+Packaging LyX 1.3.6 for Windows
+===============================
+
+Preparing the way
+=================
+
+The very first thing to do on the way to creating a LyX/Win package is
+to build the sources and install them somewhere accessible. (I've been
+using PREFIX='/J/Programs/LyX'.)
+
+Thereafter, the contents of this tree must be manipulated a
+little. I've written a little script, package_lyxwin.sh, to automate
+the process:
+
+* Copy the DLLs qt-mt3.dll, libiconv-2.dll, mingwm10.dll to the
+ $PREFIX/bin/ directory. These are needed by the LyX executable.
+
+* Strip the binaries in $PREFIX/bin/ of all debugging info.
+
+* Copy dt2dv.exe and dv2dt.exe to $PREFIX/bin/ and clean_dvi.py to
+ $PREFIX/Resources/lyx/scripts/ These are needed to enable dvips, yap
+ et al. to cope with "file names with spaces".
+
+* Add formats and converters to the $PREFIX/Resources/lyx/configure
+ script so that users can use the clean_dvi script transparently.
+
+* Remove all stuff generated by running configure. It makes sense on
+ your machine only, not for whoever is installing LyX. Specifically
+
+ xfonts/fonts.dir, xfonts/fonts.scale, doc/LaTeXConfig.lyx,
+ lyxrc.defaults, packages.lst and textclass.lst
+
+ should all be removed.
+
+Creating the LyX icons
+======================
+
+All icons are to be found in sub-directory icons/.
+
+The LyX icons, lyx_32x32.ico and lyx_doc_32x32.ico, are based on .svg
+files written and realease into the public domain by Andy Fitzsimon:
+
+http://openclipart.org/clipart/computer/icons/etiquette-theme/aps/LyX.svg
+http://openclipart.org/clipart/computer/icons/etiquette-theme/mimetype.svg
+
+lyx.svg is Andy's original.
+lyx_doc.svg is a merger of LyX.svg with mimetype.svg
+
+Working on a linux box, I used sodipodi (http://www.sodipodi.com/) to
+create the .svg file and to export these vector graphics images to
+32x32 pixel bitmaps (.png format). Thereafter I used gimp
+(http://www.gimp.org/) to generate reduced color depth versions (16,
+256 colors).
+
+Finally, on a WindowsXP machine, I used IconXP
+(http://www.aha-soft.com/iconxp/) to build the .ico files from these
+.png files at differing resolutions.
+
+Adding the LyX icons to lyx.exe
+===============================
+
+********************************************************************
+NOTE: Run 'strip' on lyx.exe before adding any images to it. 'strip'
+will not work after images have been added.
+
+$ strip lyx.exe
+j:\mingw\bin\strip.exe: lyx.exe: File in wrong format
+********************************************************************
+
+Windows executables can store various "resources", including images. I
+used ResourceHacker (http://rpi.net.au/~ajohnson/resourcehacker) to
+add the LyX icons to the .exe file.
+
+Fire up ResHacker.exe and load lyx.exe
+File>Open... lyx.exe
+
+Action>Add a new Resource...
+Open file with resource ... lyx_32x32.ico
+ Resource Type will be set to "ICONGROUP"
+Set Resource Name to "1". (No inverted commas.)
+Add Resource
+
+The icon will be shown in the main Resource Hacker window under
+Icon Group>1>0 and as Icon>5[0-3].
+
+Repeat for lyx_doc_32x32.ico, setting the Resource Name to "2".
+
+Save the modified lyx.exe. Resource Hacker will copy the original to
+lyx_original.exe. Remove it.
+
+Building the LyX installer
+==========================
+
+At this point my J:\Programs\LyX tree now contains everything that is
+to be released as a LyX/Win package. All that remains to do is to
+generate a Windows installer for it. I've written a script for NSIS
+(http://nsis.sourceforge.net/) to compile into an installer.
