 \section{Introduction}

 \subsection{What is a \vym map?}

 A \vym map (in short words {\em map}) is a tree like structure:

 \begin{center}

 	\includegraphics[width=12cm]{example1.png}

 \end{center}

 Such maps can be drawn by hand on paper or a flip chart and help to

 structure your thoughs. While a tree like structure like above can be

 drawn by hand or any drawing software \vym offers

 much more features to work with such maps. \vym is not another drawing

 software, but a tool to store and modify information in an intuitive

 way. For example you can reorder parts of the map by pressing a key or

 add various information like a complete email by a simple mouse click.

 \subsection{Why should I use maps? Time, Space and your Brain.}

 \subsubsection*{Space}

 A map can concentrate a very complex content on little space e.g. a

 piece of paper. It helps to use both sides of your brain: the logical

 side and also your creative side (e.g. by using pictures, colors and

 keywords in a map, so called {\em anchors}).  It is a technique to

 organize the way you think: It can help you by developing, sorting and

 memorizing your thoughts. 

 \subsubsection*{Time}

 Because you just use keywords and drawings, it is much faster than good

 old fashioned notes. Your brain memorizes things by associating them to

 other things -- a map makes use of those connections and stimulates

 new asccociations. 

 \subsubsection*{Your Brain}

 In 1960 the Prof. {\sc Roger Sperry} discovered that both hemispheres

 of the human brain have different tasks (of course both of them

 basically {\em can} do the same): The left side is specialised in 

 \begin{itemize}

    \item verbal speech and writing 

    \item numbers

    \item logical thinking

    \item analyzing and details

    \item science

    \item linear thinking

    \item concept of time

 \end{itemize}

 while the right side of the human brain is specialised in

 \begin{itemize}

     \item body language

     \item visual thinking, day dreams

     \item intuition and emotion

     \item overview of things

     \item creativity

     \item art, music, dancing

     \item non-linear thinking, connecting things

     \item spatial awareness

 \end{itemize}    

 In our science oriented society we have learned to mainly rely on our

 left side of the brain, the "rational" one. In other cultures,

 especially like the native americans and other "old" cultures, the right

 side is much more important. maps are just one way to stimulate the

 other side and make use of additional ressources we all have.

 \subsection{Where could I use a map?}

 Here are some examples, how you can use those maps

 \begin{itemize}

     \item to prepare articles, papers, books, talks, \ldots

     \item to sort complex data

     \item to memorize facts, persons, vocabulary, \ldots

     \item to sort emails, files and bookmarks on your computer

     \item to moderate conferences

 \end{itemize}

 \subsection{What you shouldn't do with a map...}

 A map drawn by somebody shows the way the author thinks. There is

 no right or wrong in the way it is drawn, so there is no way to critize

 it. "It is, what it is" ({\sc F.~Lehmann}).

 %\section{Tutorials}

 %TODO

 \section{Concept}

 %TODO may add a general introduction here...

 \vym uses two windows: an editor for the map itself and another one for

 notes, which are part of the map. Let's call them {\em mapeditor} and

 {\em noteeditor}: 

 \begin{center}

 	\includegraphics[width=8cm]{windows.png}

 \end{center}

 Usually you will work in the {\em mapeditor} by just adding new

 branches, moving around and reordering them. The various ways to do this

 will be explained in \ref{mapeditor}. You can store additional

 information e.g. the content of a email easily in a {\em branch}: Just

 type or copy\&paste it into the {\em noteeditor}. Working with notes is

 explained in \ref{noteeditor}

 The map itself has always a {\em mapcenter}.  The

 mapcenter has {\em branches} just like the trunk of a tree. Each branch

 in turn may have branches again.

 \begin{center}

 	\includegraphics[width=10cm]{branches.png}

 \end{center}

 We will call a branch directly connected to the mapcenter a {\em

 mainbranch}, because it determines the position of all its child

 branches.

 The mapcenter and the branches all have a {\em heading}. This is the

 text you see in the mapeditor. Usually it should just be one or a few

 words, so that one can easily keep track of the whole map.

 In the toolbar above the mapeditor you see various symbols.

 \begin{center}

 	\includegraphics[width=8cm]{default-flags.png}

 \end{center}

 These are called {\em flags} and can be used to mark branches in the

 map, e.g. if something is important or questionable. 

 There are also more flags set by \vym automatically to show additional

 information, e.g. when a  exists for a  particular branch.

