is now possible within <code>\xintexpr...\relax</code> and its variants to use count, dimen, and skip registers or variables without explicit <code>\the/\number</code>: the parser inserts automatically <code>\number</code> and a tacit multiplication is implied when a register or variable immediately follows a number or fraction. Regarding dimensions and <code>\number</code>, see the further discussion in <em>Dimensions</em>.</p></li>
+<li><p>(<strong>xintfrac</strong>) new conditional <code>\xintifOne</code>; <code>\xintifTrueFalse</code> renamed to <code>\xintifTrueAelseB</code>; new macros <code>\xintTFrac</code> (<code>fractional part</code>, mapped to function <code>frac</code> in <code>\xintexpr</code>-essions), <code>\xintFloatE</code>.</p></li>
+<li><p>(<strong>xinttools</strong>) <code>\xintAssign</code> admits an optional argument to specify the expansion type to be used: <code>[]</code> (none, default), <code>[o]</code> (once), <code>[oo]</code> (twice), <code>[f]</code> (full), <code>[e]</code> (<code>\edef</code>),... to define the macros</p></li>
+<li><p><strong>xinttools</strong> defines <code>\odef</code>, <code>\oodef</code>, <code>\fdef</code> (if the names have already been assigned, it uses <code>\xintoodef</code> etc...). These tools are provided for the case one uses the package macros in a non-expandable context, particularly <code>\oodef</code> which expands twice the macro replacement text and is thus a faster alternative to <code>\edef</code> taking into account that the <strong>xint</strong> bundle macros expand already completely in only two steps. This can be significant when repeatedly making <code>\def</code>-initions expanding to hundreds of digits.</p></li>
+<li><p>some across the board slight efficiency improvement as a result of modifications of various types to <em>fork macros</em> and <em>branching conditionals</em> which are used internally.</p></li>
+<li><p>bug fix (<strong>xint</strong>): <code>\xintAND</code> and <code>\xintOR</code> inserted a space token in some cases and did not expand as promised in two steps <code>:-((</code> (bug dating back to <code>1.09a</code> I think; this bug was without consequences when using <code>&amp;</code> and <code>|</code> in <code>\xintexpr-essions</code>, it affected only the macro form).</p></li>
+<li><p>bug fix (<strong>xintcfrac</strong>): <code>\xintFtoCCv</code> still ended fractions with the <code>[0]</code>'s which were supposed to have been removed since release <code>1.09b</code>.</p></li>
+</ul>
+<h2 id="h-20131128"><code>1.09h (2013/11/28)</code></h2>
+<ul>
+<li><p>parts of the documentation have been re-written or re-organized, particularly the discussion of expansion issues and of input and output formats.</p></li>
+<li><p>the expansion types of macro arguments are documented in the margin of the macro descriptions, with conventions mainly taken over from those in the <code>LaTeX3</code> documentation.</p></li>
+<li><p>a dependency of <strong>xinttools</strong> on <strong>xint</strong> (inside <code>\xintSeq</code>) has been removed.</p></li>
+<li><p>(<strong>xintgcd</strong>) <code>\xintTypesetEuclideAlgorithm</code> and <code>\xintTypesetBezoutAlgorithm</code> have been slightly modified (regarding indentation).</p></li>
+<li><p>(<strong>xint</strong>) macros <code>xintiSum</code> and <code>xintiPrd</code> are renamed to <code>\xintiiSum</code> and <code>\xintiiPrd</code>.</p></li>
+<li><p>(<strong>xinttools</strong>) a count register used in <code>1.09g</code> in the <code>\xintFor</code> loops for parsing purposes has been removed and replaced by use of a <code>\numexpr</code>.</p></li>
+<li><p>the few uses of <code>\loop</code> have been replaced by <code>\xintloop/\xintiloop</code>.</p></li>
+<li><p>all macros of <strong>xinttools</strong> for which it makes sense are now declared <code>\long</code>.</p></li>
+</ul>
+<h2 id="g-20131122"><code>1.09g (2013/11/22)</code></h2>
+<ul>
+<li><p>a package <strong>xinttools</strong> is detached from <strong>xint</strong>, to make tools such as <code>\xintFor</code>, <code>\xintApplyUnbraced</code>, and <code>\xintiloop</code> available without the <strong>xint</strong> overhead.</p></li>
+<li><p>new expandable nestable loops <code>\xintloop</code> and <code>\xintiloop</code>.</p></li>
+<li><p>bugfix: <code>\xintFor</code> and <code>\xintFor*</code> do not modify anymore the value of <code>\count 255</code>.</p></li>
+</ul>
+<h2 id="f-20131104"><code>1.09f (2013/11/04)</code></h2>
+<ul>
+<li><p>(<strong>xint</strong>) new <code>\xintZapFirstSpaces</code>, <code>\xintZapLastSpaces</code>, <code>\xintZapSpaces</code>, <code>\xintZapSpacesB</code>, for expandably stripping away leading and/or ending spaces.</p></li>
+<li><p><code>\xintCSVtoList</code> by default uses <code>\xintZapSpacesB</code> to strip away spaces around commas (or at the start and end of the comma separated list).</p></li>
+<li><p>also the <code>\xintFor</code> loop will strip out all spaces around commas and at the start and the end of its list argument; and similarly for <code>\xintForpair</code>, <code>\xintForthree</code>, <code>\xintForfour</code>.</p></li>
+<li><p><code>\xintFor</code> <em>et al.</em> accept all macro parameters from <code>#1</code> to <code>#9</code>.</p></li>
+<li><p>for reasons of inner coherence some macros previously with one extra <code>i</code> in their names (e.g. <code>\xintiMON</code>) now have a doubled <code>ii</code> (<code>\xintiiMON</code>) to indicate that they skip the overhead of parsing their inputs via <code>\xintNum</code>. Macros with a <em>single</em> <code>i</code> such as <code>\xintiAdd</code> are those which maintain the non-<strong>xintfrac</strong> output format for big integers, but do parse their inputs via <code>\xintNum</code> (since release <code>1.09a</code>). They too may have doubled-<code>i</code> variants for matters of programming optimization when working only with (big) integers and not fractions or decimal numbers.</p></li>
+</ul>
+<h2 id="e-20131029"><code>1.09e (2013/10/29)</code></h2>

