* Introduction or "What's this all about?"
------------------------------------------
This document is for new and experienced users of literate programming
tools. The purpose is to explain the concept of literate programming and
to provide a resource for locating files of interest to literate
programmers and those interested in literate programming.
The Literate Programming (LitProg) Frequently Asked Questions (FAQ) list
is maintained by Dave Thompson, who can be reached at:
wqdbt@ttacs.ttu.edu * Preferred mailing address for FAQ
related comments/questions.
thompson@sun1.coe.ttu.edu * Read occasionally.
Comment and constructive criticism is welcome. Direct flames to
/dev/null (or > nul if you're a msdos user! ;-) If you find an error,
please report it. I'm particularly interested in establishing the
locations of generally available literate programming tools. If you are
the author of such a tool and wish to have it included in this list,
please send email.
Please note this is a work-in-progress. It is *not* complete, and
probably will not be complete for some months. Nevertheless, the
information contained herein may be useful to some. Use it as it is
intended.

* How do I get the FAQ?
-----------------------
- Literate Programming FAQ
--------------------------
You have many ways to get a current copy of this FAQ. One is to use
anonymous ftp (if you don't know how, see a later section in this FAQ)
to connect to one of the Comprehensive TeX Arvchive Network (CTAN) sites
or the Literate Programming Archive and retrieve a copy of the file.
Open an ftp connection to one of the CTAN sites and retrieve the file:
help/LitProg-FAQ
(For more information on CTAN and the literate programming archive, see
the section below entitled "Internet Nodes of Interest to Literate
Programmers.")
An alternative is to use the fileserver at Sam Houston State University
(SHSU). Send a message to FILESERV@SHSU.EDU and include in your
message:
SENDME LITPROG.FAQ
The file server will forward a copy of the file to you via email.
- ----------------------------------------------------------------------
- FWEB FAQ
----------
David Coker <coker@astro.sunyit.edu> now maintains the FWEB FAQ. (We
all owe Marcus Speh a big THANK YOU for maintaining the FWEB FAQ for so
long!) The current version number is 1.30a. It can be retrieved in the
same way as this FAQ; either by anonymous ftp or through the SHSU file
server. On the SHSU server, the file name is FAQ.FWEB. Invoke your ftp
software, open a connection to NIORD.SHSU.EDU [192.92.115.8], attach to
the directory FAQ, and transfer the file FAQ.FWEB.
Alternatively, send a message to the file server, FILESERV@SHSU.EDU, and
include the following text in a one line message:
SENDME FAQ.FWEB
The file server will send the current version of the file via email.
The FWEB FAQ exists in various formats, including HyperText (see other
resources below). In Europe, the complete distribution can also be
obtained from ftp.desy.de [131.169.10.115] in directory
/pub/faq/web/fweb/. It is also available from the literate programming
archive (LPA) in the directory LPA/Documentation/faq/fweb (see the
references to LPA below for more information).
= ======================================================================
* Is there a newsgroup?
-----------------------
One of the most important resources is the literate programming
newsgroup, comp.programming.literate. You can read this newsgroup using
your standard reader. Altenatively, the newsgroup is gated to a mailing
list hosted by George Greenwade and Sam Houston State University. You
can subscribe by sending mail to the list-server, LISTSERV@SHSU.EDU, and
include in the message one line of text:
SUBSCRIBE LITPROG "your name in quotes"
The list is unmoderated; messages sent to litprog@shsu.edu are
automatically distributed to all subscribers and cross-posted to
comp.programming.literate.
Archives of the mailing list and newsgroup are maintained on
niord.shsu.edu [192.92.115.8] in the directory litprog.
= ======================================================================
* What internet nodes are of interest to literate programmers?
--------------------------------------------------------------
The principal nodes of interest to literate programmers are the Literate
Programming Archive (LPA hereafter) and the CTAN (Comprehensive TeX
Archive Network).
The Literate Programming Archive (LPA) is:
Node: ftp.th-darmstadt.de [130.83.55.75]