 \section{Mapeditor} \label {mapeditor}

 \subsection{Start a new map}

 After \vym is started two windows will open: the mapeditor and the

 noteditor. Usually you will work in both windows, but at the moment we

 will just need the mapeditor. 

 Select the mapcenter "New map" in the middle of the mapeditor by

 left-clicking with the mouse. It will turn yellow to show that is

 selected. There are several ways to add a new branch to the center:

 \begin{itemize}

 	\item Using the mouse: Open the context meny by clicking with the

 	right mouse button (CTRL-Click on Mac) onto the

 	mapcenter and choose Add \ra Add as child

 	\item Press \key{Ins} or \key{A}

 \end{itemize}

 A new branch will appear and you will be able to type the heading of the

 branch. Finish adding the new branch by pressing \key{Enter}.

 %tipp

 Sometimes it comes handy to add a new branch above or below the current

 one. Use \key{Ins} together with \key{Shift} or \key{Ctrl}. 

 \subsection{Navigate through a map}

 \subsubsection*{Select branches}

 To select branches you can use the left button of your mouse or also the

 arrow keys. Depending on the {\em orientation} of a branch type

 \key{\la} or \key{\ra} to get nearer to the mapcenter or deeper

 down into the branches. Within a set of branches, let's call them a 

 {\em subtree}, you can use \key{\ua} and \key{\da} to go up and down. You can

 also use \key{Pos1} and \key{End} to select the first and last branch.

 \subsubsection*{Zoom a map}

 While adding more and more branches the size of the map may become

 bigger than the mapeditor window. You can use the scrollbars on the

 right and the bottom of your mapeditor window to scroll, but it is

 easier to just scroll using the left mouse button: Click onto the {\em

 canvas} itself, the empty space somewhere between the branches. The

 mouse pointer will change from an arrow to a hand, now move the visible

 part of the map to show the desired part.

 If you select branches using the arrow keys, the map will scroll

 to ensure that the selected branch is always visible.

 Working with huge maps, the {\em zoom}-function comes in handy: You can

 use 

 \begin{itemize}

 	\item from the menu View \ra Zoom

 	\item the toolbar buttons 

 		\begin{center}

 			\includegraphics[width=3cm]{zoom-buttons.png}

 		\end{center}	

 \end{itemize}	

 The crossed magnifying lens resets the zoomed view to its original size.

 \subsubsection*{Find Function} \label{findwindow}

 With huge maps there is the need to have a

 find function. Choose Edit \ra Find to open the Find Window:

 \begin{center}

 	\includegraphics[width=6cm]{find-window.png}

 \end{center}	

 The text you enter here will be searched in all the headings and also in

 notes. Everytime you press the "Find"-button it will look for the next

 occurence, which then will be selected automatically. If the search

 fails, there will appear a short message "Nothing found" or a few

 seconds in the {\em statusbar} on the bottom of the mapeditor.

 \subsubsection*{Scroll a part of the map}

 A very big subtree of a map e.g. a branch with hundreds of childs makes

 it very hard to keep an overview over the whole map. You can hide all

 the childs of a branch by {\em scrolling} it -- this function is also

 often called {\em folding}. Think of the whole subtree as painted onto a

 big newspaper. You can scroll the paper to a small roll, leaving just

 the headline readable.

 To scroll or unscroll a branch and its childs, press the

 \begin{itemize}

 	\item \key{Scroll} key or  \key{S}

 	\item press the middle-mouse button or

 	\item choose the little scroll from the toolbar.

 \end{itemize}

 If you select parts of a scrolled branch e.g. using the find function or

 by using the arrow-keys, it will unscroll temporary. This is shown as a

 scroll with a little hour glass. If the temporary unscrolled part is not

 longer needed, it will be hidden again automatically. It is also

 possible to unscroll all branches using "Edit\ra Unscroll all scrolled

 branches".

 \subsection{Modify and move branches}

 \subsubsection*{Modify the heading of a branch}

 You can edit the heading by selecting the branch and then

 \begin{itemize}

 	\item pressing \key{Enter}

 	\item double-clicking with left mouse.

 \end{itemize}

 Just type the new heading (or edit the old one) and press \key{Enter}.

 \subsubsection*{Move a branch}

 The easiest way to move a branch is to select it with left-mouse and

 drag it to the destination while keeping the mouse button pressed.

