112 Introduction and General Information

119 \begin_layout Standard
120 LyX is a program that provides a more modern approach to writing documents
121 with a computer, an approach that breaks with the obsolete tradition of
123 \begin_inset Quotes eld
127 \begin_inset Quotes erd
130 It is designed for authors who want professional output quickly with a
131 minimum of effort without becoming specialists in typesetting.
132 The job of typesetting is done mostly by the computer, not the author;
133 with LyX, the author can concentrate on the contents of her writing.

147 \begin_inset Quotes eld
151 \begin_inset Quotes erd
154 means that the line- and page-breaks are not displayed exactly as they
155 will appear in the printed document.
156 However, that's not really necessary, since LyX uses a separate typesetter
157 program (called LaTeX) to perform the final formatting of your text.
158 While LyX contains everything it needs to be a comfortable user interface,
159 the typesetting program contains everything necessary to format text, and
160 do so very, very well.
164 \begin_layout Standard
165 So, line- and page-breaks aren't your problem anymore.
166 Remembering which number to use for the next subsection isn't your problem
168 Recalling what font you used for all of your section headings isn't your
170 You tell LyX (and LaTeX) what
174 of document you're editing and what
178 of paragraph this-or-that text is, the computer can typeset it accordingly.
179 Of course you can also still do some low-level formatting for fine-tuning.
180 However, the proper way with LyX is to tell the computer what the text
185 , not what it should look like.
186 So, we like to say that LyX gives you WYSIWYM editing (What You See Is

370 Linux distributions: Debian, RedHat, SUSE, Mandrake, Fedora, Ubuntu, Gentoo,

403 \begin_layout Subsection
404 How much hard disk space does LyX need?
407 \begin_layout Standard
408 Binary size depends on the system, the LyX binary consumes 13 MB of disk
409 space on Windows, while the supporting files occupy another 25 MB (17 MB
410 of which is consumed by the docs! You can delete the languages you don't
411 care about to save some space).
412 Of course, you do need to have something like teTeX installed which consumes
413 a mere 115 MB, as well as ghostscript, which is another 10 MB!
416 \begin_layout Subsection
417 Is LyX really Open Source?
420 \begin_layout Standard
422 The freely available GUI toolkit that LyX uses, Qt, although a proprietary
423 product of Troll Tech, is used in its open source GPL variant.
424 The LyX source itself is also available under the GPL, so it qualifies.

766 Questions about Evil Red Text (IMPORTANT!)

770 What is Evil Red Text (aka ERT)?
773 \begin_layout Standard
774 ERT (Evil Red Text) refers to raw LaTeX commands which are inserted into
776 Certain troglodytes in the development group coined this term when they
777 complained about the unsightly appearance it leads to in LyX documents.
778 The more enlightened among us know that it is extremely useful, even though
779 it does qualify as URT (Ugly Red Text), but ERT seems to have stuck.
783 \begin_layout Subsection

1168 \begin_inset Quotes erd
1171 is what you might call a

1176 \begin_inset Quotes erd
1179 ; it basically means insert a picture file.
1181 \begin_inset Quotes eld
1185 \begin_inset Quotes erd

1221 Too many unprocessed floats
1222 \begin_inset Quotes erd
1228 \begin_layout Standard
1229 LaTeX can handle only a limited number of floating elements floating at
1231 For example, if Figure 4 can't be fit in a good location (using the default
1232 rules of top of the page, then bottom, then a page of its own) and Figure
1233 5 comes along, they will both continue to float toward the end of the document
1234 until a good location can be found.
1235 If nothing good turns up, they will just be placed at the end of the document.
1236 If there are too many of these, LaTeX overruns a counter and emits the
1238 \begin_inset Quotes eld
1241 too many unprocessed floats
1242 \begin_inset Quotes erd
1246 This is not a bug in LaTeX, this is simply too many figures with too little
1250 \begin_layout Standard
1251 The easiest way to work around this is to insert a
1257 command somewhere in the document where a pagebreak would be appropriate.
1258 While a pagebreak would simply start a new page,
1264 processes all remaining floats, then begins a new page.
1265 This may lead to an unsightly stack of figures in the middle of your document;
1266 you may need to use several

1445 If LyX has crashed, include the version of LyX, the operating system, the
1446 version of xforms (if it seems to be a screen drawing problem), and a precise
1447 description of the events that lead to the crash.
1448 The easier it is for the developers to reproduce your crash, the more likely
1450 If you're brave and like to hack, use gdb to generate a backtrace and include
1451 the results with your mail.
1452 If you have no clue what I'm talking about, just describe what you did
1453 as completely as you can.

1502 I don't claim anything in this document is accurate to within a factor of
1504 \begin_inset Formula $\pi$