* What is Literate Programming?
-------------------------------
Literate programming is the combination of documentation and source
together in a fashion suited for reading by human beings. In fact,
literate programs should be enjoyable reading, even inviting! (Sorry
Bob, I couldn't resist!) In general, literate programs combine source
and documentation in a single file. Literate programming tools then
parse the file to produce either readable documentation or compilable
source. The WEB style of literate programming was created by D.E. Knuth
during the development of his TeX typsetting software.
All the original work revolves around a particular literate programming
tool called WEB. Knuth says:
The philosophy behind WEB is that an experienced system
programmer, who wants to provide the best possible
documentation of his or her software products, needs two
things simultaneously: a language like TeX for formatting,
and a language like C for programming. Neither type of
language can provide the best documentation by itself; but
when both are appropriately combined, we obtain a system
that is much more useful than either language separately.
The structure of a software program may be thought of as a
web that is made up of many interconnected pieces. To
document such a program we want to explain each individual
part of the web and how it relates to its neighbours. The
typographic tools provided by TeX give us an opportunity to
explain the local structure of each part by making that
structure visible, and the programming tools provided by
languages such as C or Fortran make it possible for us to
specify the algorithms formally and unambigously. By
combining the two, we can develop a style of programming
that maximizes our ability to perceive the structure of a
complex piece of software, and at the same time the
documented programs can be mechanically translated into a
working software system that matches the documentation.
Another author (Eric W. van Ammers) wrote me a short article treating
his opinions on literate programming. The text follows:
First observation on LP
About 90% of the disussion on this list is about problems with
applying some WEB-family member to a particular programming language or
a special documentation situation. This is ridiculous, I think. Let me
explain shortly why...
Lemma 1:
I have proposed for many years that programming has nothing to do
with programming langauges, i.e. a good programmer makes good programs
in any language (given some time to learn the syntax) and a bad
programmer will never make a good program, no matter the language he
uses (today many people share this view, fortunately).
Lemma 2:
Literate Programming has (in a certain way not yet completely understood)
to do with essential aspects of programming.
Conclusion 1:
A LP-tool should be independent of programming language.
Lemma 3:
It seems likely that the so called BOOK FORMAT PARADIGM [ref. 1] plays an
important role in making literate programs work.
Lemma 4:
There are very many documentation systems currently being used to produce
documents in the BOOK FORMAT.
Conclusion 2:
A LP-tool should be independent of the documentation system that the
program author whishes to use.
My remark some time ago that we should discuss the generic properties of
an LP-tool was based on the above observation.
References:
[1] Paul W. Oman and Curtus Cook. Typographical style is more than cosmetic.
CACM 33, 5, 506-520 (May 1990)
Second observation on LP
The idea of a literate program as a text book should be extendend
even further. I would like to see a literate program as an (in)formal
argument of the correctness of the program.
Thus a literate program should be like a textbook on mathematicics.
A mathematical textbook explains a theory in terms of lemma and
theorems. But the proofs are never formal in the sense that they are
obtaind by symbol manipulation of a proof checker. Rather the proofs are
by so called "informal rigour", i.e. by very precise and unambiguous
sentences in a natural language.