 Depending on the branch  it will be

 \begin{itemize}

 	\item moved to the destination or

 	\item {\em linked} to a new {\em parent} (mapcenter or branch)

 \end{itemize}

 If you drag the branch over another one or over the mapcenter, you will

 notice that the  link connecting it to the old parent will be changed to

 lead to the  new parent which is now under your mousepointer. 

 If you release the button now, the branch will be relinked.

 If you release the button in the middle of nowhere, the result will

 depend on the type of branch you are releasing:

 \begin{itemize}

 	\item A mainbranch is directly connected to the mapcenter.

 		It will stay on its new position.

 	\item An ordinary branch will "jump" back to its original position.	

 \end{itemize}

 Thus you can easily rearrange the layout of the mainbranches to avoid

 overlapping of their subtrees.

 There is another convenient way to move branches, especially if you want

 to {\em reorder} a subtree: You can move a branch up or down in a

 subtree by

 \begin{itemize}

 	\item pressing \key{\ua} and \key {\da}

 	\item selecting Edit \ra Move branch

 	\item clicking on the toolbar buttons:

 		\begin{center}

 			\includegraphics[width=1.5cm]{move-buttons.png}

 		\end{center}	

 \end{itemize}

 %tipp

 There is yet another way to move branches: If you press \key{Shift} or

 \key{Ctrl} while moving with the mouse, the branch will be added above

 or below the one the mouse pointer is over. This helps also to reorder a

 map.

 \subsection{The right side of your brain - colors and images}

 \subsubsection*{Change color of a heading}

 You can also use colors to put more information into a map, e.g. use

 red, green and more colors to prioritize tasks. Again you can

 \begin{itemize}

 	\item use the menu and choose e.g Format \rq Set Color

 	\item use the toolbar

 		\begin{center}

 			\includegraphics[width=3cm]{color-buttons.png}

 		\end{center}	

 \end{itemize}

 The first button (black in the graphic above) shows the actual color.

 Clicking on it let's you choose another color. You can also "pick"

 another color by selecting a branch with the desired color and using the

 "pick color" button. Both of the buttons showing a bucket actually put

 the current color to the selected branch. While the first one just

 colors the heading of the selection, the last one also colors all the

 childs of the selected branch.

 %tipp

 A very useful function is the "copy color" using the mouse: Select the

 branch which should get the new color, then press \key{Ctrl} and

 simultanously click with left-mouse on another branch to copy its color

 to the first one. Here the childs of the selection also will get the new

 color, if you just want to color the selection itself, additionally

 press \key{Shift}.

 \subsubsection*{Use flags}

 \vym provides various flags. You see them in the toolbar on top of the

 mapeditor window. (Note: Like all toolbars you can also move them to the

 left or the right side of the window or even detach them. Just grab the

 very left "dotted" part of the toolbar with your left-mouse button.) 

 \begin{center}

 	\includegraphics[width=8cm]{default-flags.png}

 \end{center}

 If you have a branch selected, you can set any number of flags by

 clicking them in the toolbar. The toolbar buttons change their state and

 always reflect the flags set in the selected branch.

 Presently \vym uses two kinds of flags: {\em System Flags} and {\em

 Standard Flags}. The standard flags are those shown in the toolbar.

 System flags are set by \vym to indicate e.g. that there is additional

 information in a note (more on this in \ref{noteeditor}). Later versions

 of \vym may have another kind of flags, which may be edited by the user.

 \subsubsection*{Images}

 You can add a image to a branch or the mapcenter by clicking with the

 right-mouse button. A context menu will open, choose "Add Image". A

 dialog window lets you choose the image to load. 

 \footnote{Supported image types are: PNG, BMP, XBM, XPM and PNM. It may

 	also support JPEG, MNG and GIF, if specially configured during

 	compilation (as done when \vym is part of SUSE LINUX).}

 While an image is selected in the dialog, you can see a preview of the

 image.	

 You can position the image anywhere you want, just drag it with left

 mouse. To relink it to another branch, press \key{Shift} while moving

 it. To delete it, press \key{Del}. 

 If you right-click onto an image, a context menu will open which let's

 you first choose one of several image formats. Then a file dialog opens

 to save the image. Hint: This is used to "export" the image, it will be

 saved anyway in the map itself! You can also cut and

 copy images, but it is not possible to add objects to an image\footnote{

 	Images are regarded as "extra feature". It would make working with

 	the map much more complex if e.g. images could be linked to images.}

 The option \lq{\bf Use for export} \rq controls the output of exports

 e.g. to HTML: If set to no, the image won't appear in the {\em text}

 part of the output. This is useful for large images or if images are

 used as a kind of frame e.g. the famous cloud symbol around a part of

 the map. Those shouldn't appear in the middle of the text.