-The xint bundle
-Release 1.09n (2014/04/01). Documentation date: 2014/04/01
+    Source:  xint.dtx (v1.1, 2014/10/28)
+    Author:  Jean-Francois Burnol
+    Info:    Expandable operations on big integers, decimals, fractions
+    License: LPPL 1.3c or later
 
-Copyright (C) 2013-2014 by Jean-Francois Burnol
-License: LaTeX Project Public License 1.3c or later.
+This README is also available as README.pdf and README.html.
 
-Contents: Abstract, Installation, License.
+Change log is in CHANGES.pdf and CHANGES.html.
 
-Abstract
-========
 
-xinttools is loaded by xint (hence by all other packages of the
-bundle, too): it provides utilities of independent interest such as
-expandable and non-expandable loops.
 
-xint implements with expandable TEX macros additions, subtractions,
-multiplications, divisions and powers with arbitrarily long numbers.
+USAGE
 
-xintfrac extends the scope of xint to decimal numbers, to numbers in
-scientific notation and also to fractions with arbitrarily long such
-numerators and denominators separated by a forward slash.
 
-xintexpr extends xintfrac with an expandable parser 
-         \xintexpr . . . \relax
-of expressions involving arithmetic operations in infix notation on
-decimal numbers, fractions, numbers in scientific notation, with
-parentheses, factorial symbol, function names, comparison operators,
-logic operators, twofold and threefold way conditionals,
-sub-expressions, macros expanding to the previous items.
+With LaTeX
 
-Further modules:
+    \usepackage{xint}       % expandable arithmetic with big integers
+    \usepackage{xintfrac}   % decimal numbers, fractions, floats
+    \usepackage{xintexpr}   % expressions with infix operators
 
-xintbinhex is for conversions to and from binary and hexadecimal
-bases.
+Further packages: xintbinhex, xintgcd, xintseries and xintcfrac. All
+dependencies are handled automatically. For example xintexpr
+automatically loads xintfrac which itself loads xint. Package xintcore
+is the subset of xint providing only the five operations on big
+integers: \xintiiAdd, \xintiiMul, ... There is also xinttools which is a
+separate package providing, among others, expandable and non-expandable
+loops such as \xintFor.
 
-xintseries provides some basic functionality for computing in an
-expandable manner partial sums of series and power series with
-fractional coefficients.
 
