It excels at letting you create complex technical and scientific articles with mathematics, cross-references, bibliographies, indexes, etc. It is very good for working with documents of any length in which the usual processing abilities are required: automatic sectioning and pagination, spell checking and so forth. It can also be used to write a letter to your mom, though granted, there are probably simpler programs available for that. It is definitely not the best tool for creating banners, flyers, or advertisements (we'll explain why later), though with some effort all these can be done, too. Here are some examples of what it is used for: memos, letters, dissertations and theses, lecture notes, seminar notebooks, conference proceedings, software documentation, books, articles in refereed scientific journals, scripts for plays and movies, business proposals, presentations\SpecialChar ldots \end_layout \begin_layout Standard \SpecialChar LyX is a program that provides a modern approach to writing documents with a computer by using a markup language paradigm, an approach that breaks with the obsolete tradition of the \begin_inset Quotes eld \end_inset typewriter concept \begin_inset Quotes erd \end_inset . It is designed for authors who want professional output quickly with a minimum of effort and without becoming specialists in typesetting. The job of typesetting is done mostly by the computer, not the author; with \SpecialChar LyX , the author can concentrate on the contents of his writing. \end_layout \begin_layout Standard Part of the initial challenge of using \SpecialChar LyX comes from the change in thinking that you, the user, must make. At one time, all we had for creating documents were typewriters, so we all learned certain tricks to get around their limitations. Underlining, which is little more than overstriking with the \begin_inset Quotes eld \end_inset _ \begin_inset Quotes erd \end_inset character, became a way to emphasize text. You were forced to figure out column sizes and tab stops, and set them, before creating a table. The same applied for letters and other right justified text. Hyphenation at the end of a line required a careful eye and a lot of foresight. \end_layout \begin_layout Standard In other words, we've all been trained to worry about the little details of which character goes where. Consequently, almost all word processors have this mentality. They still use tab stops for adding whitespace. You still need to worry about exactly where on the page something will appear. Emphasizing text means changing a font, similar to changing the typewriter wheel. This is the underlying philosophy of a WYSIWYG word processor: \begin_inset Quotes eld \end_inset What You See Is What You Get \begin_inset Quotes erd \end_inset . Unfortunately, that paradigm often results in \begin_inset Quotes eld \end_inset What You See Is All You Get \begin_inset Quotes erd \end_inset . \end_layout \begin_layout Standard This is where \SpecialChar LyX differs from an ordinary word processor. You don't concern yourself with what character goes where. You tell \SpecialChar LyX \emph on what you're doing \emph default and \SpecialChar LyX takes care of the rest, following a set of rules called a \emph on style \emph default . \begin_inset Foot status collapsed \begin_layout Plain Layout To be fair, most recent versions of the most popular office suites now have some sort of style sheets which follow a similar markup method. However, our experience is that they are still rarely used in practice. \end_layout \end_inset Let's look at a little example: \end_layout \begin_layout Standard Suppose you are writing a report. To begin your report, you want a section called \begin_inset Quotes eld \end_inset Introduction \begin_inset Quotes erd \end_inset \SpecialChar endofsentence So, you go into whatever menu it is in your word processor that changes font sizes and decide on a new font size. Then you turn on bold face. Then you type, \begin_inset Quotes eld \end_inset 1. \begin_inset space ~ \end_inset \begin_inset space ~ \end_inset Introduction \begin_inset Quotes erd \end_inset . Of course, if you later decide that this section belongs someplace else in the document or if you insert a new section before it, you need to change the numbering for this and all following sections, as well as any entry in the table of contents. \end_layout \begin_layout Standard In \SpecialChar LyX , you go to the pull-down on the far left of the button bar and select \family sans Section \family default , and type \begin_inset Quotes eld \end_inset Introduction \begin_inset Quotes erd \end_inset . \end_layout \begin_layout Standard Yes, that's all. If you cut and paste the section, it will automatically be renumbered — everywhere. And if you enter references to that section correctly (by inserting cross-reference tags), \SpecialChar LyX will automatically update them all throughout the file so that you never, ever type a section number. \end_layout \begin_layout Standard