+
+You'll need to compile and install lyx_path_prefix.dll. From the
+comments in lyx_path_prefix.C:
+
+/* Compile the code with
+ *
+ * g++ -I/c/Program\ Files/NSIS/Contrib -Wall -shared \
+ * lyx_path_prefix.c -o lyx_path_prefix.dll
+ *
+ * Move resulting .dll to /c/Program\ Files/NSIS/Plugins
+ */
+
+Thereafter, you'll be able to build the installer itself:
+
+$ <PATH to>/makensis lyx_installer.nsi
+
+creating lyx_setup_136.exe ready to ship.

+README for DTL package - Thu 9 March 1995
+-----------------------------------------
+Author: Geoffrey Tobin <G.Tobin@ee.latrobe.edu.au>
+Version: 0.6.1
+CTAN Archive-path: dviware/dtl
+Brief Description:
+ DTL (DVI Text Language) files are equivalent to TeX's DVI files,
+ but are humanly readable, instead of binary. Two programs are
+ provided to translate between DVI and DTL: dv2dt, dt2dv.
+ dt2dv warns if byte addresses or string lengths recorded in a DTL
+ file are incorrect, then overrides them. This makes DTL files
+ editable. It also allows quoted apostrophes (\') and quoted quotes
+ (\\) in strings. The current DTL variety, sequences-6, separates
+ font paths into directory and font, which makes them freely editable.
+ In this release, DTL line numbers are correctly calculated, and three
+ memory leaks have been fixed.
+Keywords: dvi, TeX
+Includes:
+ Makefile README dt2dv.c dtl.h dv2dt.c
+ man2ps dtl.doc dvi.doc dt2dv.man dv2dt.man
+ hello.tex example.tex tripvdu.tex edited.txt
+
+Motivation:
+
+ When TeX has typeset a document, it writes its handiwork to a DVI
+file, for DVI processing software (such as viewers, printer drivers,
+dvidvi, and dvicopy) to read.
+
+The file dvi.doc lists the DVI file commands, with their opcodes
+(byte values), nominal command names, arguments, and meanings. For a
+detailed description of DVI file structure, see one of these:
+1. Donald E. Knuth's book _TeX: The Program_;
+2. The file tex.web, which contains source and documentation for TeX:
+ CTAN: systems/knuth/tex/tex.web
+3. The source for Knuth's dvitype program:
+ CTAN: systems/knuth/texware/dvitype.web
+4. Joachim Schrod's DVI drivers standard document, the relevant part
+ of which is at
+ CTAN: dviware/driv-standard/level-0
+
+Sometimes human beings are interested to see exactly what TeX has
+produced, for example when viewing or printing of the DVI file gives
+unexpected results. However, a DVI file is a compact binary
+representation, so we need software to display its contents.
+
+Binary file editors, when available, can show the DVI bytes, but not
+their meanings, except for the portions that represent embedded text.
+In particular, the command names are not shown, and the command
+boundaries are not respected.
+
+By contrast, Knuth's dvitype program is designed as an example of a
+DVI driver. However, dvitype is inconvenient for studying the DVI
+file alone, for the following reasons:
+1. Being a DVI driver, dvitype endeavors to read the TFM font metric
+files referenced in the DVI file. If a TFM file is absent, dvitype
+quits with an error message.
+2. When it starts, it prompts the user interactively for each of a
+series of options.
+3. Even the least verbose option gives masses of information that is
+not contained in the DVI file, coming instead from a combination of
+the data in the DVI file and TFM files.
+4. It does NOT show the DVI information in a way that accurately
+reflects the structure of the DVI file.
+5. Its output, if redirected to a file, produces a very large file.
+6. There is no automated procedure for converting the output of
+dvitype back to a DVI file, and doing it by hand is totally
+unreasonable.
+
+The first disadvantage is a killer if a TFM file is absent.
+Disadvantages two to four make dvitype very inconvenient for studying
+a DVI file. The fifth problem makes dvitype's output tedious,
+disk-hungry (so one deletes it almost immediately), and unsuitable for
+file transfer.
+
+The sixth disadvantage of dvitype is important to those people who are
+interested in editing DVI files. Since the DVI files refer explicitly
+to their own internal byte addresses, it's very easy to mess up a DVI
+file if one were to try to edit it directly, even apart from the problem
+of how to recognise a command.