-xintgcd implements the Euclidean algorithm and its typesetting.
+With TeX
 
-xintcfrac deals with the computation of continued fractions.
+One does for example:
+
+    \input xintexpr.sty\relax
+
+Again, all dependencies are handled automatically. The packages may be
+loaded in any catcode context such that letters, digits, \ and % have
+their standard catcodes.
+
+xintcore.sty and xinttools.sty both import xintkernel.sty which has the
+catcode handler and package identifier and defines a few utilities such
+as \oodef or \xint_dothis/\xint_orthat.
+
+
+
+INSTALLATION
+
+
+Method A: using the package manager of your TeX distribution
+
+xint is included in TeXLive (hence also MacTeX) and MikTeX.
+
+There can be a few days of delay between apparition of a new version on
+CTAN and availability via the distribution package manager.
+
+
+Method B: manual installation using xint.tds.zip and unzip
+
+Assumes a GNU/Linux-like system (or Mac OS X).
+
+1.  obtain xint.tds.zip from CTAN:
+    http://mirror.ctan.org/install/macros/generic/xint.tds.zip
+
+2.  cd to the download repertory and issue:
+
+        unzip xint.tds.zip -d <TEXMF>
+
+    where <TEXMF> is a suitable TDS-compliant destination repertory. For
+    example, with TeXLive:
+
+    -   Linux, standard access rights, hence sudo is needed,
+        installation into the "local" tree:
+
+            sudo unzip xint.tds.zip -d /usr/local/texlive/texmf-local
+            sudo texhash /usr/local/texlive/texmf-local
+
+    -   Mac OS X, installation into user home folder (no sudo needed,
+        and it is recommended to not have a ls-R file there, hence no
+        texhash):
+
+            unzip xint.tds.zip -d  ~/Library/texmf
+
+
+Method C: manual installation using Makefile and xint.dtx
+
+The Makefile automatizes rebuilding from xint.dtx all documentation
+files as well as xint.tds.zip. It is for GNU/Linux-like (inc. Mac OS X)
+systems, with a teTeX like installation such as TeXLive. Furthermore the
+Pandoc software is required.
+
+1.  obtain xint.dtx and Makefile from http://www.ctan.org/pkg/xint.
+
+2.  put them in an otherwise empty working repertory, run make or
+    equivalently make help for further instructions.
+
+
+Method D: installation starting with only xint.dtx
+
+Run "tex xint.dtx" or "etex xint.dtx" to extract from xint.dtx all
+packages as well as these files:
+
+README.md
+    the current README with Markdown formatting.
+
+CHANGES.md
+    the changes across successive releases.
+
+xint.tex
+
+    used to generate xint.pdf via "latex xint.tex" (thrice) then
+    "dvipdfmx xint.dvi". For successful compilation, packages newtxtt,
+    newtxmath, etoc, mathastext are needed. Inclusion of the source code
+    is off by default, but the toggle can be set in xint.tex.
+
+    It is also possible to compile xint.tex with pdflatex.
+
+    A third option is to generate xint.pdf via pdflatex xint.dtx. Source
+    code is then included by default.
+
+Makefile.mk
+    this is for UNIX-like systems. Note: this file is only produced with
+    "etex xint.dtx", not with "tex xint.dtx". Rename it to Makefile and
+    run make on the command line for further help.
+
+doHTMLs.sh and doPDFs.sh
+    these are scripts (for UNIX-like systems) which can be used to
+    convert the README.md and CHANGES.md to HTML and PDF formats. They
+    require Pandoc.
+
+pandoctpl.latex
+    a Pandoc template used by doPDFs.sh.
+
+Finishing the installation in a TDS hierarchy:
+
+-   move the style files to TDS:tex/generic/xint/
+
+-   xint.dtx goes to TDS:source/generic/xint/
+
+-   the documentation (xint.pdf, README.md,...) goes to
+    TDS:doc/generic/xint/
+
+Depending on the destination, it may then be necessary to refresh a
+filename database.

