+		<title>Placing components</title>
+		<para>On the left, you'll find the Components tab.</para>
+		
+		<para>Dragging a component from the sidebar into the circuit will place it under the mouse cursor. Alternatively, you can double click on an item in the Components sidebar to repeatedly add it to the circuit. In this mode, a copy of the selected component will be placed repeatedly on mouse left-clicking until either Escape is pressed, or the mouse is right-clicked.</para>
+		
+		<para>To reposition a component, left-click and drag. You'll find it snapping to the underlying grid. If you drag the component out of the right or bottom edges of the workarea, the workarea will resize itself to accomodate.</para>
+		
+		<para>All components have a notion of orientation; 0, 90, 180 and 270 degrees. Those that aren't symmetrical about an axis can also be flipped. To rotate a selection of components, either right click and select from the Orientation menu, or click on the rotate buttons in the toolbar. The latter can also be accessed by pressing the "[" and "]" keys (familiar to Inkscape users). The Item sidebar (on the right) provides a powerful method of setting the orientation by providing previews of the components. Flipping components is also only possibly via the Item sidebar.</para>
+	</sect1>
+	
+	<sect1 id="connecting_components">
+		<title>Connecting Components</title>
+		<para>There are two modes for creating connections (wires): automatic, and manual. These modes are selected via the "Connection Routing Mode" pulldown menu in the toolbar. Experiment with both - automatic routing is often better for small circuits, whereas more complex circuits may need manual routing.</para>
+		
+		<para>In automatic mode, create a connection by dragging from either a component pin or an existing connection, and releasing the mouse over the desired pin or connection. You'll see the straight-line being drawn turn orange when a valid connection will be created on mouse release. If the line you're drawing is black, it's either because there's nothing beneath the mouse cursor, or you're attempting to connect together two items which are already connected. When flowcharting, the criteria for a valid connection are more complex - but we'll get to that later.</para>
+		
+		<para>The best way to get a feel for manual connection routing is by experimenting with it. Click on the starting pin or connection, and then extend the proto-connector by moving the mouse away from where you clicked. To place a corner, left-click. To cancel drawing the connection, either press escape, or right-click the mouse.</para>
+		
+		<para>&kappname; tries its best to maintain the routes your connections take. However, if dragging a component results in the end points of a connection moving relative to each other, &kappname; will be forced to redraw the connection using auto-routing. Before moving a component, you can see which connectors will have to be rerouted - as they will turn grey on clicking.</para>
+		
+		<para>To remove an existing connection, select it by drawing a small select-rectangle over part of the connector, and hit delete.</para>
+	</sect1>
+	
+	<sect1 id="component_attributes">
+		<title>Component Attributes</title>
+		<para>Most components will have editable attributes, such as the resistance for resistors. By default, you can edit simple attributes in the toolbar, when a group of the same type of components are selected. If your selection contains a mixture of different types of components (such as resistors and capacitors), then no attributes will be displayed for editing.</para>
+		
+		<para>Some components have more advanced attributes which are not accesible via the toolbar. These are found in the Item sidebar on the right. The diode, for example, has a variety of behavioural characteristics that you can edit here.</para>
+		
+		<para>If your selection of components have different values for their attributes (for example, different resistances for a selection of resistors), the Item sidebar will have the disagreeing attributes greyed-out. You can enable these by clicking the "Merge properties" button.</para>
+		
+		<para>The "Defaults" button will reset the component attributes to the ones it had on creation.</para>
+		
+		<para>There is one type of attribute that cannot be editable by either the toolbar or Item sidebar - multiline text. Double clicking on the item will bring up a dialog box where the text can be entered.</para>
+	</sect1>
+	
+	<sect1 id="circuit_simulation">
+		<title>Simulation</title>
+		<para>By default, the simulation will be running when you create a new circuit. The status of the simulation is displayed in the lower right of a circuit view, and can be changed via the Tools menu. Firstly - a little explanation on how the Simulator works. This should allow you to make the most out of it.</para>
+		
+		<para>When a circuit is created or modified, the affected areas are partitioned up into groups of pins and connections that can be considered independent. Each group is then simulated as a seperate entity (although still interacting via the components), with the simulation provided dependent on the group's complexity. Complex groups, such as those involving nonlinear components like LEDs, are slow to simulate. Groups that contain only logic pins, of which only one controls the value on those pins, are the fastest to simulate.</para>
+		
+		<para>The results of the simulation are provided through several graphical means.</para>
+		
+		<para>The pins on the components will display voltage sidebars. These are coloured orange for positive voltage, and blue for negative voltage. Their length depends on the voltage level, and their width on the amount of current flowing through the pin. These can be turned off in the Work Area tab of the Configuration dialog.</para>
+		
+		<para>Hovering the mouse over a pin or connection will display a small tooltip showing the voltage and current at that point in the circuit. Several components also provide graphical feedback - for example, LEDs and voltmeters or ammeters.</para>
+		
+		<para>Lastly, there is the oscilloscope, discussed in the next section.</para>
+	</sect1>
+	
+	<sect1 id="oscilloscope">
+		<title>Oscilloscope</title>
+		<para>The oscilloscope can record logic, voltage and current data. The logic probe is optimized for storing boolean samples, and so should be used instead of the voltage probe when measuring logic.</para>
+		
+		<para>To collect data, create a new probe component, and attach it to an appropriate point in the circuit. You'll see the output immediately drawn in the oscilloscope. Adding more probes will squash the outputs next to each other - you can reposition these by dragging the arrows on the left of the oscilloscope view, and change their colours via the probe's attributes.</para>
+		
+		<para>For voltage and current probes, the range of input values can be adjusted in the "Item Editor" sidebar on the right.</para>
+		
+		<para>Zooming is controlled by a slider. The scaling is logarithmic; for every few pixels that the slider moves along, the zoom factor will be multipled by a constant. &kappname; simulates logic to a maximum precision of 1 microsecond, and at maximum zoom level, one microsecond is represented by 8 pixels.</para>
+		
+		<para>When the scrollbar is dragged to the end, it will remain there as new data is recorded. Otherwise, the position of the scrollbar remains fixed in time. The oscilloscope view can also be moved forwards and backwards by left-clicking and dragging the view. Due to limitations of the underlying widget system, scrolling will be very granular at maximum zoom.</para>
+		
+		<para>Right-clicking on the oscilloscope view brings up a menu where you can control the number of times the oscilloscope view is updated. This allows for either a smoother display, or reducing CPU usage.</para>
+	</sect1>
+	
+	<sect1 id="subcircuits">
+		<title>Subcircuits</title>
+		<para>Subcircuits offer a reusable and tidy way of using a circuit, when you're only interested in interacting with external connections to the circuit. The subcircuit is creating as an IC, with the pins acting as the interaction with the internal circuit.</para>
+		
+		<para>First, the circuit to be used in as a template for creating a subcircuit from must be constructed. The points of interaction are defined via "External Connection" components. These must be connected up, and positioned where you want the pin to be positioned on the subcircuit IC.</para>
+		
+		<para>Next, select the group of components and external connections to be turned into a subcircuit, and select "Create Subcircuit" from the right-click menu. You'll be offered to enter a name for the subcircuit. Once created, the name will popup in the Component selector under the Subcircuits selection. This can be treated as any normal component - with the additional option of removing it by right-clicking on the item and selecting Remove.</para>

