    50 \subsection{What is a \vym map?}
    51 A \vym map (in short words {\em map}) is a tree like structure:
    52 \begin{center}
    53 	\includegraphics[width=12cm]{example1.png}
    54 \end{center}
    55 Such maps can be drawn by hand on a paper or flip chart and help to
    56 structure your thoughts. While a tree like structure like above can be
    57 drawn manually \vym offers much more features to work with such maps.
    58 \vym is not another drawing software, but a tool to store and modify
    59 information in an intuitive way. For example you can reorder parts of
    60 the map by pressing a key or add various information like a complete
    61 email by a simple mouse click.
    62 
    63 Once you have finished collecting and organizing your ideas, you can
    64 easily generate for example a presentation in Open~Office based on a
    65 map.
    66 
    67 \subsection{Why should I use maps? Time, Space and your Brain.}
    68 \subsubsection*{Space}
    69 A map can concentrate a very complex content on little space e.g. a
    70 piece of paper. It helps to use both sides of your brain: the logical
    71 side and also your creative side (e.g. by using pictures, colors and
    72 keywords in a map, so called {\em anchors}).  It is a technique to
    73 organize the way you think: It can help you by developing, sorting and
    74 memorizing your thoughts. 
    75 
    76 \subsubsection*{Time}
    77 Because you just use keywords and drawings, it is much faster than good
    78 old fashioned notes. Your brain memorizes things by associating them to
    79 other things -- a map makes use of those connections and stimulates
    80 new asccociations. 
    81 
    82 
    83 \subsubsection*{Your Brain}
    84 In 1960 the Prof. {\sc Roger Sperry} discovered that both hemispheres
    85 of the human brain have different tasks (of course both of them
    86 basically {\em can} do the same): 
    87 \begin{center}
    88 \begin{tabular}{|p{5.5cm}|p{5.5cm}|} \hline
    89 	Left side & Right side \\ \hline
    90 	\begin{itemize}
    91 	   \item verbal speech and writing 
    92 	   \item numbers
    93 	   \item logical thinking
    94 	   \item analyzing and details
    95 	   \item science
    96 	   \item linear thinking
    97 	   \item concept of time
    98 	\end{itemize} &
    99 	\begin{itemize}
   100 		\item body language
   101 		\item visual thinking, day dreams
   102 		\item intuition and emotion
   103 		\item overview of things
   104 		\item creativity
   105 		\item art, music, dancing
   106 		\item non-linear thinking, connecting things
   107 		\item spatial awareness
   108 	\end{itemize}     \\ \hline
   109 \end{tabular}	
   110 \end{center}
   111 In our science oriented society we have learned to mainly rely on our
   112 left side of the brain, the "rational" one. In other cultures,
   113 especially like the native americans and other "old" cultures, the right
   114 side is much more important. Maps are just one way to stimulate the
   115 other side and make use of additional ressources we all have.
   116 
   117 
   118 \subsection{Where could I use a map?}
   119 Here are some examples, how you can use those maps
   120 \begin{itemize}
   121     \item to prepare articles, papers, books, talks, \ldots
   122     \item to sort complex data
   123     \item to memorize facts, persons, vocabulary, \ldots
   124     \item to sort emails, files and bookmarks on your computer
   125     \item to moderate conferences
   126 \end{itemize}
   127 
   128 \subsection{What you shouldn't do with a map...}
   129 A map drawn by somebody shows the way the author thinks. There is
   130 no right or wrong in the way it is drawn, so there is no way to criticize
   131 it. "It is, what it is" ({\sc F.~Lehmann}).
   132 
   133 %\section{Tutorials}
   134 %TODO
   135 
   136 \subsection{Internet Ressources} 
   137 A good starting point to learn more about maps in general is Wikipedia:
   138 \begin{itemize}
   139 	\item English: 
   140 		\href{http://en.wikipedia.org/wiki/Mind_map}{http://en.wikipedia.org/wiki/Mind\_map}
   141 	\item German: 
   142 		\href{http://de.wikipedia.org/wiki/Mindmap}{http://de.wikipedia.org/wiki/Mindmap}
   143 \end{itemize}
   144 
   145 
   146 
   147 
   148 \section{Concept of \vym}
   149 %TODO may add a general introduction here...
   150 \subsection{Windows: mapeditor and noteeditor}
   151 \vym uses two windows: an editor for the map itself and another one for
   152 notes, which are part of the map. Let's call them {\em mapeditor} and
   153 {\em noteeditor}: 
   154 \begin{center}
   155 	\includegraphics[width=8cm]{windows.png}
   156 \end{center}
   157 Usually you will work in the {\em mapeditor} by just adding new
   158 branches, moving around and reordering them. The various ways to do this
   159 will be explained in \ref{mapeditor}. You can store additional
   160 information e.g. the content of a email easily in a {\em branch}: Just
   161 type or copy\&paste it into the {\em noteeditor}. Working with notes is
   162 explained in \ref{noteeditor}
   163 
   164 \subsection{Menus and Context menus}
   165 On top of each window you find the menubar. The options you find there
   166 are similar to those you are used from other applications. Note that
   167 many (and even more) options are availabe via {\em context menus}. Those
   168 are available if you right-click onto an object in a map (on Mac~OS~X
   169 Command-Click).
   170 
   171 \subsection{Toolbars}
   172 The toolbars in the mainwindows give quick access to many functions and
   173 also visualize the state of an object. For example a part of of the map
   174 can be hidden when the map is exported into an Open~Office presentation.
   175 To show this the branch in the map will have a little cloud symbol,
   176 which is also "switched on" in the toolbar.
   177 
   178 Note that you can reposition all toolbars by simply grabbing them. For
   179 example you can move the flags-toolbar from its original horizontal
   180 position on top of the mapeditor to a vertical position on the right
   181 side. You can even detach it and make it "float" separate from the other
   182 windows. Or just insert it again at its original position.
   183 
   184 \subsection{Maps}
   185 The map itself has always a {\em mapcenter}.  The
   186 mapcenter has {\em branches} just like the trunk of a tree. Each branch
   187 in turn may have branches again.
   188 \begin{center}
   189 	\includegraphics[width=10cm]{branches.png}
   190 \end{center}
   191 We will call a branch directly connected to the mapcenter a {\em
   192 mainbranch}, because it determines the position of all its child
   193 branches.
   194 
   195 The mapcenter and the branches all have a {\em heading}. This is the
   196 text you see in the mapeditor. Usually it should just be one or a few
   197 words, so that one can easily keep track of the whole map.