-Most macros, and all of those doing computations, work purely by
-expansion without assignments, and may thus be used almost everywhere
-in TeX. The packages may be used with any flavor of TeX supporting the
-e-TeX extensions. LaTeX users will use \usepackage and others \input
-to load the package components.
-
-Installation
-============
-
-A. Installation using xint.tds.zip:
------------------------------------
-
-obtain xint.tds.zip from CTAN:
-  http://mirror.ctan.org/install/macros/generic/xint.tds.zip
-
-cd to the download repertory and issue 
-  unzip xint.tds.zip -d <TEXMF>
-for example: (assuming standard access rights, so sudo needed)
-  sudo unzip xint.tds.zip -d /usr/local/texlive/texmf-local
-  sudo mktexlsr
- 
-On Mac OS X, installation into user home folder:
-  unzip xint.tds.zip -d  ~/Library/texmf
- 
-B. Installation after file extractions:
----------------------------------------
-
-obtain xint.dtx, xint.ins and the README from CTAN:
-   http://www.ctan.org/pkg/xint
-
-- "tex xint.ins" generates the style files
-(pre-existing files in the same repertory will be overwritten).
-
-- without xint.ins: "tex or latex or pdflatex or xelatex xint.dtx" 
-will also generate the style files (and xint.ins).
-
-xint.tex is also extracted, use it for the documentation:
-
-- with latex+dvipdfmx: latex xint.tex thrice then dvipdfmx xint.dvi
-Ignore dvipdfmx warnings, but if the pdf file has problems with fonts
-(possibly from an old dvipdfmx), use then rather pdflatex or xelatex.
-
-- with pdflatex or xelatex: run it directly thrice on xint.dtx, or run 
-it on xint.tex after having edited the suitable toggle therein.
-
-Whether compiling xint.tex or xint.dtx, the documentation is by default
-produced without inclusion of the source code. See instructions in the
-file xint.tex for changing this default.
- 
-Finishing the installation: (on first installation the destination
-repertories may need to be created)