==============================================================================
Another author (Norman Ramsey) wrote me and asked that his opinions be included
in the FAQ. What follows are Norman's comments verbatim.
I see it's time for the ``how is literate programming different from
verbose commenting'' question. Perhaps David Thompson will get this
into the FAQ. Alert! What follows are my opinions. In no way do I
claim to speak for the (fractious) literate-programming community.
How is literate programming different from verbose commenting?
There are three distinguishing characteristics. In order of
importance, they are:
- flexible order of elaboration
- automatic support for browsing
- typeset documentation, especially diagrams and mathematics
Flexible order of elaboration means being able to divide your source
program into chunks and write the chunks in any order, independent of
the order required by the compiler. In principle, you can choose the
order best suited to explaining what you are doing. More subtly, this
discipline encourages the author of a literate program to take the
time to consider each fragment of the program in its proper sphere,
e.g., not to rush past the error checking to get to the ``good
parts.'' In its time and season, each part of the program is a good
part. (This is the party line; your mileage may vary.)
I find the reordering most useful for encapsulating tasks like input
validation, error checking, and printing output fit for humans --- all
tasks that tend to obscure ``real work'' when left inline.
Reordering is less important when using languages like Modula-3, which
has exceptions and permits declarations in any order, than when using
languages like C, which has no exceptions and requires declaration
before use.
Automatic support for browsing means getting a table of contents,
index, and cross-reference of your program. Cross-reference might be
printed, so that you could consult an index to look up the definition
of an identifier `foo'. With good tools, you might get a printed
mini-index on every page if you wanted. Or if you can use a hypertext
technology, cross-reference might be as simple as clicking on an
identifier to reach its definition.
Indexing is typically done automatically or `semi-automatically', the
latter meaning that identifier definitions are marked by hand.
Diligently done semi-automatic indexes seem to be best, because the
author can mark only the identifiers he or she considers important,
but automatic indexing can be almost as good and requires no work.
Some tools allow a mix of the two strategies.
Some people have applied literate-programming tools to large batches
of legacy code just to get the table of contents, index, and
cross-reference.
I don't use diagrams and mathematics very often, but I wouldn't want
to have to live without them. I have worked on one or two projects
where the ability to use mathematical formulae to document the program
was indispensible. I also wouldn't like to explain some of my
concurrent programs without diagrams. Actually I write almost all of
my literate programs using only sections headers, lists, and the
occasional table.
>Wouldn't it be easier to do one's literate programming using a wysiwyg
>word processor (e.g. Word for Windows) and indicate what is source
>code by putting it in a different font?
The data formats used in wysiwyg products are proprietary, and they
tend to be documented badly if at all. They are subject to change at
the whim of the manufacturer. (I'll go out on a limb and say there
are no significant wysiwyg tools in the public domain. I hope the
Andrew people will forgive me.) These conditions make it nearly
impossible to write tools, especially tools that provide automatic
indexing and cross-reference support. The CLiP people have a partial
solution that works for tools that can export text --- they plant tags
and delimiters throughout the document that enable the reordering
transformation (``tangling'').
People use TeX, roff, and HTML because free implementations of these
tools are widely available on a variety of platforms. TeX and HTML
are well documented, and TeX and roff are stable. TeX is the most
portable. I think I have just answered the FAQ ``how come all these
tools use TeX, anyway?'' :-)
Norman Ramsey
As one final offering of opinion, I (David Thompson) find the following
observations by Kayvan Sylvan interesting. I found these in an old
email message while scanning my archives.
I've just read about 5 megabytes of litprog mail.
It's taken me a while to get back to LitProg, since work and family
matters got in the way.
With the perspective gained from reading 4 months of archives in a
couple of days, I have some thoughts to share. :-)
1. There's still too little sharing of real-world literate programs
and techniques.
I want to see more code being posted and more peer review going on.
I don't really know whether the literate Perl, Prolog, C, C++, or
Lisp code I write is good literate programming, because I haven't
gotten too many comments other than "Wow. Cool. Looks nice." I
suspect there are other literate programmers who are hungry for
constructive criticism of their publications and I think that the
LitProg mailinglist/newsgroup can be a forum for this.
2. Along the same lines as #1, I want to see a document that is a set
of style guidelines or useful suggestions for literate programming.
There has been talk along this line at various times, but no one
has stepped forward to coordinate this.
This document would answer general literate programming questions
like "How do I structure my C++ WEB to make the interface obvious
for users of the contained classes but still document the
implementation in a sensible way?" I'd be willing to collect bits
of advice and/or guidelines and compile it into a LitProg
suggestions document in my copious spare time.
It's good to be "back" (I never really went anywhere, but it feels
like I'm returning).
Happy New Year to all!!!