Now let's look at the problem of consistency. Five days later, you reopen your report and start Section \begin_inset space ~ \end_inset 4. However, you forget that you were using 18 \begin_inset space \thinspace{} \end_inset pt bold instead of 16 \begin_inset space \thinspace{} \end_inset pt, so you type in the heading for Section \begin_inset space ~ \end_inset 4 in a different font from the one you used for Section \begin_inset space ~ \end_inset 1. That problem doesn't even exist in \SpecialChar LyX . The computer takes care of all that silly bookkeeping about which thing has what size font, not you. After all, that's what a computer is good at. \end_layout \begin_layout Standard Here's another example. Suppose you're making a list. In other word processors, a list is just a bunch of tab stops and newlines. You need to figure out where to put the label for each list item, what that label should be, how many blank lines to put between each item, and so on. Under \SpecialChar LyX , you have only two concerns: what kind of list is this, and what do I want to put in it? That is it. \end_layout \begin_layout Standard So, the basic idea behind \SpecialChar LyX is: specify \emph on what \emph default you're doing, not \emph on how \emph default to do it. Instead of \begin_inset Quotes eld \end_inset What You See Is What You Get \begin_inset Quotes erd \end_inset , the \SpecialChar LyX model is \begin_inset Quotes eld \end_inset What You See Is What You \emph on Mean \emph default \begin_inset Quotes erd \end_inset or WYSIWYM. It's a powerful idea that greatly simplifies the mechanics of writing documents. This is also why \SpecialChar LyX isn't so good for creating posters and flyers. In this case, you \emph on do \emph default want to specify exactly where everything goes, because there are no functional units like paragraphs, sections, etc. This doesn't mean \SpecialChar LyX is missing some cool function. It simply means that it isn't the right tool for the job — you don't use a screwdriver to drive in nails. \end_layout \begin_layout Subsection Differences between \SpecialChar LyX and Other Word Processors \end_layout \begin_layout Standard Here's a list of things you won't find in \SpecialChar LyX : \end_layout \begin_layout Itemize The document ruler \end_layout \begin_layout Itemize Tab stops \end_layout \begin_layout Itemize Extra whitespace (e. \begin_inset space \thinspace{} \end_inset g. \begin_inset space \space{} \end_inset hitting \family sans Enter \family default or \family sans Space \family default two or more times) \end_layout \begin_layout Standard Tab stops, along with a ruler showing you the position of things on the page, are useless in \SpecialChar LyX . The program worries about where things go on the page, not you. Extra whitespace is similar; \SpecialChar LyX adds it where necessary, depending on context. Not being able to type two blank lines in a row will be annoying at first, but it makes more sense once you're thinking in WYSIWYM terms. \end_layout \begin_layout Standard Here are some things that exist in \SpecialChar LyX , but aren't used as you might think: \end_layout \begin_layout Itemize Indenting controls \end_layout \begin_layout Itemize Page breaks \end_layout \begin_layout Itemize Line spacing (e. \begin_inset space \thinspace{} \end_inset g. \begin_inset space \space{} \end_inset single spaced, double spaced, etc.) \end_layout \begin_layout Itemize Whitespace, horizontal and vertical \end_layout \begin_layout Itemize Fonts and font sizes \end_layout \begin_layout Itemize Typefaces (bold, italic, underline, etc.) \end_layout \begin_layout Standard Although they exist in \SpecialChar LyX , you generally don't need them. \SpecialChar LyX will take care of these things for you, depending on what you're doing. Different parts of the document are automatically set in a different typeface and font size. Paragraph indenting is context dependent; different types of paragraphs get indented differently. Page breaks get handled automatically, as well. In general, the space between lines, between words, and between paragraphs is variable, set by \SpecialChar LyX . \begin_inset Foot status collapsed \begin_layout Plain Layout There are ways to adjust all of these (only some of which require knowledge of \SpecialChar LaTeX ), either for a whole document or for a specific location in a document. See the \emph on User's Guide \emph default and/or the \emph on Additional Features \emph default manual for details. \end_layout \end_inset \end_layout \begin_layout Standard Lastly, there are a few areas where we believe \SpecialChar LyX (and \SpecialChar LaTeX ) surpasses many word processors: \end_layout \begin_layout Itemize Hyphenation \end_layout \begin_layout Itemize Lists of any type \end_layout \begin_layout Itemize Mathematics \end_layout \begin_layout Itemize Tables \end_layout \begin_layout Itemize Cross-referencing \end_layout \begin_layout Standard Granted, many modern word processors can handle mathematical