+		<para>Debugging support is provided for Assembly, SDCC and Microbe, when they are open as a text document. From here, stepping is controlled via the Debug menu. There are two methods of starting the debugger.</para>
+		
+		<para>If the PIC program is already running in a circuit, then double-clicking on the PIC component will open up the program. For assembly PIC programs, the debugger for that text document will be linked into the PIC component. In this case, the debug menu cannot stop the PIC program - as this is owned by the PIC component.</para>
+		
+		<para>If the assembly file is already opened, then the debugger can be run via the Debug menu. After compiling the program, the debugger will be ready, with the PIC program paused at the first instruction. Note that when debugging high level languages, the current execution point will not be shown if there is no line that corresponds to the first assembly instruction to be executed. In this case, clicking next will bring the execution point to the first line in the program.</para>
+	</sect1>

+	<sect1 id="controlling_debugger">
+		<title>Controlling the Debugger</title>
+		
+		<para>The debugger can be in one of two modes: running, and stepping. While running, the PIC program will be simulated in realtime. To allow stepping, the PIC program must be paused - either by clicking on Interrupt in the Debug menu, or clicking on the pause button on the PIC component.</para>
+		
+		<para>In stepping mode, a green arrow in the margin of the text document indicates the next line to be executed (familiar to KDevelop users). It may be useful to turn on the icon border via the View menu (it can be permanently turned on via the Editor Settings dialog).</para>
+		
+		<para>There are three types of stepping:</para>
+		
+		<itemizedlist>
+			<listitem><para>Step into - This executes the current instruction. The green arrow is moved onto the next line to be executed.</para></listitem>
+			<listitem><para>Step over - If the next instruction to be executed is a call, or similar, then this will "step over" the call, returning to stepping mode once the call has returned. Otherwise, stepping over an instruction behaves identically to step. To put it technically - the initial stack level is recorded, and the program execution is paused once the stack level returns to its initial level.</para></listitem>
+			<listitem><para>Step out - If the current execution is inside a call, or similar, then this will wait until the call returns. Similarly to stepping over, this is equivalent to waiting until the stack level returns to one less than the initial level, if the initial level is greater than zero.</para></listitem>
+		</itemizedlist>
+		
+		<para>Breakpoints allow the execution to be paused when the PIC program reaches a given instruction. To toggle a breakpoint on the line containing the cursor, either use the Debug menu, or click on the icon border of the text document.</para>
+		
+		<para>The "Symbol Viewer" sidebar on the right shows the values of the Special Function Registers. To find out the value of a variable in the General Purpose Registers, you can hover your mouse over the variable name in an instruction that operates on that register. Note that the radix selection in the Symbol Viewer also controls how the value is displayed when hovering over a variable.</para>