   198 
   199 
   200 In the toolbar above the mapeditor you see various symbols.
   201 \begin{center}
   202 	\includegraphics[width=8cm]{default-flags.png}
   203 \end{center}
   204 These are called {\em flags} and can be used to mark branches in the
   205 map, e.g. if something is important or questionable. 
   206 There are also more flags set by \vym automatically to show additional
   207 information, e.g. when a  exists for a  particular branch.
   208 
   209 By default some of these flags are set exclusively e.g. when the 
   210 "thumb-up" flag is set, then the "thumb down" is unset and vice
   211 versa. You can change this default behaviour in the settings menu.
   212 
   213 %TODO add info about toolbars e.g. undo/redo, ...
   214 
   215 \section{Mapeditor} \label {mapeditor}
   216 \subsection{Start a new map}
   217 After \vym is started two windows will open: the mapeditor and the
   218 noteditor. Usually you will work in both windows, but at the moment we
   219 will just need the mapeditor. 
   220 
   221 Select the mapcenter "New map" in the middle of the mapeditor by
   222 left-clicking with the mouse. It will turn yellow to show that is
   223 selected. There are several ways to add a new branch to the center:
   224 \begin{itemize}
   225 	\item Using the mouse: Open the context meny by clicking with the
   226 	right mouse button (CTRL-Click on Mac) onto the
   227 	mapcenter and choose Add \ra Add as child
   228 	\item Press \key{Ins} or \key{A}
   229 \end{itemize}
   230 A new branch will appear and you will be able to type the heading of the
   231 branch. Finish adding the new branch by pressing \key{Enter}.
   232 %tipp
   233 Sometimes it comes handy to add a new branch above or below the current
   234 one. Use \key{Ins} together with \key{Shift} or \key{Ctrl}. It is also
   235 possible to add a branch in such a way, that the current selection
   236 becomes the child of the new branch, which is like inserting it {\em
   237 before} the selection. This can be done using the context menu.
   238 
   239 \subsection{Navigate through a map}
   240 \subsubsection*{Select branches}
   241 To select branches you can use the left button of your mouse or also the
   242 arrow keys. Depending on the {\em orientation} of a branch type
   243 \key{\la} or \key{\ra} to get nearer to the mapcenter or deeper
   244 down into the branches. Within a set of branches, let's call them a 
   245 {\em subtree}, you can use \key{\ua} and \key{\da} to go up and down. You can
   246 also use \key{Pos1} and \key{End} to select the first and last branch.
   247 
   248 
   249 \subsubsection*{Zoom a map}
   250 While adding more and more branches the size of the map may become
   251 bigger than the mapeditor window. You can use the scrollbars on the
   252 right and the bottom of your mapeditor window to scroll, but it is
   253 easier to just scroll using the left mouse button: Click onto the {\em
   254 canvas} itself, the empty space somewhere between the branches. The
   255 mouse pointer will change from an arrow to a hand, now move the visible
   256 part of the map to show the desired part.
   257 
   258 If you select branches using the arrow keys, the map will scroll
   259 to ensure that the selected branch is always visible.
   260 
   261 Working with huge maps, the {\em zoom}-function comes in handy: You can
   262 use 
   263 \begin{itemize}
   264 	\item from the menu View \ra Zoom
   265 	\item the toolbar buttons 
   266 		\begin{center}
   267 			\includegraphics[width=3cm]{zoom-buttons.png}
   268 		\end{center}	
   269 \end{itemize}	
   270 The crossed magnifying lens resets the zoomed view to its original size.
   271 
   272 
   273 \subsubsection*{Find Function} \label{findwindow}
   274 With huge maps there is the need to have a
   275 find function. Choose Edit \ra Find to open the Find Window:
   276 \begin{center}
   277 	\includegraphics[width=6cm]{find-window.png}
   278 \end{center}	
   279 The text you enter here will be searched in all the headings and also in
   280 notes. Everytime you press the "Find"-button it will look for the next
   281 occurence, which then will be selected automatically. If the search
   282 fails, there will appear a short message "Nothing found" or a few
   283 seconds in the {\em statusbar} on the bottom of the mapeditor.
   284 
   285 \subsubsection*{Keep the overview -- scroll a part of the map}
   286 A very big subtree of a map e.g. a branch with hundreds of childs makes
   287 it very hard to keep an overview over the whole map. You can hide all
   288 the childs of a branch by {\em scrolling} it -- this function is also
   289 often called {\em folding}. Think of the whole subtree as painted onto a
   290 big newspaper. You can scroll the paper to a small roll, leaving just
   291 the headline readable.
   292 
   293 To scroll or unscroll a branch and its childs, press the
   294 \begin{itemize}
   295 	\item \key{Scroll} key or  \key{S}
   296 	\item press the middle-mouse button or
   297 	\item choose the little scroll from the toolbar.
   298 \end{itemize}
   299 If you select parts of a scrolled branch e.g. using the find function or
   300 by using the arrow-keys, it will unscroll temporary. This is shown as a
   301 scroll with a little hour glass. If the temporary unscrolled part is not
   302 longer needed, it will be hidden again automatically. It is also
   303 possible to unscroll all branches using "Edit\ra Unscroll all scrolled
   304 branches".
   305 
   306 You can also hide parts of the map while exporting it e.g. to a webpage
   307 or a presentation, see \ref{hideexport} for details.
   308 
   309 \subsection{Modify and move branches}
   310 \subsubsection*{Modify the heading}
   311 You can edit the heading by selecting the branch and then
   312 \begin{itemize}
   313 	\item pressing \key{Enter}
   314 	\item double-clicking with left mouse.
   315 \end{itemize}
   316 Just type the new heading (or edit the old one) and press \key{Enter}.
   317 
   318 \subsubsection*{Move a branch}
   319 The easiest way to move a branch is to select it with left-mouse and
   320 drag it to the destination while keeping the mouse button pressed.
   321 Depending on the branch  it will be
   322 \begin{itemize}
   323 	\item moved to the destination or
   324 	\item {\em linked} to a new {\em parent} (mapcenter or branch)
   325 \end{itemize}
   326 If you drag the branch over another one or over the mapcenter, you will
   327 notice that the  link connecting it to the old parent will be changed to
   328 lead to the  new parent which is now under your mousepointer. 
   329 If you release the button now, the branch will be relinked.
   330 
   331 If you release the button in the middle of nowhere, the result will
   332 depend on the type of branch you are releasing:
   333 \begin{itemize}
   334 	\item A mainbranch is directly connected to the mapcenter.
   335 		It will stay on its new position.
   336 	\item An ordinary branch will "jump" back to its original position.	
   337 \end{itemize}
   338 Thus you can easily rearrange the layout of the mainbranches to avoid
   339 overlapping of their subtrees.