+
+So an exact, concise, textual representation of a DVI file is needed,
+but dvitype does not produce one.
+
+Resolution:
+
+ Therefore, working from Joachim Schrod's description, I designed DTL
+and its conversion programs dv2dt (DVI -> DTL) and dt2dv (DTL -> DVI),
+which are provided as C sources:
+
+ dtl.h
+ dv2dt.c
+ dt2dv.c
+
+Although I was motivated by the TFM <-> PL conversion provided by
+Knuth's tftopl and pltotf programs, I deliberately designed DTL to be
+a much more concise and literal translation than the `property list'
+structure exemplified by PL. The result is that a DTL file is
+typically three times the size of its equivalent DVI file. The
+document dtl.doc lists the correspondence between the DTL command
+names and the (nominal) DVI command names.
+
+A clear advantage of an exact two-way conversion is that we can check
+(and prove) whether the converters worked truly on a given DVI file.
+The provided plain TeX files:
+ example.tex
+ tripvdu.tex
+can be used to test whether the compiled programs are behaving
+sensibly. Whereas example.tex is a simple document that uses a
+variety of plain TeX commands, tripvdu.tex provides a kind of
+`trip test' for DVI processor programs. Both documents are taken,
+with permission, from Andrew K. Trevorrow's dvitovdu (alias dvi2vdu)
+distribution (and are also part of the dvgt viewer distribution).
+
+The Makefile might have to be edited for your site, as it assumes
+gcc for your C compiler. Makefile compiles dv2dt and dt2dv, then
+runs tex on example.tex and tripvdu.tex, and also converts the
+resulting DVI files to DTL files, back to DVI files (with a change
+of name), then back again to DTL files, so that the results can be
+compared using a textual differencing program. (Many computer systems
+have such a program; on unix, as assumed by Makefile, this is named
+`diff'; ms-dos has one named `comp'.) This should produce a
+zero-length .dif file for each document, proving that the two DTL
+files are identical.
+
+A keen tester might also use a binary difference program on the DVI
+files, to check that they are identical, as they need to be. (On unix
+systems, the `diff' program suffices for that purpose.)
+
+Note:
+
+ In representing numeric quantities, I have mainly opted to use
+decimal notation, as this is how most of us are trained to think.
+However, for the checksums in the `fd' (font definition) commands, I
+chose octal notation, as this is used for checksums in Knuth's PL
+files, against which DVI files must be compared when a DVI driver
+loads a font.
+
+Caveat:
+
+The length of DTL commands is limited by the size of the line buffer
+in dt2dv.c.

+.SH DESCRIPTION
+.B dt2dv
+converts a text representation of a \*(Te\& DVI
+file, usually produced by the companion
+.BR dv2dt (1)
+utility, back to a binary DVI file. DTL
+.RI ( "DVI Text Language" )
+files can be edited, with care, and then restored
+to DVI form for processing by any \*(Te\& DVI
+driver program. In DTL files, font directory names
+and font names are preceded by a length field,
+which must be updated if the names are modified.
+.PP
+.BR dvitype (1)
+can also display a textual representation of DVI
+files, but in some implementations at least, it
+cannot be used in batch mode, and its output is
+not well-suited for conversion back to a DVI file.
+.PP
+The format of \*(Te\& DVI files is fully described
+in
+Donald E. Knuth,
+.IR "\*(Te\&: The Program" ,
+Addison-Wesley (1986), ISBN 0-201-13437-3, as well
+as in the
+.BR dvitype (1)
+literate program source code. Brief descriptions
+of the DTL and DVI formats are given in
+.BR dv2dt (1).

+Correspondence between DTL and DVI files.
+-----------------------------------------
+
+DTL variety sequences-6, version 0.6.0
+--------------------------------------
+
+Note: `DTL' stands for `Device-Independent Text Language', and is an
+ASCII text representation of a DVI file.
+
+References for DVI file structure:
+----------------------------------

+In this distribution:
+
+ dvi.doc
+
+In the TeX archives:
+
+ CTAN: dviware/driv-standard/level-0/dvistd0.tex
+
+ "The DVI Driver Standard, Level 0",
+ by The TUG DVI Driver Standards Committee (now defunct)
+ chaired by Joachim Schrod.