 At the moment image support is preliminary: Images will be saved

 together with all the other data of a map in the {\tt .vym}-file.

 Later versions will include more functionality like resizing the images,

 changing its z-value (put it into background) etc.

 \subsubsection*{Frames}

 A frame can be added to a branch by clicking with the

 right-mouse button.  A context menu will open, where you can choose the

 frame. At the moment just a rectangle resp. "No Frame" will be offered,

 nevertheless you can use images as frames. Have a look at the demo map

 {\tt todo.vym} as an example, where the mapcenter is a cloud. You can

 use an external drawing program like {\tt gimp} to create an image,

 preferable with an transparency channel, so that you can design frames

 which don't use a rectangular borderline, just like the cloud.

 \subsection{Background design}

 The design of the background of a map and also of the links connecting

 various parts of the map can be changed by

 \begin{itemize}

 	\item Selecting Format from the menu

 	\item Right clicking onto the canvas, which will open a context menu

 \end{itemize}

 \subsubsection*{Background color}

 The color is set (and also displayed) as "Set background color".

 \subsubsection*{Link color}

 Links connecting branches can be colored in one of the following ways:

 \begin{itemize}

 	\item use the color of the heading of the branch the links is

 	\item use {\em one} color for all links. The default color is blue.

 	leading to.

 \end{itemize}

 The latter can be set with "Set link color". Check or uncheck the "Use

 color of heading for link" option to choose one of the two designs for

 your map.

 \subsubsection*{Link style}

 \vym offers four different styles for the appearences of links:

 \begin{itemize}

 	\item Line

 	\item Parabel

 	\item Thick Line

 	\item Thick Parabel

 \end{itemize}

 The "thick" styles only draw links starting at mapcenter thick, the rest

 of the map is always painted "thin".

 \subsection{Link to other documents}

 Presently \vym supports two kind of links:

 \begin{itemize}

 	\item Document, which will be opened in an external webbrowser

 	\item \vym map, which will be opened in \vym itself

 \end{itemize}

 \subsubsection*{Webbrowser}

 Modern Webbrowsers like {\tt konqueror} are able to display various

 types of files, both local or in the internet. To enter the URL of

 any document, right-click  onto a branch or use the Edit Menu

 and choose "Edit URL". Enter the path to your document (or copy and

 paste it from your browser). Examples for valid paths are:

 \begin{verbatim}

 	http://www.insilmaril.de/vym/index.html

 	file:/usr/share/doc/packages/vym/doc/vym.pdf

 \end{verbatim}

 If an URL was entered, a little globe will appear in the branch. By

 clicking on the globe in the toolbar or the context menu an external

 browser\footnote{

 	The browser can be changed in the Settings Menu.}

 will be started.

 \begin{center}

 	\includegraphics[width=0.5cm]{flag-url.png}

 \end{center}

 If you want to keep bookmarks in a map, you may want to copy the heading

 as URL: Right click onto the branch and select "Use heading for URL".

 \subsubsection*{\vym map}

 To link to to another map right click on a branch or choose "Edit \ra

 Enter \vym link". A file dialog opens where you can choose the map. A

 branch with a link is marked with 

 \begin{center}

 	\includegraphics[width=0.5cm]{flag-vymlink.png}

 \end{center}

 Clicking this flag in the toolbar or in the context menu of a branch

 will open the map in another tab (see \ref{tabs} for working with

 multiple maps). To delete an existing link, just press the "Cancel"

 button.

 Technical note: Internally \vym uses absolute paths, to avoid opening

 several tabs containing the same map. When a map is saved, this path is

 converted to a relative one (e.g. {\tt /home/user/vym.map} might become

 {\tt ./vym.map}. This makes it fairly easy to use multiple maps on

 different computers or export them to HTML in future.

 \subsection{Multiple maps} \label{tabs}

 You can work on multiple maps at the same time. Each new map is opened

 in another {\em tab}. The available tabs are shown just above the

 mapeditor. You can use the normal cut/copy/paste functions to

 copy data from one map to another.