   340 There is another convenient way to move branches, especially if you want
   341 to {\em reorder} a subtree: You can move a branch up or down in a
   342 subtree by
   343 \begin{itemize}
   344 	\item pressing \key{\ua} and \key {\da}
   345 	\item selecting Edit \ra Move branch
   346 	\item clicking on the toolbar buttons:
   347 		\begin{center}
   348 			\includegraphics[width=1.5cm]{move-buttons.png}
   349 		\end{center}	
   350 \end{itemize}
   351 %tipp
   352 There is yet another way to move branches: If you press \key{Shift} or
   353 \key{Ctrl} while moving with the mouse, the branch will be added above
   354 or below the one the mouse pointer is over. This helps also to reorder a
   355 map.
   356 
   357 \subsection{The right side of your brain - colors and images}
   358 \subsubsection*{Change color of a heading}
   359 You can also use colors to put more information into a map, e.g. use
   360 red, green and more colors to prioritize tasks. Again you can
   361 \begin{itemize}
   362 	\item use the menu and choose e.g Format \rq Set Color
   363 	\item use the toolbar
   364 		\begin{center}
   365 			\includegraphics[width=3cm]{color-buttons.png}
   366 		\end{center}	
   367 \end{itemize}
   368 The first button (black in the graphic above) shows the actual color.
   369 Clicking on it let's you choose another color. You can also "pick"
   370 another color by selecting a branch with the desired color and using the
   371 "pick color" button. Both of the buttons showing a bucket actually put
   372 the current color to the selected branch. While the first one just
   373 colors the heading of the selection, the last one also colors all the
   374 childs of the selected branch.
   375 
   376 %tipp
   377 A very useful function is the "copy color" using the mouse: Select the
   378 branch which should get the new color, then press \key{Ctrl} and
   379 simultanously click with left-mouse on another branch to copy its color
   380 to the first one. Here the childs of the selection also will get the new
   381 color, if you just want to color the selection itself, additionally
   382 press \key{Shift}.
   383 
   384 \subsubsection*{Use flags}
   385 \vym provides various flags. You see them in the toolbar on top of the
   386 mapeditor window. (Note: Like all toolbars you can also move them to the
   387 left or the right side of the window or even detach them. Just grab the
   388 very left "dotted" part of the toolbar with your left-mouse button.) 
   389 \begin{center}
   390 	\includegraphics[width=8cm]{default-flags.png}
   391 \end{center}
   392 If you have a branch selected, you can set any number of flags by
   393 clicking them in the toolbar. The toolbar buttons change their state and
   394 always reflect the flags set in the selected branch.
   395 
   396 Presently \vym uses two kinds of flags: {\em System Flags} and {\em
   397 Standard Flags}. The standard flags are those shown in the toolbar.
   398 System flags are set by \vym to indicate e.g. that there is additional
   399 information in a note (more on this in \ref{noteeditor}). Later versions
   400 of \vym may have another kind of flags, which may be edited by the user.
   401 
   402 \subsubsection*{Images}
   403 The easiest way to add an image to a branch is by dragging it e.g. from a
   404 webbrowser to the mapeditor while a branch is selected there.
   405 
   406 You can also add a image to a branch by opening the context menu of the
   407 branch choose "Add Image". A
   408 dialog window lets you choose the image to load. 
   409 \footnote{Supported image types are: PNG, BMP, XBM, XPM and PNM. It may
   410 	also support JPEG, MNG and GIF, if specially configured during
   411 	compilation (as done when \vym is part of SUSE LINUX).}
   412 While an image is selected in the dialog, you can see a preview of the
   413 image. It is also possible to select multiple images.	
   414 
   415 You can position the image anywhere you want, just drag it with left
   416 mouse. To relink it to another branch, press \key{Shift} while moving
   417 it. To delete it, press \key{Del}. 
   418 
   419 If you right-click onto an image, a context menu will open which let's
   420 you first choose one of several image formats. Then a file dialog opens
   421 to save the image. Hint: This is used to "export" the image, it will be
   422 saved anyway in the map itself! You can also cut and
   423 copy images, but it is not possible to add objects to an image\footnote{
   424 	Images are regarded as "extra feature". It would make working with
   425 	the map much more complex if e.g. images could be linked to images.}
   426 
   427 The option \lq{\bf Use for export} \rq controls the output of exports
   428 e.g. to HTML: If set to no, the image won't appear in the {\em text}
   429 part of the output. This is useful for large images or if images are
   430 used as a kind of frame e.g. the famous cloud symbol around a part of
   431 the map. Those shouldn't appear in the middle of the text.
   432 
   433 At the moment image support is preliminary: Images will be saved
   434 together with all the other data of a map in the {\tt .vym}-file.
   435 Later versions will include more functionality like resizing the images,
   436 changing its z-value (put it into background) etc.
   437 
   438 \subsubsection*{Frames}
   439 A frame can be added to a branch by clicking with the
   440 right-mouse button.  A context menu will open, where you can choose the
   441 frame. At the moment just a rectangle resp. "No Frame" will be offered,
   442 nevertheless you can use images as frames. Have a look at the demo map
   443 {\tt todo.vym} as an example, where the mapcenter is a cloud. You can
   444 use an external drawing program like {\tt gimp} to create an image,
   445 preferable with an transparency channel, so that you can design frames
   446 which don't use a rectangular borderline, just like the cloud.
   447 
   448 
   449 \subsection{Background design}
   450 The design of the background of a map and also of the links connecting
   451 various parts of the map can be changed by
   452 \begin{itemize}
   453 	\item Selecting Format from the menu
   454 	\item Right clicking onto the canvas, which will open a context menu
   455 \end{itemize}
   456 
   457 \subsubsection*{Background color}
   458 The color is set (and also displayed) as "Set background color".
   459 
   460 \subsubsection*{Link color}
   461 Links connecting branches can be colored in one of the following ways:
   462 \begin{itemize}
   463 	\item use the color of the heading of the branch the links is
   464 	\item use {\em one} color for all links. The default color is blue.
   465 	leading to.
   466 \end{itemize}
   467 The latter can be set with "Set link color". Check or uncheck the "Use
   468 color of heading for link" option to choose one of the two designs for
   469 your map.
   470 
   471 \subsubsection*{Link style}
   472 \vym offers four different styles for the appearences of links:
   473 \begin{itemize}
   474 	\item Line
   475 	\item Parabel
   476 	\item Thick Line
   477 	\item Thick Parabel
   478 \end{itemize}
   479 The "thick" styles only draw links starting at mapcenter thick, the rest
   480 of the map is always painted "thin".