+ Appendix A, "Device-Independent File Format",
+ section A.2, "Summary of DVI commands".
+
+DTL Commands
+------------
+
+ variety <variety-name> Specifies name of DTL file type.
+
+Naturally, `variety' has no DVI equivalent.
+
+The other DTL commands correspond one-to-one with DVI commands, but I
+have used briefer names (except for `special') than those used in the
+DVI standards document.
+
+ DTL : DVI
+
+ (text) : series of set_char commands, for printable ASCII text
+ \( : literal ASCII left parenthesis in (text)
+ \) : literal ASCII right parenthesis in (text)
+ \\ : literal ASCII backslash in (text)
+ \" : literal ASCII double quote in (text)
+ \XY : set_char for character with hexadecimal code XY,
+ not in parentheses, but by itself for readability
+ s1, s2, s2, s3 : set, with (1,2,3,4)-byte charcodes
+ sr : set_rule
+ p1, p2, p2, p3 : put, with (1,2,3,4)-byte charcodes
+ pr : put_rule
+ nop : nop (do nothing)
+ bop : bop (beginning of page)
+ eop : eop (end of page)
+ [ : push
+ ] : pop
+ r1, r2, r3, r4 : right, with (1,2,3,4)-byte argument
+ w0, w1, w2, w3, w4 : as in DVI
+ x0, x1, x2, x3, x4 : as in DVI
+ d1, d2, d3, d4 : down, with (1,2,3,4)-byte argument
+ y0, y1, y2, y3, y4 : as in DVI
+ z0, z1, z2, z3, z4 : as in DVI
+ fn : fnt_num (set current font to font number in 0 to 63)
+ f1, f2, f3, f4 : fnt (set current font to (1,2,3,4)-byte font number)
+ special : xxx (special commands with (1,2,3,4)-byte string length)
+ fd : fnt_def (assign a number to a named font)
+ pre : preamble
+ post : post (begin postamble)
+ post_post : post_post (end postamble)
+ opcode : undefined DVI command (250 to 255)

+.SH DESCRIPTION
+.B dv2dt
+converts a binary \*(Te\& DVI file to an editable
+text file in DTL
+.RI ( "DVI Text Language" )
+format. The companion
+.BR dt2dv (1)
+utility can convert the DTL file back to a binary
+DVI file.
+.\"======================================================================
+.SH "DVI COMMAND DESCRIPTION"
+\*(Te\& DVI files contain a compact binary
+description of typeset pages, as a stream of
+operation code bytes, each immediately followed by
+zero or more parameter bytes. The format of DVI
+files is fully described in Donald E. Knuth,
+.IR "\*(Te\&: The Program" ,
+Addison-Wesley (1986), ISBN 0-201-13437-3, as well
+as in the
+.BR dvitype (1)
+literate program source code.
+.PP
+For convenience, we provide a summary of DVI
+commands here. In the following list, operation
+code bytes are given as unsigned decimal values,
+followed by their symbolic names (not present in
+the DVI file), and a short description. A
+designation like
+.I b[+n]
+means that the operation code byte is followed by
+a parameter
+.I b
+which uses
+.I n
+bytes, and is signed. Without the plus sign, the
+parameter is unsigned. Signed integer parameter
+values are always represented in two's complement
+arithmetic, which is the system followed by most
+computers manufactured today, including all
+personal computers and workstations.

+% This is the TeX source file for the "TeXnical Typesetting" document.
+% Notice how you can put in comments? If TeX sees a % it simply ignores
+% the rest of the line.
