+/**
+ * Base class for terminal emulation back-ends.
+ *
+ * The back-end is responsible for decoding an incoming character stream and 
+ * producing an output image of characters.
+ *
+ * When input from the terminal is received, the receiveData() slot should be called with
+ * the data which has arrived.  The emulation will process the data and update the 
+ * screen image accordingly.  The codec used to decode the incoming character stream
+ * into the unicode characters used internally can be specified using setCodec() 
+ *
+ * The size of the screen image can be specified by calling setImageSize() with the 
+ * desired number of lines and columns.  When new lines are added, old content
+ * is moved into a history store, which can be set by calling setHistory(). 
+ *
+ * The screen image can be accessed by creating a ScreenWindow onto this emulation 
+ * by calling createWindow().  Screen windows provide access to a section of the 
+ * output.  Each screen window covers the same number of lines and columns as the 
+ * image size returned by imageSize().  The screen window can be moved up and down
+ * and provides transparent access to both the current on-screen image and the 
+ * previous output.  The screen windows emit an outputChanged signal
+ * when the section of the image they are looking at changes.
+ * Graphical views can then render the contents of a screen window, listening for notifications
+ * of output changes from the screen window which they are associated with and updating 
+ * accordingly. 
+ *
+ * The emulation also is also responsible for converting input from the connected views such
+ * as keypresses and mouse activity into a character string which can be sent
+ * to the terminal program.  Key presses can be processed by calling the sendKeyEvent() slot,
+ * while mouse events can be processed using the sendMouseEvent() slot.  When the character
+ * stream has been produced, the emulation will emit a sendData() signal with a pointer
+ * to the character buffer.  This data should be fed to the standard input of the terminal
+ * process.  The translation of key presses into an output character stream is performed
+ * using a lookup in a set of key bindings which map key sequences to output
+ * character sequences.  The name of the key bindings set used can be specified using
+ * setKeyBindings()
+ *
+ * The emulation maintains certain state information which changes depending on the 
+ * input received.  The emulation can be reset back to its starting state by calling 
+ * reset().  
+ *
+ * The emulation also maintains an activity state, which specifies whether
+ * terminal is currently active ( when data is received ), normal
+ * ( when the terminal is idle or receiving user input ) or trying
+ * to alert the user ( also known as a "Bell" event ).  The stateSet() signal
+ * is emitted whenever the activity state is set.  This can be used to determine
+ * how long the emulation has been active/idle for and also respond to
+ * a 'bell' event in different ways.

+   An arbitrary long scroll.
+
+   One can modify the scroll only by adding either cells
+   or newlines, but access it randomly.
+
+   The model is that of an arbitrary wide typewriter scroll
+   in that the scroll is a serie of lines and each line is
+   a serie of cells with no overwriting permitted.
+
+   The implementation provides arbitrary length and numbers
+   of cells and line/column indexed read access to the scroll
+   at constant costs.
+
+KDE4: Can we use QTemporaryFile here, instead of KTempFile?
+
+FIXME: some complain about the history buffer comsuming the
+       memory of their machines. This problem is critical
+       since the history does not behave gracefully in cases
+       where the memory is used up completely.
+
+       I put in a workaround that should handle it problem
+       now gracefully. I'm not satisfied with the solution.
+
+FIXME: Terminating the history is not properly indicated
+       in the menu. We should throw a signal.
+
+FIXME: There is noticeable decrease in speed, also. Perhaps,
+       there whole feature needs to be revisited therefore.
+       Disadvantage of a more elaborated, say block-oriented
+       scheme with wrap around would be it's complexity.

+/**
+    \brief An image of characters with associated attributes.
+
+    The terminal emulation ( Emulation ) receives a serial stream of
+    characters from the program currently running in the terminal.
+    From this stream it creates an image of characters which is ultimately
+    rendered by the display widget ( TerminalDisplay ).  Some types of emulation
+    may have more than one screen image. 
+
+    getImage() is used to retrieve the currently visible image
+    which is then used by the display widget to draw the output from the
+    terminal. 
+
+    The number of lines of output history which are kept in addition to the current
+    screen image depends on the history scroll being used to store the output.  
+    The scroll is specified using setScroll()
+    The output history can be retrieved using writeToStream()
+
+    The screen image has a selection associated with it, specified using 
+    setSelectionStart() and setSelectionEnd().  The selected text can be retrieved
+    using selectedText().  When getImage() is used to retrieve the the visible image,
+    characters which are part of the selection have their colours inverted.

+   `Screen' class or by the emulation class itself.
+
+   The pipeline proceeds as follows:
+
+   - Tokenizing the ESC codes (onReceiveChar)
+   - VT100 code page translation of plain characters (applyCharset)
+   - Interpretation of ESC codes (tau)
+
+   The escape codes and their meaning are described in the
+   technical reference of this program.