   481 
   482 
   483 \subsection{Links to other documents and webpages}
   484 \vym supports two kind of external links:
   485 \begin{itemize}
   486 	\item Document, which will be opened in an external webbrowser
   487 	\item \vym map, which will be opened in \vym itself
   488 \end{itemize}
   489 In addition to the external links there also internal ones, leading from one
   490 branch in a map toanother one. Those are called {\em XLinks} and are explained
   491 in section~\ref{xlinks}.
   492 
   493 \subsubsection*{Webbrowser}
   494 Modern Webbrowsers like {\tt konqueror} are able to display various
   495 types of files, both local or in the internet. To enter the URL of
   496 any document, right-click  onto a branch or use the Edit Menu
   497 and choose "Edit URL". Enter the path to your document (or copy and
   498 paste it from your browser). Examples for valid paths are:
   499 \begin{verbatim}
   500 	http://www.insilmaril.de/vym/index.html
   501 	file:/usr/share/doc/packages/vym/doc/vym.pdf
   502 \end{verbatim}
   503 If an URL was entered, a little globe will appear in the branch. By
   504 clicking on the globe in the toolbar or the context menu an external
   505 browser\footnote{
   506 	The browser can be changed in the Settings Menu.}
   507 will be started.
   508 \begin{center}
   509 	\includegraphics[width=0.5cm]{flag-url.png}
   510 \end{center}
   511 If you use konqueror as browser, \vym will remember the konqueror which
   512 was opened first by \vym. You can also press \key{Ctrl} and click to
   513 open the link in a new tab then.
   514 
   515 If you want to keep bookmarks in a map, select a branch where you want
   516 to add the bookmark, then simply drag the URL from your browser to the
   517 map. Also you could use an existing heading as URL: Right click onto the
   518 branch and select "Use heading for URL".
   519 
   520 \subsubsection*{\vym map}
   521 To link to to another map right click on a branch or choose "Edit \ra
   522 Enter \vym link". A file dialog opens where you can choose the map. A
   523 branch with a link is marked with 
   524 \begin{center}
   525 	\includegraphics[width=0.5cm]{flag-vymlink.png}
   526 \end{center}
   527 Clicking this flag in the toolbar or in the context menu of a branch
   528 will open the map in another tab (see \ref{tabs} for working with
   529 multiple maps). To delete an existing link, just press the "Cancel"
   530 button.
   531 
   532 Technical note: Internally \vym uses absolute paths, to avoid opening
   533 several tabs containing the same map. When a map is saved, this path is
   534 converted to a relative one (e.g. {\tt /home/user/vym.map} might become
   535 {\tt ./vym.map}. This makes it fairly easy to use multiple maps on
   536 different computers or export them to HTML in future.
   537 
   538 \subsection{Multiple maps} \label{tabs}
   539 You can work on multiple maps at the same time. Each new map is opened
   540 in another {\em tab}. The available tabs are shown just above the
   541 mapeditor. You can use the normal cut/copy/paste functions to
   542 copy data from one map to another.

   557 \section{Noteeditor} \label {noteeditor}
   558 If you want to save more text in a branch e.g. a complete email, a
   559 cooking recipe, or the whole source code of a software project, you can
   560 use the noteeditor. 
   561 \begin{center}
   562 	\includegraphics[width=8cm]{noteeditor.png}
   563 \end{center}
   564 This editor displays text associated to a branch selected in the
   565 mapeditor. To visualize that there maybe is no text yet, the noteeditor
   566 shows different background colors depending on its state:
   567 
   568 \subsection{States}
   569 Before you can type or paste text into it, you have
   570 to select a branch in the mapeditor. Note that the background color
   571 of the noteeditor indicates its state:
   572 \begin{itemize}
   573 	\item black: no branch selected
   574 	\item grey: no text entered yet
   575 	\item white: text is already available
   576 \end{itemize}	
   577 To show you in the mapeditor itself that there is a note with more
   578 information for a particular branch, a little note flag will appear next
   579 to the heading of the branch. See the lower branch on the right side:
   580 \begin{center}
   581 	\includegraphics[width=8cm]{branches-flags.png}
   582 \end{center}
   583 
   584 \subsection{Import and export notes}
   585 The note is always saved automatically within the \vym file itself.
   586 Nevertheless sometimes it is nice to import a note from an external file
   587 or write it. Use "File\ra~Import" and "File\ra~Export" to do so. 
   588 
   589 \subsection{Edit and print note}
   590 Editing works like in any simple texteditor, including undo and redo
   591 functions. You can delete the complete note by clicking the
   592 trashcan. Only the note itself is printed by clicking the printer icon.
   593 
   594 When pasting into the editor using the X11 copy\&paste mechanism, the
   595 editor will create a paragraph for each new line. Usually this is not
   596 wanted, so there you can convert all paragraphs into linebreaks by using
   597 Edit~\ra~Remove~Paragraphs or \key{ALT-X}.
   598 
   599 \subsection{RichText: Colors, paragraphs and formatted text}
   600 \vym supports formatted text (QT Rich Text) in the noteeditor since
   601 version 1.4.7.  Colors and text attributes (e.g. italic, bold) can be
   602 set with the buttons above the text.  The text itself is divided in
   603 paragraphs. For each paragraph the format can be set (e.g. centered,
   604 right). A paragraph is ended when a \key{Return} is entered. If you just
   605 want to begin a new line, press \key{CTRL-Return}.
   606 
   607 \subsection{Fonts and how to quickly switch them}
   608 The noteeditor is ment to be used for simple notes, not really as full
   609 featured text editor. Because of many requests \vym supports now
   610 formatted text in the noteeditor\footnote{
   611 	\vym uses the QRichtText format, which is basically a subset of the
   612 	formatting provided in HTML.}
   613 Two default fonts are supported which can be set in the Settings menu.
   614 One is a fixed width font, the other has variable width. The fixed font
   615 is usually used for emails, source code etc.\ while the variable font is
   616 used for simple notes, where one doesn't need fixed character widths.
   617 Both fonts can easily switched using the following symbol from the
   618 toolbar:
   619 \begin{center}
   620 	\includegraphics[width=0.5cm]{formatfixedfont.png}
   621 \end{center}
   622 In the Settings menu both fonts can be set and also which font should be
   623 used for default. 
   624 
   625 Additionally to the default fonts any font installed on your system can
   626 be used. Please note, that the chosen font also will be used for HTML
   627 exports, so you should only use fonts which are available generally.
   628 
   629 \subsection{Find text}
   630 The noteeditor itself has no Find function, use Find in the mapeditor,
   631 which will also search all notes (see \ref{findwindow}).
