/** @page KSpreadScripting KSpread Scripting Plugin
*
* The KSpread scripting plugin offers flexible access to the
* Kross scripting framework. Languages like Python or Ruby
* could be used to script KSpread, extend the functionality
* with script-packages, automate tasks or control the
* runtime-environment.
*
* \li The \a ScriptingPart class implements a KPart component
*     to integrate scripting into KSpread.
* \li The \a ScriptingModule class enables access to the KSpread
*     functionality from within the scripting backends.
* \li The \a ScriptingFunction class provides access to the KSpread::Function
*     functionality to deal with formula functions that are written in
*     a scripting language like Python or Ruby.
* \li The \a ScriptingCellListener class implements a listener to changes
      within cells of a sheet.
* \li The \a ScriptingReader class provides abstract high-level functionality
*     to read content from KSpread sheets.
* \li The \a ScriptingWriter class provides abstract high-level functionality
*     to write content to KSpread sheets and to manipulate the content of cells.
* \li The \a ScriptingSheetsListView provides provides a listview-widget that
*     displays all sheets and lets the user choose 0..n of them plus specify
*     cell-ranges for all of them.

* @section Examples
*
* Python example to write content of a sheet to stdout;
* @code
* #!/usr/bin/env kross
* # The OpenDocument Spreadsheet file that we like to read.
* filename = "/home/kde4/invoicetemplate.ods"
* # Import Kross and fetch the KSpread module.
* import Kross
* kspread = Kross.module("kspread")
* # Try to open the file.
* if not kspread.openUrl(filename):
*     raise "Failed to open the file \"%s\"." % filename
* # Get the sheet we like to print to stdout.
* sheet = kspread.sheetByName( kspread.sheetNames()[0] )
* # Iterate now through all cells on the sheet.
* for row in range(sheet.maxRow()):
*     # Put the content of the row into the record-list.
*     record = []
*     for col in range(sheet.maxColumn(), 0, -1):
*         value = sheet.text(col, row)
*         if value or len(record) > 0:
*             record.insert(0,value)
*     # If the record has at least one cell print it.
*     if len(record) > 0:
*         print record
* @endcode
*
* Python example to read template, set content and write new file;
* @code
* #!/usr/bin/env kross
* # The OpenDocument Spreadsheet file that we like to read from.
* templatefile = "/home/kde4/invoicetemplate.ods"
* # The OpenDocument Spreadsheet file that we like to write to.
* savefile = "/home/kde4/invoice.ods"
* # Import Kross and fetch the KSpread module.
* import Kross
* kspread = Kross.module("kspread")
* # Try to open the file.
* if not kspread.openUrl(templatefile):
*     raise "Failed to open the file \"%s\"." % templatefile
* # Get the sheet we like to manipulate.
* sheet = kspread.sheetByName( kspread.sheetNames()[0] )
* # Set the content of some cells.
* sheet.setText(0,7,"Joe User")
* sheet.setText(0,8,"Userstreet. 1")
* sheet.setText(0,9,"Testcasecity")
* # Finally write the new OpenDocument Spreadsheet file.
* if not kspread.saveUrl(savefile):
*     raise "Failed to save the file \"%s\"." % savefile
* @endcode