* How do I begin literate programming?
--------------------------------------
A recommended book is D.E. Knuth's collection of articles (1992)
"Literate Programming," Center for the Study of Language and
Information, Stanford University, ISBN 0-937073-80-6 (pbk). This book
gives insight into Knuth's thoughts as he developed the web system of
literate programming (and TeX for typesetting). It does not document
methods for literate programming.
A recommended book is Wayne Sewell's (1989) "Weaving a Program: Literate
Programming in WEB," Van Nostrand Reinhold, ISBN 0-442-31946-0 (pbk).
This book focuses on using Knuth's web system.
Some talk exists in the newsgroup/mailing list for a Usenet University
course in literate programming. I'm sure discussion of this topic will
be welcomed. If you are interested, please participate.
= ======================================================================
* What literate programming tools are available and where are they?
-------------------------------------------------------------------
A significant number of tools for literate programming are available.
Most have been ported from their original systems, so support multiple
computer platforms. If you are the developer of such a tool, and would
like to make the software freely available, please send me email and
I'll reply with a form (like those below) for you to fill in. (Or
short-circuit the process and kludge a form from below. :-)

Description:
CLiP does not use explicite commands to perform the extraction
process. Rather it recognizes pseudostatemens written as comments in
the programming language in question. CLiP distinguishes
pseudostatments from ordinary comments because the former comply with
a particular style. This style can be adjusted to suit virtually any
programming language. The CLiP approach to LP makes the system
extremely versatile. It is independent of programming language and
text processing environment.
We designed CLiP to be compatible with hypertext systems as well.
The idea is worked out in two HTML examples you can find on the net
through URL's
ftp://sun01.info.wau.nl/clip/html/pal1.htm
ftp://sun01.info.wau.nl/clip/html/queens.htm
Additional information (postscript format) is in
ftp://sun01.info.wau.nl:/clip/clip_*.ps
Features:
+ CLiP imposes virtually no limitations on the text-processing system
used to produce the documentation. If the text-processor supports
these items you can
+ structure the documentation according to your own taste.
+ include drawings, pictures, tables etc.
+ disclose your documentatio my means of X-ref tables, Indexes,
Table of contents, Table of tables, Table of figures, etc.
+ typeset the documented code.
+ Extracts any number of modules from a maximum of 64 source files.
+ No pretty-printing. Code from the source files is copied "as is" to
the module.
+ Appearance of code segments in the documentation matches those of
the modules to ease the identification of code segements.
+ Supports partially specified data types.
+ Comprehensive user manual (preliminary version) and technical
description.
- No automatic generation of a X-ref table for program identifiers.

advantage over something like Tex: formatting meta-information does not
clutter up your thinking.
fmweb allows you to write your code in a way that it looks exactly like
the WEB system's output from the outset. It supports output to multiple
files, is language independent, and doesn't care how many figures or
fonts you use.

FunnelWeb 3.0AC also supports HTML, and creates appropriate
hypertext links within the document among the code sections.
FunnelWeb 3.0AC also supports automatic and manual insertion of line
directives, so that compiler errors can be flagged back to the
original FunnelWeb source file. FunnelWeb 3.0AC is completely
compatible with FunnelWeb v3.0 sources (with one minor exception;
see the file README.ABC which comes with the FunnelWeb 3.0AC
distribution).

------
Developer: John A. Krommes <krommes@princeton.edu>
Version: 1.30a (1.40 for the experienced, patient, and brave)
Hardware: Unix, VMS, and DOS platforms (anything with ANSI C)
Languages: C, C++, Fortran-77, Fortran-90, Ratfor, TeX; also, a
language-independent mode.
Formatter: Plain TeX and LaTeX.
Availability: Anonymous ftp from:
ftp.pppl.gov:/pub/fweb
CTAN:/web/fweb
LPA:/fweb
DOS version in LPA:/machines/ms-dos
Readme: In bundle with above.
Description:
It also has a well-developed user's manual and its own FAQ (see
above). Beginning with 1.40, documentation is maintained in gnu
texinfo format. It runs on most platforms: VMS, PC, UNIX, and pretty
much anything that the GNU C compiler (GCC) is supported for.
Features:
+ Processes multiple languages during a single run (so one can mix C
and Fortran, for example).
+ Language-independent mode (v1.40).
+ Ability to turn off pretty-printing (v1.40).
+ Built-in Ratfor translator.
+ Built-in macro preprocessor (closely follows ANSI C, with
extensions).
+ A style file that allows the user to adjust many parameters and
behavior patterns of FWEB.
+ Various operator-overloading features that provide additional
pretty-printing capabilities to languages such as C++ and
Fortran-90.
+ Numerous miscellaneous features and command-line options.
Support: Bug reports and suggestions to krommes@princeton.edu
The following text was relayed by utcke@tu-harburg.d400.de recently. A
new entry for this FAQ will eventually be prepared.
NOTICE (June 12, 1995)
The 1.52 tar file was regenerated. If your version of that file included
the file web/defaults.mk, you should say `make clean' before beginning the
installation process, or use the new tar file.
NOTICE (June 10, 1995)
Version 1.52 is available. More bug fixes. 1.5x will remain in
beta-testing until about Sept. 1, 1995; further changes are hoped to be
minimal. If you have previously picked up 1.50 or 1.51, you definitely should
install 1.52 instead.
So it seems there's really 1.5x available for the experienced, patient
and brave --- especially given the following statement (same source):
Version 1.30, which for several years has been declared to be the stable
version of choice, is gradually getting out of date. I now recommend that
current users try VERY, VERY CAUTIOUSLY to upgrade to v1.50. Don't do that
the week before a critical deadline.