   632 
   633 \subsection{Paste text into note editor}
   634 Often you will paste text into the editor from another application e.g.
   635 an email. Normally \vym will generate a new paragraph for each new line.
   636 This usually is not what you want, so you can choose from the menu
   637 
   638 \subsection{Advanced actions}
   639 \subsubsection*{Edit \ra Convert subsubsections:}
   640 This turns subsubsections in selected text (or all text, if nothing is
   641 selected) into linebreaks. This is especially useful for snippets of
   642 source code.
   643 
   644 \subsubsection*{Edit \ra Join Lines:}
   645 Tries to format text, so that empty lines are used to delimit
   646 paragraphs. This is done for selected text (or all text, if nothing is
   647 selected). Especially useful for text like emails, meeting minutes etc.
   648 
   649 \section{Hello world}
   650 This section is about how \vym can interact with other applications.
   651 Many applications meanwhile can read and write their data using XML, the
   652 eXtensible Markup Language. \vym also uses XML to save its maps, see
   653 \ref{fileformat} for a more detailed description. 
   654 
   655 So if your an application understands XML, chances are good that someone
   656 could write import/export filters for \vym. Volunteers are always
   657 welcome ;-)
   658 
   659 \subsection{Import} 
   660 
   661 \subsubsection*{KDE Bookmarks}
   662 The integrated bookmark editor in KDE is somewhat limited, so why not
   663 use \vym to maintain the bookmark mess? To create a new map containing
   664 your current KDE bookmarks just choose
   665 \begin{itemize}
   666 	\item File \ra Import\ra KDE Bookmarks
   667 \end{itemize}
   668 
   669 \subsubsection*{Mind Manager}
   670 \vym has currently a very basic import filter to convert maps created by
   671 {\em Mind Manager}\footnote{Mind Manager is a professional software by
   672 Mindjet. Both names are registered trademarks by Mindjet. For more
   673 information see their website at
   674 \href{http://mindjet.de}{http://mindjet.de}} into \vym maps. Notes and
   675 pictures are not converted at the moment. You can import files with
   676 \begin{itemize}
   677 	\item File \ra Import\ra Mind Manager
   678 \end{itemize}
   679 
   680 
   681 \subsubsection*{Directory structure}
   682 \vym can read a directory structure. This is mainly for
   683 testing \vym e.g. to easily create huge maps used for benchmarks (yes,
   684 there is still room to optimize \vym ;-)
   685 
   686 \subsection{Export}
   687 \label{hideexport}
   688 Often you don't want to export the whole map, but just parts of it. For
   689 example you may have additional info you want to talk about in a
   690 presentation, while those parts should not be visible to the audience.
   691 To achieve this you can "hide" parts of the map during exports by
   692 setting the "hide in export" flag.
   693 \begin{center}
   694 	\includegraphics[width=0.5cm]{flag-hideexport.png}
   695 \end{center}
   696 You can toggle this flag in the toolbar or by pressing \key{H}.
   697 Note that there is a global option in the settings menu to toggle the
   698 use of this flag. By default the flag is enabled.
   699 
   700 \subsubsection*{Open Office}
   701 Open Office beginning with version~2 uses the so called "Open Office
   702 Document Format", which can be written by \vym. The options are
   703 currently limited, but it possible to export presentations which can be
   704 opened in Open Office Impress. By selecting
   705 \begin{itemize}
   706 	\item File \ra Export\ra Open Office
   707 \end{itemize}
   708 you get a file dialogue where you can choose the output file and the
   709 file type:
   710 \begin{center}
   711 	\includegraphics[width=12cm]{export-oo.png}
   712 \end{center}
   713 The file types represent various templates, which can be created with
   714 some manual work from an existing Open Office document. The structure of
   715 \vym map is then inserted into a template. 
   716 There are some limitations at the moment:
   717 \begin{itemize}
   718 	\item \vym can't take care of page lengths, so you have to check and
   719 	probably reedit in Open Office to avoid text running over the end of
   720 	a page
   721 	\item Images and flags are not used at the moment
   722 	\item Notes are just written as plain text, without RichText
   723 \end{itemize}
   724 Some of the templates make use of {\em sections} e.g. insert the
   725 headings of mainbranches as chapters for sections into the presentation.
   726 
   727 \subsubsection*{Image}
   728 \vym supports all image formats which are natively supported by the
   729 QT~toolkit:
   730 BMP, JPEG, PBM, PGM, PNG, PPN, XPM, and XBM.
   731 For use in websites and for sending images by email PNG is a good
   732 recommodation regarding quality and size of the image. \vym uses QTs
   733 default options for compressing the images.
   734 
   735 \subsubsection*{ASCII}
   736 Exporting an image as text is somewhat experimental at the moment. Later
   737 this will probably done using stylesheets. So the output may change in
   738 future versions of \vym.
   739 
   740 \subsubsection*{\LaTeX}
   741 \vym can generate an input file for \LaTeX. Currently this is considered
   742 as experimental, there are no options (yet). 
   743 By selecting
   744 \begin{itemize}
   745 	\item File \ra Export\ra \LaTeX 
   746 \end{itemize}
   747 you will be asked in a file dialog for the name of the output file. This
   748 file should be included in a \LaTeX document using command  
   749 \begin{verbatim}
   750 	\include{inputfile.tex}
   751 \end{verbatim}
   752 
   753 \subsubsection*{XHTML (Webpages)}
   754 
   755 This is the format you want to use to create a webpage. For an example
   756 have a look at the \vym homepage: 
   757 \href{http://www.InSilmaril.de/vym}{www.InSilmaril.de/vym}
   758 
   759 Some explanation how this works: 
   760 Before a map is exported as XHTML, it will be first written as XML into a
   761 directory (see \ref{xmlexport}). Then the external program {\tt
   762 xsltproc}\footnote{On SUSE Linux {\tt xsltproc} is installed by
   763 default.}
   764 will be called to process the XML file and generate HTML code.
   765 A dialog allows to set various options:
   766 \begin{itemize}
   767 	\item {\bf Include image:} If set, \vym will creat an image map at
   768 	the top of the HTML output. Clicking on a branch in the map will
   769 	jump to the corresponding section in the output.
   770 
   771 	\item {\bf Colored headings:}
   772 	If set to yes, \vym will color the headings in the text part  with the
   773 	same colors like in the map.
   774 	\item {\bf Show Warnings:}
   775 	If set to yes, \vym will ask before overwriting data.
   776 	\item {\bf Show output:}
   777 	This is useful mainly for debugging. It will show how the processing of
   778 	the XML file works by calling the external {\tt xsltproc}.