+
+// Tokens ------------------------------------------------------------------ --
+
+/*
+   Since the tokens are the central notion if this section, we've put them
+   in front. They provide the syntactical elements used to represent the
+   terminals operations as byte sequences.
+
+   They are encodes here into a single machine word, so that we can later
+   switch over them easily. Depending on the token itself, additional
+   argument variables are filled with parameter values.
+
+   The tokens are defined below:
+
+   - CHR        - Printable characters     (32..255 but DEL (=127))
+   - CTL        - Control characters       (0..31 but ESC (= 27), DEL)
+   - ESC        - Escape codes of the form <ESC><CHR but `[]()+*#'>
+   - ESC_DE     - Escape codes of the form <ESC><any of `()+*#%'> C
+   - CSI_PN     - Escape codes of the form <ESC>'['     {Pn} ';' {Pn} C
+   - CSI_PS     - Escape codes of the form <ESC>'['     {Pn} ';' ...  C
+   - CSI_PR     - Escape codes of the form <ESC>'[' '?' {Pn} ';' ...  C
+   - CSI_PE     - Escape codes of the form <ESC>'[' '!' {Pn} ';' ...  C
+   - VT52       - VT52 escape codes
+                  - <ESC><Chr>
+                  - <ESC>'Y'{Pc}{Pc}
+   - XTE_HA     - Xterm hacks              <ESC>`]' {Pn} `;' {Text} <BEL>
+                  note that this is handled differently
+
+   The last two forms allow list of arguments. Since the elements of
+   the lists are treated individually the same way, they are passed
+   as individual tokens to the interpretation. Further, because the
+   meaning of the parameters are names (althought represented as numbers),
+   they are includes within the token ('N').

+/**
+ * @obsolete Use KProcess and KPtyProcess instead.
+ *
+ * Child process invocation, monitoring and control.
+ * This class works only in the application's main thread.
+ *
+ * <b>General usage and features:</b>\n
+ *
+ * This class allows a KDE application to start child processes without having
+ * to worry about UN*X signal handling issues and zombie process reaping.
+ *
+ * @see K3ProcIO
+ *
+ * Basically, this class distinguishes three different ways of running
+ * child processes:
+ *
+ * @li  DontCare -- The child process is invoked and both the child
+ * process and the parent process continue concurrently.
+ *
+ * The process is started in an own session (see setsid(2)).
+ *
+ * @li  NotifyOnExit -- The child process is invoked and both the
+ * child and the parent process run concurrently.
+ *
+ * When the child process exits, the K3Process instance
+ * corresponding to it emits the Qt signal processExited().
+ * Since this signal is @em not emitted from within a UN*X
+ * signal handler, arbitrary function calls can be made.
+ *
+ * Be aware: When the K3Process object gets destructed, the child
+ * process will be killed if it is still running!
+ * This means in particular, that it usually makes no sense to use
+ * a K3Process on the stack with NotifyOnExit.
+ *
+ * @li  OwnGroup -- like NotifyOnExit, but the child process is started
+ * in an own process group (and an own session, FWIW). The behavior of
+ * kill() changes to killing the whole process group - this makes
+ * this mode useful for implementing primitive job management. It can be
+ * used to work around broken wrapper scripts that don't propagate signals
+ * to the "real" program. However, use this with care, as you disturb the
+ * shell's job management if your program is started from the command line.
+ *
+ * @li  Block -- The child process starts and the parent process
+ * is suspended until the child process exits. (@em Really not recommended
+ * for programs with a GUI.)
+ * In this mode the parent can read the child's output, but can't send it any
+ * input.
+ *
+ * K3Process also provides several functions for determining the exit status
+ * and the pid of the child process it represents.
+ *
+ * Furthermore it is possible to supply command-line arguments to the process
+ * in a clean fashion (no null-terminated stringlists and such...)
+ *
+ * A small usage example:
+ * \code
+ *   K3Process *proc = new K3Process;
+ *
+ *   *proc << "my_executable";
+ *   *proc << "These" << "are" << "the" << "command" << "line" << "args";
+ *   QApplication::connect(proc, SIGNAL(processExited(K3Process *)),
+ *                         pointer_to_my_object, SLOT(my_objects_slot(K3Process *)));
+ *   proc->start();
+ * \endcode
+ *
+ * This will start "my_executable" with the commandline arguments "These"...
+ *
+ * When the child process exits, the slot will be invoked.
+ *
+ * <b>Communication with the child process:</b>\n
+ *
+ * K3Process supports communication with the child process through
+ * stdin/stdout/stderr.
+ *
+ * The following functions are provided for getting data from the child
+ * process or sending data to the child's stdin (For more information,
+ * have a look at the documentation of each function):
+ *
+ * @li writeStdin()
+ *  -- Transmit data to the child process' stdin. When all data was sent, the
+ * signal wroteStdin() is emitted.
+ *
+ * @li When data arrives at stdout or stderr, the signal receivedStdout()
+ * resp. receivedStderr() is emitted.
+ *
+ * @li You can shut down individual communication channels with
+ * closeStdin(), closeStdout(), and closeStderr(), resp.
+ *

+# This configuration table allows to customize the
+# meaning of the keys.
+#
+# The syntax is that each entry has the form : 
+#
+#   "key" Keyname { ("+"|"-") Modename } ":" (String|Operation)
+#
+# Keynames are those defined in <qnamespace.h> with the
+# "Qt::Key_" removed. (We'd better insert the list here)
+#
+# Mode names are : 
+#
+# - Shift
+# - Alt
+# - Control
+#
+#   The VT100 emulation has two modes that can affect the
+#   sequences emitted by certain keys. These modes are
+#   under control of the client program.
+#   
+# - Newline     : effects Return and Enter key.
+# - Application : effects Up and Down key.
+#
+# - Ansi        : effects Up and Down key (This is for VT52, really).
+#
+# Operations are
+#
+# - scrollUpLine
+# - scrollUpPage
+# - scrollDownLine
+# - scrollDownPage
+#
+# - emitSelection
+#
+# If the key is not found here, the text of the
+# key event as provided by QT is emitted, possibly
+# preceeded by ESC if the Alt key is pressed.