Those without ftp access can consult ``Literate Programming
Simplified,'' IEEE Software, September 1994, pp97-105.
Description:
noweb is designed to meet the needs of literate programmers while
retaining the simplest possible input format. Its primary
advantages are simplicity, extensibility, and language-independence.
noweb uses 5 control sequences to WEB's 27. The simple noweb manual is
only 2 pages; documenting the full power of noweave and notangle
requires another 3 pages. noweb works ``out of the box'' with any
programming language, and a simple back end for a new text formatter
can be written in about 50 lines of awk. The primary sacrifice
relative to WEB is the loss of prettyprinting.
noweb supports indexing and identifier cross-reference, including
hypertext ``hot links'' courtesy of Mosaic or Netscape. noweb
includes a simple, efficient LaTeX-to-HTML converter, so you can use
hypertext browsers on your legacy documents. noweb can also process
nuweb programs, so you can use noweb to convert a standard nuweb
program to HTML with one command.

Description:
A single program that takes a web file written in a combination of
latex and any programming language(s) and produces a latex file that
can be pretty printed and a set of files containing code for
compilation/interpretation by the appropriate language processors.
Strengths include speed, simplicity, multiple languages, nice indices
and cross-references, latex. Doesn't require any special macros or
macro files.
Drawbacks: latex-dependent, no code pretty printing, harder to make
indices than cweb.
More good stuff: nice support for make, doesn't reformat source files,
so they're easy to debug. Lots of control without too much effort.
That is, it doesn't do too much!
Future directions... Very little change planned, except perhaps
refinements in the indexing software.

Readme: Absent. Documentation is in the C source for c2latex.
Description:
C2latex provides simple support for literate programming in C. Given
a C source file in which the comments have been written in LaTeX,
c2latex converts the C source file into a LaTeX source file. It can
be used to produce typeset listings of C programs and/or documentation
associated with the program.
C2latex produces LaTeX source by implementing a small number of rules.
A C comment that starts at the beginning of a line is copied
unmodified into the LaTeX source file. Otherwise, non-blank lines are
surrounded by a pair of formatting commands (\begin{flushleft} and
\end{flushleft}), and the lines are separated by \\*. Each non-blank
line is formatted using LaTeX's \verb command, except comments within
the line are formatted in an \mbox.

description: c2man is an automatic documentation tool that extracts comments
from C source code to generate functional interface
documentation in the same format as sections 2 & 3 of the Unix
Programmer's Manual. It requires minimal effort from the
programmer by looking for comments in the usual places near the
objects they document, rather than imposing a rigid
function-comment syntax or requiring that the programmer learn
and use a typesetting language. Acceptable documentation can
often be generated from existing code with no modifications.
conformance: supports both K&R and ISO/ANSI C coding styles
features: + generates output in nroff -man, TeXinfo, LaTeX or HTML
format
+ handles comments as part of the language grammar
+ automagically documents enum parameter & return values
+ handles C (/* */) and C++ (//) style comments
- doesn't handle C++ grammar (yet)
requires: yacc/byacc/bison, lex/flex, and nroff/groff/texinfo/LaTeX.