symbols, tables, and hyphenation, and many have moved towards style definitions and the WYSIWYM concept. However, they've only recently been able to do so, whereas \SpecialChar LyX is built upon the \SpecialChar LaTeX document preparation system. \SpecialChar LaTeX has been around since 1985, and \emph on works \emph default . \end_layout \begin_layout Subsection What is \SpecialChar LaTeX ? \end_layout \begin_layout Standard \SpecialChar LaTeX is a document preparation system designed by \noun on Leslie Lamport \noun default in 1985. \begin_inset Foot status collapsed \begin_layout Plain Layout The source for the info in this section is \emph on A Guide to \SpecialChar LaTeX2e \emph default , by \noun on Helmut Kopka \noun default and \noun on Patrick Daly \noun default , which has an entry in the bibliography of the \emph on User's Guide \emph default \SpecialChar endofsentence \end_layout \end_inset It was built up from a typesetting language called \SpecialChar TeX , created by \shape smallcaps Donald Knuth \shape default in 1984. \SpecialChar TeX takes a sequence of typesetting commands, written in a script in an ASCII file, and executes them. Many of the \begin_inset Quotes eld \end_inset tricks \begin_inset Quotes erd \end_inset of the printing trade were modeled by \shape smallcaps Knuth \shape default as computer algorithms and incorporated into \SpecialChar TeX , hence its excellent printed appearance. What comes directly out of \SpecialChar TeX is the \begin_inset Quotes eld \end_inset portable document format \begin_inset Quotes erd \end_inset \emph on pdf \emph default or the so-called \begin_inset Quotes eld \end_inset device independent \begin_inset Quotes erd \end_inset format file \emph on dvi \emph default . The \family typewriter dvi \family default format is often used for previews and can later be converted to other formats like PostScript. \end_layout \begin_layout Standard \SpecialChar TeX isn't only a typesetting engine; it also allows you to define macros. Most people who use \SpecialChar TeX are actually using a macro package which \noun on Knuth \noun default created to hide a lot of the typesetting details. This is where \noun on Leslie Lamport \noun default enters our story. He wanted a macro package that was more user- and less typesetter-oriented, with a set of commands that consistently typeset things like sections, tables or math formulas in a uniform, consistent fashion. This is how \SpecialChar LaTeX was born. \end_layout \begin_layout Standard Now, in parallel with the development and growth of \SpecialChar LaTeX , other folks were creating their own custom macro packages for \SpecialChar TeX , ones to make slides or articles for math journals and so on. Some used the raw \SpecialChar TeX facilities to do this, others began modifying \SpecialChar LaTeX . To try and unify this mess, a team of \SpecialChar LaTeX -nicians began to work on \SpecialChar LaTeX2e , the current version of \SpecialChar LaTeX , during the late 1980's. This new version of \SpecialChar LaTeX has commands which provide an easier-to-use interface to \SpecialChar TeX 's macro-creating commands, aid in the use of new fonts, and so on. In fact, \SpecialChar LaTeX is quite an extensive language in its own right! Users around the world have been creating their own add-ons for \SpecialChar LaTeX beyond the standard ones. \end_layout \begin_layout Standard There are two ways to extend \SpecialChar LaTeX : classes and styles. A \emph on class \emph default is a set of \SpecialChar LaTeX macros describing a new type of document, like a book, or an article. There are classes for slides, for physics and math journals\SpecialChar ldots many universities even have a class for their thesis format. A \emph on style \emph default differs from a class in that it doesn't define a new type of document, but a different type of \emph on behavior \emph default that any document can use. For example, \SpecialChar LyX controls page margins and line spacing using two different \SpecialChar LaTeX style-files designed for these purposes. There are style-files for a whole slew of things: printing labels or envelopes, changing indentation behavior, adding new fonts, manipulating graphics, designing fancy page headings, customizing bibliographies, altering the location and appearance of footnotes, tables, and figures, customizing lists, etc. \end_layout \begin_layout Standard Here is a summary: \end_layout \begin_layout Description \SpecialChar TeX : Typesetting language with macro capability. \end_layout \begin_layout Description \SpecialChar LaTeX : Macro package built upon \SpecialChar TeX \SpecialChar endofsentence \end_layout \begin_layout Description classes: Descriptions of types of document used with \SpecialChar LaTeX \SpecialChar endofsentence \end_layout \begin_layout Description styles: Descriptions of the default behavior of particular elements of \SpecialChar LaTeX . \end_layout \begin_layout Description \SpecialChar LyX : Visual, WYSIWYM document