+
+% A4 paper is 8.3in wide and 11.7in high; we set the page dimensions so that
+% there are 1in margins all around:
+\hsize 6.3in % page width
+\vsize 9.7in % page height
+
+\parskip 8pt plus 2pt minus 1pt % glue before a paragraph
+
+% Define a few extra fonts for later use:
+\font\bigrm=cmr10 scaled\magstep4 % big version of the standard roman font
+\font\ninerm=cmr9 % 9pt roman
+\font\fiverm=cmr5 % 5pt roman
+\font\sm=cmcsc10 % caps and small caps
+\font\ss=cmss10 % sans serif
+
+% Here's a macro that we'll use to produce all subheadings:
+\def\subhead#1{\bigskip % extra glue before subheading
+ \noindent{\bf #1}\par % unindented boldface subheading
+ \nobreak} % prevent a page break after subheading
+
+\centerline{\bigrm \TeX nical Typesetting}
+
+\vskip 2.5cm % dimensions can be metric
+
+\subhead{What is \TeX?}
+
+\TeX\ (pronounced ``teck'') is a computerized typesetting system developed by
+Donald Knuth and others at Stanford University. It is used to create
+high-quality documents, particularly those containing mathematics.
+The name \TeX\ is an uppercase form of the Greek letters $\tau\epsilon\chi$,
+the first three letters of a Greek word meaning {\sl art} as well as
+{\sl technology}.
+The lowering of the ``E'' is a reminder that \TeX\ is about typesetting,
+which can be thought of as the next stage beyond word processing.
+On devices where such lowering is difficult or impossible you may see \TeX\
+written as {\tt TeX}.
+
+% the above blank line ends the first paragraph
+
+Most word processors allow you to
+create and modify a document interactively --- what
+you see on the screen is usually what your output will look like.
+\TeX\ does {\it not} work in this way.
+Like other typesetting systems (such as SCRIBE and
+{\sl troff\/}), \TeX\ is known as a ``document compiler''. Using your
+favourite text editor you need to create a file containing the
+text of your manuscript along with the \TeX\ typesetting commands.
+\TeX\ gives you the ability to produce printed matter with a quality
+matching that found in books, depending on the output device.
+Adelaide University has an {\sm imagen} laser printer
+with a resolution of 240 dots per inch.
+This publication shows both the capabilities of \TeX\ and
+the output quality of the laser printer.
+
+\subhead{Fonts}
+
+One of the more obvious advantages of \TeX\ is the large range of fonts from
+which you can choose. A font is a collection of characters each having a
+similar size and style. Some of the fonts currently available include:
+$$ % enter display math mode just to get space above and below \line
+\line
+ {\hfil % infinitely stretchable glue
+ \rm roman\hfil \sl slanted\hfil \it italic\hfil \bf boldface\hfil
+ \tt typewriter\hfil \ss sans serif\hfil \sm small caps\hfil
+ } % take care to ensure each { has a matching }
+$$
+Many of these also come in a variety of sizes:
+$$
+\centerline{{\bigrm from the very big},~ % extra space after comma
+ {\ninerm to the very small},~
+ {\fiverm to the ridiculous}.}
+$$
+Apart from a large selection of mathematical symbols,
+many special characters and accents are available:
+$$

+\TeX\ does a few subtle things automatically.
+Certain sequences of characters in your text will
+be replaced by {\sl ligatures} in the printed output (consider the ``{\tt ffi}''
+in ``difficult''), while other pairs of characters need to be {\sl kerned}
+(e.g., the ``o'' and ``x'' in ``box'' look better if they are moved closer
+together). The range and quality of fonts available will continue to improve.
+
+\subhead{Mathematics}
+
+A major design goal of \TeX\ was to simplify the task of typesetting
+mathematics --- and to do it properly. Mathematicians will be pleasantly
+surprised at the ease with which formulae and expressions can be created;
+from simple in-line equations
+such as $e^{i\pi}=-1$ and $f_{n+2}=f_{n+1}+f_n$, to more extravagant displays:
+$$
+\sum_{k\ge1} \sqrt{x_k-\ln k}\quad\ne\quad
+\int_{0}^\infty {e^{-x^3}+\sqrt{x} \over \left(123-x\right)^3} \,dx
+$$
+\TeX\ looks after most of the nitty gritty details, such as spacing things
+correctly and choosing the right sizes for superscripts, parentheses,
+square root signs etc. (The discoverer of the above relation wishes to
+remain anonymous.)