+<pre><code>Source:  xint.dtx (v1.1, 2014/10/28)
+Author:  Jean-Francois Burnol
+Info:    Expandable operations on big integers, decimals, fractions
+License: LPPL 1.3c or later</code></pre>
+<p>This README is also available as README.pdf and README.html.</p>
+<p>Change log is in CHANGES.pdf and CHANGES.html.</p>
+<h1 id="usage">Usage</h1>
+<h2 id="with-latex">With LaTeX</h2>
+<pre><code>\usepackage{xint}       % expandable arithmetic with big integers
+\usepackage{xintfrac}   % decimal numbers, fractions, floats
+\usepackage{xintexpr}   % expressions with infix operators</code></pre>
+<p>Further packages: <code>xintbinhex</code>, <code>xintgcd</code>, <code>xintseries</code> and <code>xintcfrac</code>. All dependencies are handled automatically. For example <code>xintexpr</code> automatically loads <code>xintfrac</code> which itself loads <code>xint</code>. Package <code>xintcore</code> is the subset of <code>xint</code> providing only the five operations on big integers: <code>\xintiiAdd</code>, <code>\xintiiMul</code>, ... There is also <code>xinttools</code> which is a separate package providing, among others, expandable and non-expandable loops such as <code>\xintFor</code>.</p>
+<h2 id="with-tex">With TeX</h2>
+<p>One does for example:</p>
+<pre><code>\input xintexpr.sty\relax</code></pre>
+<p>Again, all dependencies are handled automatically. The packages may be loaded in any catcode context such that letters, digits, <code>\</code> and <code>%</code> have their standard catcodes.</p>
+<p><code>xintcore.sty</code> and <code>xinttools.sty</code> both import <code>xintkernel.sty</code> which has the catcode handler and package identifier and defines a few utilities such as <code>\oodef</code> or <code>\xint_dothis/\xint_orthat</code>.</p>
+<h1 id="installation">Installation</h1>
+<h2 id="method-a-using-the-package-manager-of-your-tex-distribution">Method A: using the package manager of your TeX distribution</h2>
+<p><code>xint</code> is included in <a href="http://tug.org/texlive/">TeXLive</a> (hence also <a href="http://tug.org/mactex/">MacTeX</a>) and <a href="http://www.miktex.org/">MikTeX</a>.</p>
+<p>There can be a few days of delay between apparition of a new version on <a href="http://www.ctan.org/pkg/xint">CTAN</a> and availability via the distribution package manager.</p>
+<h2 id="method-b-manual-installation-using-xint.tds.zip-and-unzip">Method B: manual installation using <code>xint.tds.zip</code> and <code>unzip</code></h2>
+<p>Assumes a GNU/Linux-like system (or Mac OS X).</p>
+<ol style="list-style-type: decimal">
+<li><p>obtain <code>xint.tds.zip</code> from CTAN: <a href="http://mirror.ctan.org/install/macros/generic/xint.tds.zip" class="uri">http://mirror.ctan.org/install/macros/generic/xint.tds.zip</a></p></li>
+<li><p>cd to the download repertory and issue:</p>
+<pre><code>unzip xint.tds.zip -d &lt;TEXMF&gt;</code></pre>
+<p>where <code>&lt;TEXMF&gt;</code> is a suitable TDS-compliant destination repertory. For example, with TeXLive:</p>
+<ul>
+<li><p>Linux, standard access rights, hence sudo is needed, installation into the &quot;local&quot; tree:</p>
+<pre><code>sudo unzip xint.tds.zip -d /usr/local/texlive/texmf-local
+sudo texhash /usr/local/texlive/texmf-local</code></pre></li>
+<li><p>Mac OS X, installation into user home folder (no sudo needed, and it is recommended to not have a ls-R file there, hence no texhash):</p>
+<pre><code>unzip xint.tds.zip -d  ~/Library/texmf</code></pre></li>
+</ul></li>
+</ol>
+<h2 id="method-c-manual-installation-using-makefile-and-xint.dtx">Method C: manual installation using <code>Makefile</code> and <code>xint.dtx</code></h2>
+<p>The Makefile automatizes rebuilding from <code>xint.dtx</code> all documentation files as well as <code>xint.tds.zip</code>. It is for GNU/Linux-like (inc. Mac OS X) systems, with a teTeX like installation such as TeXLive. Furthermore the <a href="http://johnmacfarlane.net/pandoc/">Pandoc</a> software is required.</p>
+<ol style="list-style-type: decimal">
+<li><p>obtain <code>xint.dtx</code> and <code>Makefile</code> from <a href="http://www.ctan.org/pkg/xint" class="uri">http://www.ctan.org/pkg/xint</a>.</p></li>
+<li><p>put them in an otherwise empty working repertory, run <code>make</code> or equivalently <code>make help</code> for further instructions.</p></li>
+</ol>
+<h2 id="method-d-installation-starting-with-only-xint.dtx">Method D: installation starting with only <code>xint.dtx</code></h2>
+<p>Run <code>&quot;tex xint.dtx&quot;</code> or <code>&quot;etex xint.dtx&quot;</code> to extract from <code>xint.dtx</code> all packages as well as these files:</p>
+<dl>
+<dt><code>README.md</code></dt>
+<dd>the current README with Markdown formatting.
+</dd>
+<dt><code>CHANGES.md</code></dt>
+<dd>the changes across successive releases.
+</dd>
+<dt><code>xint.tex</code></dt>
+<dd><p>used to generate <code>xint.pdf</code> via <code>&quot;latex xint.tex&quot;</code> (thrice) then <code>&quot;dvipdfmx xint.dvi&quot;</code>. For successful compilation, packages <code>newtxtt</code>, <code>newtxmath</code>, <code>etoc</code>, <code>mathastext</code> are needed. Inclusion of the source code is off by default, but the toggle can be set in <code>xint.tex</code>.</p>
+<p>It is also possible to compile <code>xint.tex</code> with <code>pdflatex</code>.</p>
+<p>A third option is to generate <code>xint.pdf</code> via <code>pdflatex xint.dtx</code>. Source code is then included by default.</p>
+</dd>
+<dt><code>Makefile.mk</code></dt>
+<dd>this is for UNIX-like systems. Note: this file is only produced with <code>&quot;etex xint.dtx&quot;</code>, not with <code>&quot;tex xint.dtx&quot;</code>. Rename it to <code>Makefile</code> and run <code>make</code> on the command line for further help.
+</dd>
+<dt><code>doHTMLs.sh</code> and <code>doPDFs.sh</code></dt>
+<dd>these are scripts (for UNIX-like systems) which can be used to convert the <code>README.md</code> and <code>CHANGES.md</code> to HTML and PDF formats. They require <a href="http://johnmacfarlane.net/pandoc/">Pandoc</a>.
+</dd>
+<dt><code>pandoctpl.latex</code></dt>
+<dd>a Pandoc template used by <code>doPDFs.sh</code>.
+</dd>
+</dl>
+<p>Finishing the installation in a TDS hierarchy:</p>
+<ul>
+<li><p>move the style files to <code>TDS:tex/generic/xint/</code></p></li>
+<li><p><code>xint.dtx</code> goes to <code>TDS:source/generic/xint/</code></p></li>
+<li><p>the documentation (xint.pdf, README.md,...) goes to <code>TDS:doc/generic/xint/</code></p></li>
+</ul>
+<p>Depending on the destination, it may then be necessary to refresh a filename database.</p>