   779 \end{itemize}
   780 Additionally the paths to the CSS and XSL stylesheets can be set. By
   781 default on SUSE~Linux they will be in {\tt /usr/share/vym/styles}.
   782 
   783 
   784 \subsubsection*{XML} \label{xmlexport}
   785 The map is written into a directory both as an image and as XML. The
   786 directory is set in a file dialog. If the directory is not empty, you
   787 will be questioned if you risk to overwrite its contents.
   788 
   789 It is possible to export different maps into the same directory. Each
   790 file generated will have the map's name as prefix, e.g. {\tt todo.vym}
   791 becomes {\tt todo.xml}, {\tt todo.png}, {\tt todo-image-1.png} and so
   792 on. This is useful if e.g. for a website several combined maps have to
   793 be stored in the same directory.
   794 
   795 \subsubsection*{Export a part of a map}
   796 Select a branch you want to export together with its childs, then open
   797 the context menu and choose {\em Save Selection}. This will create a
   798 file with the postfix {\tt .vyp}, which is an abbreviation for \lq vym
   799 part\rq.
   800 
   801 
   802 \section{Advanced Editing}
   803 \vym offers a few shortcuts to let you work more quickly and literally
   804 to connect any branches directly.  
   805 \subsection{Modifier Modes} 
   806 Modifiers are for example the \key{Shift}- or the \key{Alt}-keys. When
   807 pressed while doing actions with the mouse, they will cause \vym to use
   808 a "modified" action. E.g. you can move branches with mouse. If
   809 \key{Ctrl} or \key{Alt}is pressed while releasing the branch, it will be
   810 added above/below the target, not as child of the target.
   811 
   812 Without a modifier pressed, the first click on a branch just selects
   813 it. For the behaviour of the \key{Ctrl} modifier there are several
   814 options, which can be set from the modifier toolbar:
   815 \begin{center}
   816 	\includegraphics[width=3cm]{modmodes.png}
   817 \end{center}
   818 The default  is to copy the color from the clicked branch to the already
   819 selected branch. In the toolbar shown above the default modifier is
   820 selected, namely to copy the color of a branch. The second modifier
   821 let's you easily copy a whole branch with a single click. The third
   822 modifier lets you create {\em xLinks}, which will be explained in the
   823 next section.
   824 
   825 \subsection{Hide links of unselected objects}
   826 Sometimes it would be useful to position a branch freely, just like a
   827 mainbranch or an image. Though this is not possible (yet) for all
   828 branches, you can use a mainbranch and hide its connecting link to the
   829 mapcenter. This can be used e.g. for legends or a collection of vymLinks
   830 pointing to other maps:
   831 \begin{center}
   832 	\includegraphics[width=9cm]{hiddenlink.png}
   833 \end{center}
   834 
   835 
   836 \subsection{XLinks} \label{xlinks}
   837 So far all the data in the \vym map has been treelike. Using xLinks you
   838 can link one branch to any other, just like attaching a rope between two
   839 branches in a real tree. This is especially useful in complex maps,
   840 where you want to have crossreferences which don't fit on the same
   841 visible area, which fits on your screen. The following example, which is
   842 part of the \vym package, still fits on one screen, but shows how data
   843 can be crosslinked. In the graphics there is a link from a task (prepare
   844 a presentation) to general information:
   845 \begin{center}
   846 	\includegraphics[width=12cm]{xlink.png}
   847 \end{center}
   848 Note that a xLink which points to a branch that is not visible (because
   849 it is scrolled), is just show as a little horizontal arrow. In the
   850 screenshot above have a look at the \lq Tuesday\rq\ branch.
   851 
   852 \subsubsection*{Create a xLink}
   853 Choose the link mode from the modifier toolbar (by clicking or pressing
   854 \key{L}). Select the branch, where the xLink should start. Press the
   855 modifier key \key{Ctrl} and simultanously click on the branch where the
   856 link should end. (The link is already drawn before you release the mouse
   857 key). If you release the mouse over a branch the xLink becomes
   858 permanent.
   859 
   860 \subsubsection*{Modify or delete a xLink}
   861 Open the context menu of a branch and select \lq Edit xLink\rq. A
   862 submenu contains all the xLinks of the branch (if there are any). They
   863 are named like the branches, where they end. Choose one and
   864 the xLink dialogue opens, where you can set color, width and also delete
   865 the xLink.
   866 
   867 \subsubsection*{Follow a xLink}
   868 In a complext \vym map it sometimes comes handy to jump to the other end
   869 of a xLink. You can do this by opening the context menu of the branch
   870 and clicking on \lq Goto xLink\rq and selecting the xLink you want to
   871 follow.
   872 
   873 
   874 
   875 \subsection{Adding and removing branches}
   876 The context menu of a branch shows some more ways to add and delete data
   877 e.g. you can delete a branch while keeping its childs. The childs become
   878 linked to the parent of the previously removed branch.
   879 Similar branches can be inserted into existing maps. For keyboard
   880 shortcuts also have a look at the context menu.
   881 
   882 \subsection{Adding a whole map or a part of a map}
   883 Select a branch where you want to add a previously saved map ({\tt .vym})or a part
   884 of a map ({\tt .vyp}) , then open
   885 the context menu and choose {\em Add \ra Import}. For the import you can
   886 choose between {\em Import Add} and {\em Import Replace}: The imported
   887 data will be added after the selection resp. replace the selection.

   890 \section{\vym on Mac OS X}
   891 \subsection{Overview}
   892 Basically there are two ways to run \vym on Macs:
   893 \subsubsection*{QT Mac Edition:}
   894 	\vym here provides the well known Mac look and feel.  \vym is
   895 	available as zipped Mac OS X application. It has been compiled and
   896 	tested in Mac~OS~10.3, but should also work on Tiger. It is using
   897 	the Mac version of Trolltechs QT library.  
   898 \subsubsection*{X11}
   899 	\vym can also be run using the Linux version, but then menus and
   900 	handling will also be those of the Linux version e.g. The menu bar
   901 	will look different. 
   902 
   903 \subsection	{Contextmenu and special keys}
   904 Most Macs unfortunatly just have a single mouse button. In order to show
   905 the context menu which usually would be opened with the right mouse
   906 button, you can click while pressing the \key{kommand}-key.
   907 
   908 Especially on Laptops some of the keys usually used on PC keyboards seem
   909 to be missing. The QT-Mac Edition of \vym has its own keyboard
   910 shortcuts. To find the shortcuts just have a look at all the menu
   911 entries, the shortcut is visible next to an entry. Toolbar buttons also
   912 may have shortcuts, just position the mouse pointer over a button and
   913 wait for the little help window to appear. 