processor that uses \SpecialChar LaTeX to do its typesetting. \end_layout \begin_layout Standard This section attempts to explain the difference between \SpecialChar LyX and a word processor. Simply put, \SpecialChar LaTeX is the difference. By using \SpecialChar LaTeX as its backend, \SpecialChar LyX helps you to think more about \emph on what \emph default (as in the \emph on words \emph default ) you write. The computer then handles \emph on how \emph default they should look. \end_layout \begin_layout Section Navigating the Documentation \end_layout \begin_layout Standard To make it easier to answer your questions and describe all of the features of \SpecialChar LyX , the documentation has been split up into several different files. Each one has its own purpose, as described below. Before you go ploughing into any of those files, however, you should read this section thoroughly, since it contains a lot of useful information and commentary that can save you some time. \end_layout \begin_layout Standard Hopefully, the development of \SpecialChar LyX will never stop; so some of the documentation may be incomplete or a bit out of date, though we try to keep up-to-date. Like the rest of \SpecialChar LyX , the manuals are the work of a group of volunteers who have \begin_inset Quotes eld \end_inset Real Jobs \begin_inset Quotes erd \end_inset , families, dishes to clean, \emph on et cetera \emph default . If you want to help out, be sure to read Section \begin_inset space ~ \end_inset \begin_inset CommandInset ref LatexCommand ref reference "sec:Contrib" nolink "false" \end_inset in addition to the rest of this document. \end_layout \begin_layout Standard Also, please do us a favor: if anything in these manuals confuses you, is unclear, or wrong, don't hesitate to let us know! You can reach the current documentation maintainers by emailing \begin_inset CommandInset href LatexCommand href target "lyx-docs@lists.lyx.org" type "mailto:" literal "false" \end_inset . \end_layout \begin_layout Subsection Where To Get Help \end_layout \begin_layout Standard If you have questions that are not obviously answered in the documentation and need help fast, there is an active users' mailing list which you can reach at \begin_inset CommandInset href LatexCommand href target "lyx-users@lists.lyx.org" type "mailto:" literal "false" \end_inset . You do not have to register to post, but you may wish to do so. See \begin_inset CommandInset href LatexCommand href name "the LyX website" target "https://www.lyx.org/MailingLists" literal "false" \end_inset for further information. LyX also has a \begin_inset CommandInset href LatexCommand href target "https://www.lyx.org" literal "false" \end_inset that will answer many questions about how to get LyX to do various things. \end_layout \begin_layout Subsection The Format of the Manuals \end_layout \begin_layout Standard Some of you may have printed out the manuals. Others may be reading them within \SpecialChar LyX . There are some differences between the \SpecialChar LyX -file and the printed version. In \SpecialChar LyX , the title is simply at the top of the document, not formatted on a separate page as in some of the printed versions. Nor are any of the footnotes or the Table of Contents fully visible. To open a footnote, which looks like this: \begin_inset Graphics filename clipart/footnote.png scale 95 \end_inset , click on it with the left mouse button. For the Table of Contents, either click on the grey box or click on the \family sans Navigate \family default menu, where the contents are displayed automatically\SpecialChar endofsentence \end_layout \begin_layout Standard In the printed manuals, all cross-references appear as the actual numbers for a chapter, section, subsection, and so on. In the \SpecialChar LyX -file, however, all cross-references appear as light-grey boxes like the following: \begin_inset Graphics filename clipart/reference.png scale 95 \end_inset . If you click on such a box with the left mouse button, a dialog box will appear containing a list of all the cross-references in the document. You can go to the referenced element by right-clicking on the box or by clicking the button \family sans Go \begin_inset space ~ \end_inset to \begin_inset space ~ \end_inset Label \family default in the opened dialog. Going back to where you came from is just as easy. Click on \family sans Go \begin_inset space ~ \end_inset Back \family default to go back to your earlier location. \end_layout \begin_layout Standard Now that we've cleared up some of the differences between the printed and \SpecialChar LyX -file versions of this file, we can start looking at the format of this document. You'll occasionally notice things in different fonts: \end_layout \begin_layout Itemize \emph on Emphasized Style \emph default is used for general emphasis, generic arguments, book and manual titles, names of sections of other manuals, and notes from the authors. \end_layout \begin_layout Itemize \family typewriter