Readme: In distribution
Description:
The idea behind the Fold2Web tool is the following: A programmer can
write his program source with a folding editor and later map the
folded source files automatically to WEB-files. The generated WEB-files
can then be modified by inserting required documentations.
The advantage by starting program developement with original sources is
to get short design cycles during the compile/debug steps. By using a
folding editor the global structuring information can be already
captured in folds during this developement phase. Fold information is
typically stored in comment lines and thus will not affect the
efficiency of the compile/debug design cycle.
Some folding editors and a folding mode for the emacs are available
(e.g. see our FUE folding editor for MSDOS machines which is a modified
micro emacs. Pick it at kirk in directory /pub/fold2web).
After reaching a stable version of a program source its time to convert
the source file to a WEB-file and do the program documentation.
Fold2Web is written to convert folded source text of any programming
language to nuweb files. The folded structure is kept by mapping folds
to scraps. Fold markers which differ between languages due to different
ways of specifying comments can be configured for each language.
Good results can also achived when given but poor documented program
sources have to be modified. Such sources can be folded using a folding
editor to extract the global structures. This offers a global view to
the program structures and help to understand its functionality.
Furthermore the program code is not affected, only comment lines are
inserted. Once folded the program source can be automatically
translated to a WEB document using the above tool.

Description:
This is a very simple mode I just hacked up. There's a lot wrong with
it, but I thought others may be interested, even as it stands. It
*requires* text properties, and assumes those used in GNU Emacs 19.22;
it'll quite likely work with Lucid Emacs, but I haven't tried it.
I use it with auctex8.1 and cc-mode 3.229, both of which are loaded
separately (I think my emacs is dumped with them, in fact).
The idea is to have one mode (which calls itself c-mode, but actually
has LaTeX-mode keybindings) generally (this means that the code is
hilighted nicely), and have the code chunks use a different keymap.

In the same directory is wm_refcard.tex which is an edited version of

The files limbo* are related to its use and notice that half them
have an uppercase L in them for LaTeX. The setup is based upon the
fact that we (I am not alone here) primarily use FWEB for C and Fortran
programming.
We are using version 1.40 of FWEB although John Krommes warns that it
is not mature and the manual is not yet updated. The info files are!
We are using LaTeX almost exclusively. That will likely change and we
will revert to version 1.30 if the final form of 1.40 cannot return
to the simple section numbers and avoid the HORRIBLE LATEX 0.1.7.2.4.6

The list is unmoderated; messages sent to info-tex@shsu.edu are
automatically distributed to all subscribers and cross-posted to
comp.text.tex.
Archives of the mailing list and newsgroup are maintained on
niord.shsu.edu [192.92.115.8] in the directory info-tex.
Another reason the TeX resources should be important is that so many of
the literate programming tools rely on either plain TeX or LaTeX as
their text formatter. (La)TeX software systems exist for most computing
platforms. These systems can be found on CTAN and other major archive
sites. Use archie to find them or simply ftp to one of the CTAN
sites and browse.

* Are there any code examples?
------------------------------
Examples of web programs are included with the FWEB, CWEB, and noweb
distributions. nuweb is written in itself.
Cameron Smith converted the K&R calculator program into a literate
program. It can be retrieved by anonymous ftp from:
niord.shsu.edu [192.92.115.8] directory kr-cweb-sample as
krcwsamp.zip
or from
LPA/Documentation
Ross Williams has released a funnelweb example. You can retrieve this
file from node ftp.adelaide.edu.au [129.127.40.3] as
/pub/funnelweb/examples/except.*
This file should be on CTAN as well.
Lee Wittenberg has posted a few litprog examples. They are available
via anonymous ftp from:
bart.kean.edu:/pub/leew/samples.LP
The Stanford GraphBase is a large collection of programs by Don Knuth for
doing all kinds of computations and games with graphs; it is written in
(Levy/Knuth) CWEB. More details in the distribution. It is available
via anonymous ftp from:
labrea.stanford.edu:/pub/sgb

* Bibliographies
----------------
Nelson Beebe has collected an extensive bibliography treating literate
programming. His work is available for anonymous ftp from
ftp.math.utah.edu [128.110.198.2] in directory /pub/tex/bib as files:
litprog.bib
litprog.ltx
litprog.twx.
Although I have not verified this, LPA is an alternate source for these
files. Note that they are updated frequently (Nelson says several times
each week), so be sure to get a fresh copy before extensive use.
Joachim Schrod indicates that these files may be updated daily and can
be retrieved via anonymous ftp at LPA/documentation.