   914 
   915 \subsection {Viewing external links}
   916 \vym on Mac uses the system call {\tt /usr/bin/open} to view links.
   917 Mac~OS determines automatically if the link is a pdf or www page and
   918 opens the right browser.
   919 
   920 
   921 \begin{appendix}
   922 
   923 \section{Starting \vym}
   924 \subsection{Path to ressources}
   925 \vym will try to find its ressources (images, stylesheets, filters,
   926 etc.) in the following places:
   927 \begin{enumerate}
   928 	\item Path given by the environment variable {\tt VYMHOME}.
   929 	\item If called with the local option (see \ref{options} below),
   930 	      \vym will look for its data in the current directory.
   931 	\item {\tt /usr/share/vym}
   932 	\item {\tt /usr/local/share/vym}
   933 \end{enumerate}
   934 
   935 \subsection{Command line options} \label{options}
   936 \vym has the following options:
   937 \begin{center}
   938 \begin{tabular}{ccp{8cm}}\\ 
   939 \bf Option	& \bf Comment & \bf Description \\ \hline
   940 v & version & Show version ov \vym\\
   941 l & local	& Use local paths to stylesheets, translations, icons, 
   942               etc. instead of system paths. Useful for testing\\
   943 h & help	& Show help\\
   944 q & quit	& Quit immediatly after startup. Useful for benchmarks.\\
   945 \end{tabular}
   946 \end{center}
   947 You can also give several filenames at the commandline to let \vym open
   948 several maps at once.
   949  
   950 \section{Contributing to \vym}
   951 So far I'd say I have written 98\% of the code on my own. No surprise,
   952 that \vym exactly fits my own needs. Nevertheless I would like to
   953 encourage all users of  \vym to contribute. Maybe not only with feature
   954 requests, but also with code, new import/export filters, translations
   955 etc. In this appendix I'll try to show how easy it is to expand the
   956 things you can do already with \vym. I really look forward to hear from
   957 you!
   958 
   959 \subsection{Getting help}
   960 
   961 \subsubsection*{Frequently asked questions}
   962 Please refer to the FAQ available on the \vym website:
   963 \begin{center}
   964 \href{http://www.InSilmaril.de/vym/faq.html}{http://www.InSilmaril.de/vym/faq.html}
   965 \end{center}
   966 
   967 \subsubsection*{Mailinglists}
   968 There are two mailinglists: {\tt vym-forum} is the \vym users forum to
   969 discuss various questions, while {\tt vym-devel} is intended for people
   970 interested in contributing to \vym. You can view the archives and
   971 subscribe at
   972 \begin{center}
   973 \href{https://sourceforge.net/mail/?group_id=127802}{https://sourceforge.net/mail/?group\_id=127802}
   974 \end{center}
   975 
   976 \subsubsection*{Contacting the author}\label{author}
   977 Especially for support questions please try the mailinglists first. If
   978 everything else fails you can contact the Uwe Drechsel at
   979 \begin{center}
   980 \href{mailto:vym@InSilmaril.de}{vym@InSilmaril.de}
   981 \end{center}
   982 
   983 
   984 
   985 \subsection{How to report bugs}
   986 Though Sourceforge has its own bugreporting system, I'd rather prefer if
   987 you contact me directly (see \ref{author}) or even better: You can file
   988 a bugreport in Bugzilla, the bugtracking system of openSUSE:
   989 \begin{center}
   990 \href{http://en.opensuse.org/Submit_a_bug}{http://en.opensuse.org/Submit\_a\_bug}
   991 \end{center}
   992 I build \vym regulary for openSUSE, so you may report it against a
   993 recent version there, even if you  use another Operating System.
   994 Please don't forget to tell 
   995 \begin{itemize}
   996 	\item the exact steps needed to reproduce the bug
   997 	\item the version and build date of \vym (see the Help \ra About
   998 	\vym)
   999 	\item hardware and Operating System
  1000 \end{itemize}
  1001 
  1002 \subsection{Compiling from the sources}
  1003 \subsubsection{Getting the sources} \label{getsources}
  1004 You find the latest version of \vym at the project site:
  1005 \begin{center}
  1006 \href{https://sourceforge.net/projects/vym/}{https://sourceforge.net/projects/vym/}
  1007 \end{center}
  1008 There you can check them out of the source repository (CVS):\\
  1009 
  1010 \begin{verbatim}
  1011 cvs -d:pserver:anonymous@cvs.sf.net:/cvsroot/vym checkout code
  1012 \end{verbatim}
  1013 
  1014 \subsubsection{The Qt toolkit}
  1015 Qt is C++ toolkit for multiplatform GUI and application development. It
  1016 provides single-source portability across MS~Windows, Mac~OS~X, Linux
  1017 ans all major commercial Unix variants. Qt is also available for
  1018 embedded devices. Qt is a Trolltech product. For more information see 
  1019 \begin{center}
  1020 \href{http://www.trolltech.com/qt/}{www.trolltech.com/qt} 
  1021 \end{center}
  1022 
  1023 
  1024 \subsubsection{Compiling \vym }
  1025 Make sure you have installed your Qt environment properly, see the Qt
  1026 documentation for details. You need to have the Qt command {\tt qmake}
  1027 in your {\tt PATH}-environment, then run
  1028 \begin{verbatim}
  1029 qmake
  1030 make  
  1031 make install
  1032 \end{verbatim}
  1033 The last command {\tt make install} needs root-permissions. Of course it
  1034 may be omitted, if you just want to test \vym.
  1035 
  1036 %\subsubsection*{Compiling \vym on Macs}
  1037 %TODO
  1038 
  1039 \subsection{\vym file format} \label{fileformat}
  1040 \vym maps usually have the postfix "{\tt .vym}" and represent a
  1041 compressed archive of data. If you want to have a
  1042 closer look into the data structure map called "mapname.vym", 
  1043 just uncompress the map manually using
  1044 \begin{verbatim}
  1045 	unzip mapname.vym
  1046 \end{verbatim}
  1047 This will create directories named {\tt images} and {\tt flags} in your
  1048 current directory and also the map itself, usually named {\tt
  1049 mapname.xml}.
  1050 The XML structure of \vym is pretty self explaining, just have a look at
  1051 {\tt mapname.xml}.
  1052 
  1053 This XML file can be loaded directly into \vym, it does not have to be
  1054 compressed. If you want to compress all the data yourself, use
  1055 \begin{verbatim}
  1056 	zip -r mapname.vym .
  1057 \end{verbatim}
  1058 to compress all data in your current directory.