+		<question>
+			<para>Configure can't find gpsim</para>
+		</question>
+		
+		<answer>
+			<para>Configure will attempt to compile several files to test for gpsim presence; testing for versions 0.21.4, 0.21.11 and 0.21.12. These files uses part of the gpsim API, that is also used by &kappname;, and was introduced in the respective gpsim versions. If it fails in compiling this program, it will display the warning to the user, and PIC simulation support will not be compiled into &kappname;. There are a number of possibly reasons for finding gpsim to fail:</para>
+			
+			<itemizedlist>
+				<listitem><para>gpsim >= 0.21.4 is not installed. &kappname; does not support gpsim-0.21.2 or gpsim-0.20.14 (or any earlier versions). Later versions may work; but this cannot be tested before they are released. The latest gpsim can be obtained from the <ulink url="http://www.dattalo.com/gnupic/gpsim.html">gpsim website</ulink>.</para></listitem>
+				<listitem><para>Gpsim is installed, but the header files could not be found. If gpsim is installed in a non-standard location, you may need to specify the location of the header files with "./configure --with-extra-includes=DIR". It is also likely you'll need to specify a library location with the configure option "--with-extra-lib" if the includes are in a non-standard location.</para></listitem>
+				<listitem><para>Gpsim is installed and the headers are somewhere where configure can find them, but there is some other glib craziness occuring.</para></listitem>
+			</itemizedlist>
+				
+			<para>Configure generates the file <computeroutput>config.log</computeroutput> which will contain details of exactly what went wrong. Searching for gpsim in this log should help you decide what's happened. As an example, here is part of the config.log file where one of the gpsim header files is missing:</para>
+			
+			<example><title>Possible config.log output where gpsim detection failed</title>

+		<question>
+			<para>&kappname; crashes when running a PIC program</para>
+		</question>
+		
+		<answer>
+			<para>Version 0.21.11 of gpsim contains a bug that may cause &kappname; to crash on the second running of a PIC program. This bug has since been fixed in gpsim-cvs. The &kappname; website provides a <ulink url="http://ktechlab.org/download/gpsim.php">patched version</ulink> of the stable release of gpsim that fixes this bug.</para>

+		<question>
+			<para>High Level Language (HLL) debugging does not work</para>
+		</question>
+		
+		<answer>
+			<para>Version 0.21.11 of gpsim contains a bug preventing HLL debugging from working. This bug has since been fixed in gpsim-cvs. The &kappname; website provides a <ulink url="http://ktechlab.org/download/gpsim.php">patched version</ulink> of the stable release of gpsim that fixes this bug.</para>

+	</qandaentry>
+	
+	<qandaentry>
+		<question>
+			<para>&kappname; uses lots of CPU</para>
+		</question>
+		
+		<answer>
+			<para>There are several possible causes. Simulation of circuits that contain both reactive and nonlinear components (such as capacitors and transistors) take a lot of CPU time to simulate. You can pause and resume the simulation via the Tools menu.</para>
+			
+			<para>Drawing of the work area (in particular, redrawing lots of rapidly updating voltage bars on pins) is also CPU intensive. You can reduce the refresh rate or turn off the voltage bars via the Settings dialog. The refresh rate of the Oscilloscope can also be reduced by right clicking on its display.</para>
+
+			<para>Note that the next major release of &kappname; will be a lot faster in both displaying the work area and simulating reactive and nonlinear components.</para>

+		
+		<para>It has been designed to be as easy to use and unintrusive as possible; all components and FlowParts have context sensitive help, and simulating electronics is as simple as dragging components onto the work area and creating connectors that autoroute themselves between their pins. &flowcode; allows users new to PICs to instantly create their own programs, while the electronic simulation allows stepping through a PIC's assembly program inside a circuit.</para>