 \section{Noteeditor} \label {noteeditor}

 If you want to save more text in a branch e.g. a complete email, a

 cooking recipe, or the whole source code of a software project, you can

 use the noteeditor. Since version 1.4.7 \vym supports formatted text in

 the noteeditor.

 \subsubsection*{States}

 Before you can type or paste text into it, you have

 to select a branch in the mapeditor. Note that the background color

 of the noteeditor indicates its state:

 \begin{itemize}

 	\item black: no branch selected

 	\item grey: no text entered yet

 	\item white: text is already available

 \end{itemize}	

 To show you in the mapeditor itself that there is a note with more

 information for a particular branch, a little note flag will appear next

 to the heading of the branch. See the lower branch on the right side:

 \begin{center}

 	\includegraphics[width=8cm]{branches-flags.png}

 \end{center}

 \subsubsection*{Import and export notes}

 The note is always saved automatically within the \vym file itself.

 Nevertheless sometimes it is nice to import a note from an external file

 or write it. Use "File\ra~Import" and "File\ra~Export" to do so. 

 \subsubsection*{Edit and print note}

 Editing works like in any simple texteditor, including undo and redo

 functions. You can delete the complete note by clicking the

 trashcan. Only the note itself is printed by clicking the printer icon.

 When pasting into the editor using the X11 copy\&paste mechanism, the

 editor will create a paragraph for each new line. Usually this is not

 wanted, so there you can convert all paragraphs into linebreaks by using

 Edit~\ra~Remove~Paragraphs or \key{ALT-X}.

 \subsubsection*{Fonts}

 The noteeditor is ment to be used for simple notes, not really as full

 featured text editor. Because of many requests \vym supports now

 formatted text in the noteeditor\footnote{

 	\vym uses the QRichtText format, which is basically a subset of the

 	formatting provided in HTML.}

 Two default fonts are supported which can be set in the Settings menu.

 One is a fixed width font, the other has variable width. The fixed font

 is usually used for emails, source code etc.\ while the variable font is

 used for simple notes, where one doesn't need fixed character widths.

 Both fonts can easily switched using the following symbol from the

 toolbar:

 \begin{center}

 	\includegraphics[width=0.5cm]{formatfixedfont.png}

 \end{center}

 In the Settings menu both fonts can be set and also which font should be

 used for default. 

 Additionally to the default fonts any font installed on your system can

 be used. Please note, that the chosen font also will be used for HTML

 exports, so you should only use fonts which are available generally.

 \subsubsection*{Colors and formatted text}

 Colors and text attributes (e.g. italic, bold) can 

 be set with the buttons above the text. 

 The text itself is divided in paragraphs. For each paragraph the format

 can be set (e.g. centered, right). A paragraph is ended when a

 \key{Return} is entered. If you just want to begin a new line, press

 \key{CTRL-Return}.

 \subsubsection*{Finding text}

 The noteeditor itself has no Find function, use Find in the mapeditor,

 which will also search all notes (see \ref{findwindow}).

 \subsubsection*{Pasting text into note editor}

 Often you will paste text into the editor from another application e.g.

 an email. Normally \vym will generate a new paragraph for each new line.

 This usually is not what you want, so you can choose from the menu

 \paragraph{Edit \ra Convert Paragraphs:}

 This turns paragraphs in selected text (or all text, if nothing is

 selected) into linebreaks. This is especially useful for snippets of

 source code.

 \paragraph{Edit \ra Join Lines:}

 Tries to format text, so that empty lines are used to delimit

 paragraphs. This is done for selected text (or all text, if nothing is

 selected). Especially useful for text like emails, meeting minutes etc.

 \section{Hello world}

 \vym can export its maps in various formats and can import data from

 outside (though import is still limited at the moment).

 \subsection{Export}

 The format in which the map will be exported can be chosen with

 \begin{itemize}

 	\item File \ra Export \ra {\em format}

 \end{itemize}

 \vym offers both HTML and ASCII export.

 \subsubsection*{Image}

 \vym supports all image formats which are natively supported by the

 QT~toolkit:

 BMP, JPEG, PBM, PGM, PNG, PPN, XPM, and XBM.

 For use in websites and for sending images by email PNG is a good

 recommodation regarding quality and size of the image. \vym uses QTs

 default options for compressing the images.

 \subsubsection*{ASCII}

 Exporting an image as text is somewhat experimental at the moment. Later

 this will probably done using stylesheets. So the output may change in

 future versions of \vym.