  1059 
  1060 \subsection{New features}
  1061 There are lots of features which might find their way into \vym.
  1062 Together with \vym you should have received a directory with several
  1063 maps e.g. on SUSE~LINUX this is
  1064 \begin{center}
  1065 	{\tt /usr/share/doc/packages/vym/demos}
  1066 \end{center}
  1067 where you find the map {\tt todo.vym}. It lists quite a lot of things to
  1068 be done in future. If you have more ideas, contact the development team
  1069 at
  1070 {\tt vym-devel@lists.sourceforge.net}.
  1071 
  1072 
  1073 \subsection{New languages support}
  1074 In order to add a new language to \vym you need 
  1075 the sources (see \ref{getsources}) and
  1076 an installation of Trolltechs QT. A part of QT are the development
  1077 tools, from those tools especially the translation tool "Linguist" is
  1078 needed. 
  1079 
  1080 In some Linux distributions the development tools are in an extra package, e.g. on SUSE LINUX you should have installed:
  1081 \begin{verbatim}
  1082     qt3-devel.rpm
  1083     qt3-devel-doc.rpm
  1084     qt3-devel-tools.rpm
  1085     qt3-man.rpm
  1086 \end{verbatim}
  1087 If you don't have QT in your system, you can get it from 
  1088 	\href{http://www.trolltech.com}{http://www.trolltech.com} Once you
  1089 	are able to compile vym yourself, you can translate the text in vym
  1090 	itself by performing the following steps:
  1091 \begin{itemize}
  1092 	\item Let's assume now your encoding is "NEW" instead of for example
  1093 	"de" for german or "en" for english
  1094 	
  1095 	\item Copy the file {\tt lang/vym\_en.ts} to l{\tt ang/vym\_NEW.ts} (The code
  1096 	itself contains the english version.)
  1097 		
  1098 	\item Add {\tt lang/vym\_NEW.ts} to the TRANSLATIONS section of vym.pro
  1099 
  1100 	\item Run Linguist on {\tt vym\_NEW.ts} and do the translation
  1101 
  1102 	\item Run {\tt lrelease} to create {\tt vym\_NEW.qm}
  1103 
  1104 	\item Do a make install to install the new vym and check your translation
  1105 \end{itemize}
  1106 
  1107 If you feel brave, you can also translate the manual. It is written in
  1108 LaTeX, you just have to change the file tex/vym.tex. (Linguist and QT
  1109 are not needed, but it is useful to know how to work with LaTeX and esp.
  1110 pdflatex to create the PDF.) 
  1111 
  1112 Please mail me every translation you have done. I can also give you a
  1113 developer access to the project, if you want to provide translations
  1114 regulary.  
  1115 
  1116 \subsection{New export/import filters}
  1117 \vym supports various kinds of filters. Data can be written directly,
  1118 inserted into templates or it can be written as XML data and then
  1119 processed by XSL transformations. 
  1120 
  1121 Most of the import/export functionality is available in the classes
  1122 ImportBase and ExportBase and subclasses. All of them can be found in
  1123 {\tt imports.h} and {\tt exports.h}.
  1124 
  1125 \subsubsection*{Direct import/export}
  1126 An example for a direct export is the XML export. This method touches
  1127 the implementation of nearly every object of \vym, so whenever possible
  1128 you should better use a XSL transformation instead.
  1129 
  1130 If you still want to know how it is done, start looking at 
  1131 {\tt MapEditor::saveToDir} in {\tt mapeditor.cpp}.
  1132 
  1133 \subsubsection*{Templates}
  1134 Templates have been introduced to export to opendoc format used e.g. by
  1135 Open~Office. While I read the spec ($>$ 500 pages) about the format\footnote{
  1136 \href{http://www.oasis-open.org/}{http://www.oasis-open.org/}}\ 
  1137 I had the feeling that I did not want to write the export from scratch. 
  1138 It would be too complex to adapt the styles to your own wishes, e.g. the
  1139 layout.
  1140 
  1141 Instead I analyzed existing Open~Office documents. I found out that
  1142 there are lots of redundant bits of information in a standard
  1143 presentation, for example each list item is contained in its own list.
  1144 In the end I came up with the default presentation style, which still
  1145 could be simplified, just in case you have free time\ldots
  1146 
  1147 The existing templates are still work in progress, before you spent too
  1148 much time developing your own style, please contact me.  Basically the
  1149 following steps are needed to build your own style:
  1150 \begin{enumerate}
  1151 	\item Create an example in Open Office. Use a title, authors name,
  1152 	page heading etc.\ which you can easily grep for in the output file.
  1153 	
  1154 	\item Unzip  the Open Office document into a directory.
  1155 
  1156 	\item The main file is called {\tt content.xml}. All data is in one
  1157 	single line. You can split the XML tags using the script {\tt
  1158 	scripts/niceXML}, which is part of the \vym distribution.
  1159 
  1160 	\item Copy the output of {\tt niceXML} to {\tt
  1161 	content-template.xml}.
  1162 
  1163 	\item Looking closer you will find lots of unused definitions, for
  1164 	example of styles. You can delete or simply ignore them.
  1165 
  1166 	\item Try to find your title, authors name. \vym will replace the
  1167 	following strings while exporting:
  1168 	\begin{center}
  1169 	\begin{tabular}{lp{4cm}}
  1170 		{\tt <!-- INSERT TITLE -->}		& title of map \\
  1171 		{\tt <!-- INSERT AUTHOR-->	}	& author \\
  1172 		{\tt <!-- INSERT COMMENT -->}	& comment \\
  1173 		{\tt <!-- INSERT PAGES-->}		& content of map \\
  1174 	\end{tabular}
  1175 	\end{center}
  1176 	The content itself is generated in a similar way by inserting lists
  1177 	into {\tt page-template}. Here the following substitutions are made:
  1178 	\begin{center}
  1179 	\begin{tabular}{lp{7cm}}
  1180 		{\tt <!-- INSERT PAGE HEADING-->}		& heading of a page
  1181 		(mainbranch or child of mainbranch, depending on the use of
  1182 		sections) \\
  1183 		{\tt <!-- INSERT LIST -->	}	& all childs of the branch above \\
  1184 	\end{tabular}
  1185 	\end{center}
  1186 \end{enumerate}
  1187 Currently images are exported and notes just will appear as text
  1188 without formatting and colors.
  1189 
  1190 
  1191 
  1192 
  1193 \subsubsection*{XSL Transformation}
  1194 \vym uses XSL transformations while exporting (e.g. XHTML) and importing
  1195 data (e.g. KDE bookmarks). There is a little code needed to provide the
  1196 GUI, the rest is done using the {\tt .xsl} stylesheet and calling the
  1197 {\tt xsltproc} processor, which is part of libxslt, the XSLT
  1198 C  library  for  GNOME.
