/** Misc/acceptDrops
*
* SYNOPSIS
*   long acceptDrops(widget)
* DESCRIPTION
*   Calling this enables your widget to receive Drop events. In other words,
*   the user will be able to drag icons from her desktop and drop them on
*   your widget. The "itemDropped" callback is called as a result with the
*   data about the icon that was dropped on your widget. This allows, for
*   example, icon bars where items are added to the icon bar by Drag and
*   Drop.
* ARGUMENTS
*   * long widget -- karamba
* RETURN VALUE
*   1 if successful
*/
PyObject* py_accept_drops(PyObject *self, PyObject *args);

/** Misc/execute
*
* SYNOPSIS
*   long execute(command)
* DESCRIPTION
*   This command simply executes a program or command on the system. This is
*   just for convience (IE you could accomplish this directly through python,
*   but sometimes threading problems crop up that way). The only option is a
*   string containing the command to execute.
* ARGUMENTS
*   * string command -- command to execute
* RETURN VALUE
*   1 if successful
*/
PyObject* py_execute_command(PyObject* self, PyObject* args);

/** Misc/executeInteractive
*
* SYNOPSIS
*   long executeInteractive(widget, command)
* DESCRIPTION
*   This command executes a program or command on the system. But it allows
*   you to get any text that the program outputs. Futhermore, it won't freeze
*   up your widget while the command executes.
*
*   To use it, call executeInteractive with the reference to your widget and
*   an array of command options. The array is simply a list that contains the
*   command as the first entry, and each option as a seperate list entry.
*   Make sure to catch the returning value from executeInteractive(); it will
*   be the identifier (process number) for the command.
*
*   Output from the command triggers commandOutput callback. Among other items
*   commandOutput gives the process number of the command that gave the output.
*   This allows you to identify the output when running more than one command
*   at a time.
*
*   Example: 
*   To run the command "ls -la *.zip"
*
*      myCommand = ["ls", "-la", "*.zip"]
*      procID = karamba.executeInteractive(widget, myCommand)
*
*   To catch the output, screen commandOutput output for procID.
*
* ARGUMENTS
*   * long widget -- karamba
*   * list command -- command to execute
* RETURN VALUE
*   identification number of the executed command process
*/

/** Misc/run
*
*  SYNOPSIS
*    long run(name, command, icon, list_of_args)
*  DESCRIPTION
*    This command simply executes a program or command on the system.
*    The difference between run and execute is that run takes arguments,
*    and the name of the icon to be displayed.
*  ARGUMENTS
*    * string name -- name to be displayed
*    * string command -- command to execute
*    * string icon -- name of icon to be displayed
*    * string list_of_args -- arguments to be passed to the command
*  RETURN VALUE

/** Misc/attachClickArea
* 
*   SYNOPSIS
*     long attachClickArea(widget, meter, lB, mB, rB)
*   DESCRIPTION
*     It is possible to attach a clickarea to a meter (image or text field),
*     which is moved and resized correctly if the meter is moved or resized.
*
*     There is also a callback meterClicked(widget, meter, button) which is
*     called whenever a meter is clicked (if something is attached to it).
*     Given an Image or a TextLabel, this call makes it clickable. When a mouse
*     click is detected, the callback meterClicked is called.
*
*     lB, mB, and rB are strings that specify what command is executed when
*     this meter is clicked with the left mouse button, middle mouse button,
*     and right mouse button respectively. If given, the appropriate command is
*     executed when the mouse click is received.
*
*     The keyword arguments are all optional. If command is an empty string
*     nothing is executed.
*
*     For now the command given to RightButton has obviosly no effect (because
*     that brings up the SuperKaramba menu).
*
*   ARGUMENTS
*     * long widget -- karamba
*     * long meter -- pointer to meter
*     * string lB -- command to left mouse button
*     * string mB -- command to middle mouse button
*     * string rB -- command to right mouse button

*    Opens a new theme, giving it a pretty (alternative and by your

*
*  SYNOPSIS
*    long setIncomingData(widget, theme, info)
*  DESCRIPTION
*  Contacts a theme - identified by the pretty name - and stores a string
*  to be associated with the remote theme.  The difference between

*  by setIncomingData that the data has arrived.  Previous information,
*  if any, is overwritten.  Use getIncomingData to retrieve the last
*  stored information.
*  setIncomingData is not very sophisticated, and could benefit from
*  having info passed to it put into a queue, instead of being overwritten.

*
*  SYNOPSIS
*    long getIncomingData(widget)
*  DESCRIPTION

*    if you want to receive MouseUpdate button notifications.
*  ARGUMENTS
*    * long widget -- karamba
*    * long want_receive_right_button -- whether the widget will receive right clicks
*  RETURN VALUE
*    1 if successful

/** Misc/setWantMeterWheelEvent
*
*  SYNOPSIS
*    long setWantMeterWheelEvent(widget, want_receive_wheel_event)
*  DESCRIPTION
*    Enabling this allows themes to receive a wheel event when
*    the wheel is turned over a meter.
*    This function is available after version 0.42.
*    This behaviour is default in SuperKaramba 0.50 and later,
*    so this function will be not available after the 0.50 version.
*  ARGUMENTS
*    * long widget -- karamba
*    * long want_receive_wheel_event -- whether the theme will receive mouse wheel events
*  RETURN VALUE
*    1 if successful

*
*  SYNOPSIS
*    long managementPopup(widget)
*  DESCRIPTION
*    There's a management menu for SuperKaramba themes which
*    allows themes to be loaded, closed, moved to other
*    screens.  If you want this popup menu to appear, call