 \subsubsection*{HTML}

 Before a map is exported as HTML, it will be first written as XML into a

 directory (see \ref{xmlexport}). Then the external program {\tt

 xsltproc}\footnote{On SUSE Linux {\tt xsltproc} is installed by

 default.}

 will be called to process the XML file and generate HTML code.

 %A script then will transform the XML

 %version. 

 A dialog allows to set various options:

 \begin{itemize}

 	\item {\bf Include image:} If set, \vym will creat an image map at

 	the top of the HTML output. Clicking on a branch in the map will

 	jump to the corresponding section in the output.

 	\item {\bf Colored headings:}

 	If set to yes, \vym will color the headings in the text part  with the

 	same colors like in the map.

 	\item {\bf Show Warnings:}

 	If set to yes, \vym will ask before overwriting data.

 	\item {\bf Show output:}

 	This is useful mainly for debugging. It will show how the processing of

 	the XML file works by calling the external {\tt xsltproc}.

 \end{itemize}

 Additionally the paths to the CSS and XSL stylesheets can be set. By

 default on SUSE~Linux they will be in {\tt /usr/share/vym/styles}.

 %\paragraph{WIKI style:} This is very useful for easy design of webpages.

 %Here is a short overview:

 %\begin{verbatim}

 %Lines:

 %	+ Big headlines start with the '+' character.

 %	- Small headlines start with the '-' character.

 %	  Normal text doesn't have any starting notation.

 %	! Notes start with an exclamation.

 %	. Indented text starts with a dot.

 %	? Questions start with a question-mark, and

 %	= Answers starts with the equal-sign.

 %	* Points for a item-list

 %	# clues

 %	

 %Links:

 %	use '{...}' or '{(vym homepage) http://www.insilmaril.de/vym/}'

 %	for external links.

 %	

 %Markup:

 %	|This is bold| text, while 

 %	|/this text is italic|, 

 %	|*this is pre-formatted|, and 

 %	|!this is a note|

 %\end{verbatim}

 %

 %\paragraph{Show output:} This is used for debugging. \vym uses an

 %the external script {\tt vym2html.sh} to preprocess the XML-data. Then

 %\vym calls {\tt xsltproc} to generate the HTML page by using various

 %{\tt .xsl} stylesheets and {\tt wireframe.css}. If you run into problems

 %here, changing paths in {\tt $\sim$/.qt/vymrc} might help.

 \subsubsection*{XML} \label{xmlexport}

 The map is written into a directory both as an image and as XML. The

 directory is set in a file dialog. If the directory is not empty, you

 will be questioned if you risk to overwrite its contents.

 It is possible to export different maps into the same directory. Each

 file generated will have the map's name as prefix, e.g. {\tt todo.vym}

 becomes {\tt todo.xml}, {\tt todo.png}, {\tt todo-image-1.png} and so

 on. This is useful if e.g. for a website several combined maps have to

 be stored in the same directory.

 \subsection{Import} 

 At the moment \vym can read a directory structure. This is mainly for

 testing \vym e.g. to easily create huge maps used for benchmarks (yes,

 there is still room to optimize \vym ;-)

 Many other applications meanwhile can export their data using XML, so

 volunteers to write import filters are welcome.

 \subsection{File format}

 \vym maps usually have the postfix "{\tt .vym}" and represent a

 compressed archive of data. If you want to have a

 closer look into the data structure, just uncompress the map manually

 using

 \begin{verbatim}

 	unzip vymfile.vym

 \end{verbatim}

 A directory named {\tt vymfile} will be created containing further

 directories both for {\tt images} and {\tt flags}. In the {\tt vymfile}

 directory you will find the map itself, usually named {\tt vymfile.xml}.

 This file can be loaded directly into \vym, it does not have to be

 compressed. If you want to compress all the data yourself, use

 \begin{verbatim}

 	cd vymfile

 	zip -r vymfile.vym .

 \end{verbatim}

 %Where does vym save its settings? -> ~/.qt/vymrc

 \section{History of \vym}

 \subsection{Future}

 There are lots of features which might find their way into \vym.

 Together with \vym you should have received a directory with example

 maps e.g. on SUSE~LINUX this is

 \begin{center}

 	{\tt /usr/share/doc/packages/vym/demos}

 \end{center}

 where you find the map {\tt todo.vym}. It lists quite a lot of things to

 be done in future. If you have more ideas, contact the author at

 {\tt vym@insilmaril.de}.