+
+\subhead{Alignment}
+
+The preparation of tabular material such as in lists and matrices can be a
+tedious job for a person armed only with a typewriter and a bottle of
+correction fluid. With a little help from \TeX, computers can make it so
+much easier:
+$$
+\vcenter % a vertically centred \vbox
+ {\tabskip 0pt % no space before column 1
+ \halign to 3.5in % width of table
+ {\strut#& % col 1 is a strut
+ \vrule#\tabskip .5em plus2em& % col 2 is a vrule; also set col spacing

+\vskip -\the\belowdisplayskip % avoid too much space below display
+
+\subhead{Other features}
+
+Space does not permit examples of all the things \TeX\ can do. Here are some
+more features you might like to know about:
+
+\item{$\bullet$}
+Multi-column output can be generated.
+
+{\parskip=0pt % temporarily turn off the skipping between paragraphs
+\item{$\bullet$}
+\TeX\ has a very sophisticated paragraph building algorithm and rarely needs
+to resort to hyphenation. Paragraphs can be indented and shaped in many
+different ways.
+
+\item{$\bullet$}
+Automatic insertion of footnotes,\footnote{\dag}{\ninerm Here is
+a footnote.} running heads, page numbers etc.
+
+\item{$\bullet$}
+\TeX\ makes provision for generating a table of contents, a bibliography, even
+an index. Automatic section numbering and cross referencing are also possible.
+
+\item{$\bullet$}
+A powerful macro facility is built into \TeX. This lets you do some very
+useful things, like creating an abbreviation for a commonly used phrase, or
+defining a new command that will have varying effects depending on the
+parameters it is given. A macro package can enhance \TeX\ by making it much
+easier to generate a document in a predefined format.
+\par % end the last paragraph BEFORE ending the group
+} % \parskip will now revert to its previous value
+
+\subhead{What CAN'T \TeX\ do?}
+
+Complex graphics such as diagrams and illustrations pose
+a major problem --- at the moment you have to leave an appropriate amount of
+blank space and paste them in later.
+Graphic facilities are the subject of current research.
+
+\subhead{\TeX\ and VAX/VMS}
+
+The \TeX\ source file used to generate this document is available for
+inspection on any VAX node that has \TeX ---
+just type `{\tt scroll tex\char'137 inputs:example.tex}'.
+A few steps are needed to print such a file:
+
+\item{(1)}
+Type `{\tt tex example}' to ``compile'' the file.
+(\TeX\ looks for a {\tt .tex} file by default. If it can't find the given
+file in your current directory it will look in {\tt tex\char'137 inputs}.)
+Two new files will be created in your current directory:
+{\tt example.dvi} and {\tt example.lis}.
+The former is a device independent description of the document;
+the latter is simply a log of the \TeX\ run.
+
+{\parskip=0pt % temporarily turn off \parskip
+\item{(2)}
+Type `{\tt dvitovdu example}' to preview the document on a terminal screen.
+This program can be used to detect a variety of formatting problems,
+saving both time and paper.
+
+\item{(3)}
+Type `{\tt imprint example}' to print the document.
+(Note that the DVIto\kern-.15em VDU and IMPRINT commands
+accept a {\tt .dvi} file by default).
+
+} % restore \parskip
+
+Detailed help on all these commands is available on-line --- try typing
+`{\tt help tex}' to get started.

+Our task is to create a paragraph illustrating what a typical piece of text
+looks like in the standard \TeX\ font. It should be stressed that not all
+\TeX\ fonts can be used for typesetting text. We need to show most of the
+characters in this font---for instance, something like ``the quick brown fox
+jumps over a lazy dog'' would use all the lower-case letters. Hmmm \dots\
+how about ``THE QUICK BROWN FOX JUMPS OVER 9876543210 LAZY DOGS'' to make
+sure we show all the upper-case letters and digits? Such a paragraph would
+hardly be typical! Then there's ligatures (try and fit in words like
+fluffy, waffle, firefly, difficult) and examples of kerning (boxer, cooked,
+vowel). Not to mention the various accents and other special letters:
+prot\'eg\'e, r\^ole, na\"\i ve, \AE sop's \OE vres en fran\c cais.
+But how do we put all this stuff into a paragraph that makes sense!?