Typewriter \family default is used for program and file names, \SpecialChar LyX code and functions. \end_layout \begin_layout Itemize \family sans Sans Serif \family default is used for menu, button or dialog box names, and the names of keyboard keys. \end_layout \begin_layout Itemize \noun on Noun Style \noun default is used for people's names. \end_layout \begin_layout Itemize \series bold Bold \series default is used for \SpecialChar LaTeX code. \end_layout \begin_layout Standard When we do need to reference keys, we'll use the following prefixing convention: \end_layout \begin_layout Itemize \family sans Ctrl+ \family default indicates the \family sans Control \family default key. \end_layout \begin_layout Itemize \family sans Shift+ \family default indicates the \family sans Shift \family default key. \end_layout \begin_layout Itemize \family sans Alt+ \family default indicates the \family sans Alt \family default ( \family sans Meta \family default ) key. \end_layout \begin_layout Itemize \family sans F1 \family default \SpecialChar ldots \family sans F12 \family default are the function keys. \end_layout \begin_layout Itemize \family sans Esc \family default is the escape key. \end_layout \begin_layout Itemize \family sans Left \family default , \family sans Right \family default , \family sans Up \family default and \family sans Down \family default : self-explanatory. \end_layout \begin_layout Itemize \family sans Insert \family default , \family sans Delete \family default , \family sans Home \family default , \family sans End \family default , \family sans PageUp \family default and \family sans PageDown \family default : these are the 6 \begin_inset space ~ \end_inset keys that appear above the cursor keys on many PC keyboards. \family sans PageUp \family default and \family sans PageDown \family default are called \family sans Prior \family default and \family sans Next \family default on some keyboards. \end_layout \begin_layout Itemize \family sans Return \family default and \family sans Enter \family default both refer to the same key. Some keyboards label the \family sans Return \family default key as \begin_inset Quotes eld \end_inset Return \begin_inset Quotes erd \end_inset , others as \begin_inset Quotes eld \end_inset Enter \begin_inset Quotes erd \end_inset , still others have two keys. \SpecialChar LyX treats all of them as the same key, so we'll use \family sans Return \family default and \family sans Enter \family default interchangeably. \end_layout \begin_layout Standard The list with the currently set shortcuts can be found in the \family sans Help \family default menu under \family sans Shortcuts \family default . \end_layout \begin_layout Subsection Units used in the Manuals \end_layout \begin_layout Standard To understand the units described in this documentation, Table \begin_inset space ~

The main manual assumes that you have read the \emph on Tutorial \emph default . \end_layout \begin_layout Description Embedded \begin_inset space ~ \end_inset Objects Extension of the \emph on User's Guide \emph default . Documents in detail how to use tables, graphics, floats, notes, program listings and boxes. It also includes many tricks of the \SpecialChar LaTeX masters. \end_layout \begin_layout Description Math Extension of the \emph on User's Guide \emph default . Documents in detail how to typeset any kind of formula. \end_layout \begin_layout Description Additional \begin_inset space ~ \end_inset Features Extension of the \emph on User's Guide \emph default . Documents how to use raw \SpecialChar LaTeX commands, additional layouts and special-purpose editing features. \end_layout \begin_layout Description Customization A description of advanced \SpecialChar LyX features, including how to customize the overall behavior of \SpecialChar LyX \SpecialChar endofsentence This includes such things as keybindings, internationalization and configuration files. It also includes information about layout files, which are needed to get \SpecialChar LyX to support \SpecialChar LaTeX classes or packages. \end_layout \begin_layout Description Shortcuts Tables of the currently defined \SpecialChar LyX shortcuts. \end_layout \begin_layout Description \SpecialChar LaTeX \begin_inset space ~ \end_inset Configuration A report produced by \SpecialChar LyX about your system. This file contains information on what \SpecialChar LyX learned about your installation. Check it to see if you're missing something you might like to have. \end_layout \begin_layout Standard These files will reference one another as necessary. For example, the \emph on User's Guide \emph default contains \emph on some \emph default information on installation and customization, but refers the reader to the \emph on Customization \emph default manual for more information. \end_layout \begin_layout Standard We'll state again an important point: \end_layout \begin_layout Standard \begin_inset VSpace bigskip \end_inset \end_layout \begin_layout Standard \align center If you are new to \SpecialChar LyX , read the \emph on Tutorial \emph default .