* How to anonymously ftp
------------------------
Pretty much everything mentioned here is available by anonymous FTP.
FAQ lists cross-posted to news.answers and rec.answers can be gotten
from rtfm.mit.edu [18.181.0.24], under /pub/usenet/news.answers or under
/pub/usenet/more.specific.group.name
"anonymous FTP" is just a way for files to be stored where anyone
can retrieve them over the Net. For example, to retrieve the
latest version of the literate programming FAQ, do the following:
> ftp rtfm.mit.edu /* connect to the site; message follows */
> anonymous /* type this when it asks for your name */
> <your email address> /* type your address as the password */
> cd /pub/usenet /* go to the directory you want to be */
> cd comp.programming.literate /* one level down (no slash). */
> dir /* look at what's there */
> get literate-progamming-faq /* get the file; case-sensitive */
> quit /* stop this mysterious thing */
If your FTP program complains that it doesn't know where the site you
want to use is, type the numerical address instead of the sitename:
> ftp 18.181.0.24 /* connect with numerical address */
If you don't have ftp access, send e-mail to mail-server@rtfm.mit.edu
with the single word "help" in the body of the message.
Getting binary files (executables, or any compressed files) is only
slightly more difficult. You need to set binary mode inside FTP before
you transfer the file.
> binary /* set binary transfer mode */
> ascii /* set back to text transfer mode */
FAQs and spoiler lists are generally ascii files; everything else is
generally binary files.
Some common extensions on binary files in archive sites are:
.Z Compressed; extract with uncompress
.tar.Z Compressed 'tape archive'; uncompress then untar or tar -xvf
.gz or .z Gnu gzip; use gunzip (available from prep.gnu.ai.mit.edu)
.sit (Mac) StufIt archive
.zip Extract with Zip or Unzip
.zoo Yet another archive/compress program
.lhe (Amiga) ?
.lzh Lha archive program.
.arj (PC) Arj archive program.
.exe (PC) Sometimes self-extracting archives-just execute them.
.uue or .UUE Transfer as text file; use uudecode to convert to binary
.hqx (Mac) BinHex format; transfer in text mode
Generic help can be found in the FAQs of comp.binaries.<your_system_type>
for how to transfer, extract, and virus-check binary files. (At
rtfm.mit.edu)
If you can't FTP from your site, use one of the following ftp-by-mail
servers:
ftpmail@decwrl.dec.com
ftpmail@src.doc.ic.ac.uk
ftpmail@cs.uow.edu.au
ftpmail@grasp.insa-lyon.fr
For complete instructions, send a message reading "help" to the server.
If you don't know exactly what you're looking for, or exactly where it
is, there are programs and servers that can help you. For more info,
send e-mail to mail-server@rtfm.mit.with with the body of the
message reading send usenet/news.answers/finding-sources
Thanks to Aliza R. Panitz (the "buglady") for this text. I copied it
verbatim from her post on faq-maintainers with only minor modifications.

* Acknowledgements
------------------
This document would not have happened without the help of many people.
Among them are Marcus Speh, George Greenwade, Rob Beezer, Joachim
Schrod, Piet van Oostrum, and Ross N. Williams. A special thanks to
Aliza R. Panitz for the text describing how to execute an anonymous ftp
for files of interest.
Any omissions from these acknowledgements should be considered an act of
stupidity on my part. Of course, the authors of literate programming
tools mentioned above all play a vital role in the vitality of literate
programming. Furthermore, participants in the comp.programming.literate
newsgroup (and associated mailing list) all contributed in various
fashions. Thank all of you.
= ======================================================================
* End notes
-----------
This document will continue to evolve. I'm planning on adding entries
for additional literate programming tools and will expand the sections
on examples as more examples become available. Tools I will include are
WEB (the original pascal version) for starters. Others will be added as
I find and document them. Omission of a particular tool should not be
considered a snub in any sense--simply an error or oversight on my part.
