+Usage
+-----
+
+The package `bnumexpr` allows _expandable_ computations with big
+integers and the four infix operators `+`, `-`, `*`, `/` (which does
+rounded integer division) familiar from the `\numexpr` e-TeX parser.
+
+Besides extending the scope to arbitrarily big numbers (and having a
+more complete syntax, for example `-(1)` is legal input), it adds the
+truncated division operator `//`, and its associated modulo `/:`, the
+power operator `^` (or equivalently `**`), and the factorial post-fix
+operator `!`. The space character as well as the underscore character
+`_` both may serve to optionally separate digits in long numbers, for
+better readability of the input.
+
+For example:
+
+ \thebnumexpr ( 92_874_927_979^5 - 31_9792_7979^6 ) / 30!\relax
+
+expands (in two steps) to `-4006240736596543944035189`.
+
+The `\relax` ending token is mandatory and will be removed as a
+result of the evaluation.
+
+The expression parser is scaled-down from the `\xinttheiiexpr...\relax`
+parser as provided by package xintexpr[^1]: it does not handle boolean
+operators, dummy or user defined variables, functions, etc...
+
+By default the underlying arithmetic macros are the ones provided
+by package xintcore[^1] (its release 1.2 is required).
+
+bnumexpr has only one option _custom_ which says to not load
+xintcore, and a command `\bnumexprsetup` to inform the package
+which macros to use if not those from xintcore.
+
+Notice that the possibility not to use the xintcore macros might be
+removed in the future: perhaps a future release will maintain during
+computations a private internal representation (especially taylored
+either for the xintcore macros or new ones which would be included
+within `bnumexpr.sty` itself) and the constraints this implies may
+render optional use of other macros impossible.
+
+[^1]: <http://www.ctan.org/pkg/xint>
+
+Installation
+------------
+
+Obtain `bnumexpr.dtx` (and possibly, `bnumexpr.ins` and the `README`)
+from CTAN:
+
+> <http://www.ctan.org/pkg/bnumexpr>
+
+Both `"tex bnumexpr.ins"` and `"tex bnumexpr.dtx"` extract from
+`bnumexpr.dtx` the following files:
+
+`bnumexpr.sty`
+ : this is the style file.
+
+`README.md`
+ : reconstitutes this README.
+
+`bnumexprchanges.tex`
+ : lists changes from the initial version.
+
+`bnumexpr.tex`
+ : can be used to generate the documentation:
+
+ : - with latex+dvipdfmx: `"latex bnumexpr.tex"` (thrice) then
+ `"dvipdfmx bnumexpr.dvi"`.
+
+ : Ignore dvipdfmx warnings, but if the pdf file has problems with
+ fonts (possibly from an old dvipdfmx), use then rather pdflatex.
+
+ : - with pdflatex: `"pdflatex bnumexpr.tex"` (thrice).
+
+ : In both cases files `README.md` and `bnumexprchanges.tex` must
+ be present in the same repertory.
+
+without `bnumexpr.tex`:
+ : `"pdflatex bnumexpr.dtx"` (thrice) extracts all files and
+ simultaneously generates the pdf documentation.
+
+Finishing the installation:
+
+ bnumexpr.sty --> TDS:tex/latex/bnumexpr/
+
+ bnumexpr.dtx --> TDS:source/latex/bnumexpr/
+ bnumexpr.ins --> TDS:source/latex/bnumexpr/
+
+ bnumexpr.pdf --> TDS:doc/latex/bnumexpr/
+ README --> TDS:doc/latex/bnumexpr/
+
+Files `bnumexpr.tex`, `bnumexprchanges.tex`, `README.md` may be
+discarded.

+Anyhow, computations with thousands of digits take time, and this is probably
+a more stringent constraint.
-If the same expression needs to be evaluated again and again tens of
-thousands of times, it may be necessary to drop use of \bnumname and
-either use directly the macros from package \xintcorename, or apply
-|\xintNewIIExpr| from package \xintexprname to first construct the
-possibly very complicated nested macro.
+If the same operations need to be repeated again and again tens of thousands
+of times on varying (big) numbers, the memory problem mentioned above may be
+avoided by using nested macros rather than |\bnumexpr| or |\xintexpr|
+expressions. Utility |\xintNewIIExpr| from package \xintexprname can be used
+to construct the possibly very complicated nested macro from a given
+expression with the needed operators and usual {\catcode`# 12 |#1, #2, #3,
+ ...|} placeholders.