It is a large project, and as a result it is not free from bugs, or the need for improvements in the source code. \end_layout \begin_layout Subsubsection Reporting a bug \end_layout \begin_layout Standard While using \SpecialChar LyX , you may find behavior which you consider a bug. Crashes, though rare, can happen. User interface problems are considered major bugs by the \SpecialChar LyX team: especially helpful are indications of parts of the \SpecialChar LyX interface you find confusing, or unclear. \end_layout \begin_layout Standard \SpecialChar LyX has a bug tracking system, which you can find at \begin_inset Newline newline \end_inset \begin_inset CommandInset href LatexCommand href target "https://www.lyx.org/trac/wiki/BugTrackerHome" \end_inset . You should check the bug tracker before reporting any bugs, in case it has already been reported. If you have a comment on an existing bug, or wish to report a new bug, you may either use the bug tracker, or send an e-mail to the development mailing list, \begin_inset CommandInset href LatexCommand href target "lyx-devel@lists.lyx.org" type "mailto:" literal "false" \end_inset . Archives of this list are linked from the main \SpecialChar LyX website, \begin_inset CommandInset href LatexCommand href target "https://www.lyx.org/MailingLists" literal "false" \end_inset . \end_layout \begin_layout Standard A useful bug report will at a minimum include the version of \SpecialChar LyX you are having the problem with. Accurate, detailed descriptions are preferred — the more time developers have to spend to pinpoint the source of a bug, the less time they have for other improvements. Mention the system and system version on which you are running \SpecialChar LyX . Give the versions of the libraries you have installed on your system, and, if relevant, the versions of external programs that \SpecialChar LyX uses. If it's a compilation or configuration problem, include the file \family typewriter config.log \family default , and mention which compiler you are using. Part of this information can be found in \family sans Help\SpecialChar menuseparator About \family default . \end_layout \begin_layout Subsubsection Contributing fixes and new features \end_layout \begin_layout Standard If you have made changes to \SpecialChar LyX 's source that you think should become part of \SpecialChar LyX , send your changes as a diff file (in unified format) to the development list referenced above, along with a change log, and a description of what your patch does. \end_layout \begin_layout Subsection Contributing to the Documentation \end_layout \begin_layout Standard \SpecialChar LyX 's documentation is extensive; however \SpecialChar LyX is under constant development, and each new release adds new features. You may find some documentation needs improvement. This section describes what to do if you find an error, or have some suggestions for improving the documentation. \end_layout \begin_layout Subsubsection Reporting Errors in the Manuals \end_layout \begin_layout Standard If you find a problem with the documentation, send a message to the mailing list \begin_inset CommandInset href LatexCommand href target "lyx-docs@lists.lyx.org" type "mailto:" literal "false" \end_inset . The documentation team will make any necessary fixes. \end_layout \begin_layout Subsubsection Joining the Documentation Team. \end_layout \begin_layout Standard The \SpecialChar LyX Documentation Project, like anything else in the \SpecialChar LyX project, can always use assistance! If you're interested in contributing to the Documentation Project, you need to do the following: \end_layout \begin_layout Enumerate Get the latest \SpecialChar LyX source code from \begin_inset Newline newline \end_inset \begin_inset CommandInset href LatexCommand href target "https://www.lyx.org/trac/browser/lyxgit/lib/doc?rev=master " \end_inset \end_layout \begin_layout Enumerate Next, read the \emph on User's Guide \emph default and the \emph on Tutorial \emph default \SpecialChar endofsentence \begin_inset Newline newline \end_inset The point of this exercise is to give you ideas. The \emph on Tutorial \emph default and \emph on User's Guide \emph default are likely to be the most up-to-date of all of the documentation. You should be able to glean some insights into how we want the manuals to read and to look. \end_layout \begin_layout Enumerate Contact the team at: \begin_inset Newline newline \end_inset \begin_inset CommandInset href LatexCommand href target "lyx-docs@lists.lyx.org" type "mailto:" literal "false" \end_inset \begin_inset Newline newline \end_inset to discuss your intended changes and to get some feedback on them. \end_layout \begin_layout Standard The changes you wish to make may range from improving clarity of the text, to doing major re-structuring of the documentation. Any and all improvements are gladly received. \end_layout \end_body \end_document
