	// This is an export format file (which must reside within the 'export/' sub-directory of your refbase root directory). It contains a version of the
	// 'exportRecords()' function that outputs records according to the standard export format used e.g. by commercial bibliographic packages like 'Reference Manager' (http://www.refman.com).
	// This function is basically a wrapper for the bibutils 'xml2ris' command line tool (http://www.scripps.edu/~cdputnam/software/bibutils/bibutils.html).

	// --------------------------------------------------------------------

	// --- BEGIN EXPORT FORMAT ---

	// Export found records in 'RIS' format:

	// Requires the following packages (available under the GPL):
	//    - bibutils <http://www.scripps.edu/~cdputnam/software/bibutils/bibutils.html>
	//    - ActiveLink PHP XML Package <http://www.active-link.com/software/>

	function exportRecords($result, $rowOffset, $showRows, $exportStylesheet, $displayType)
	{
		// function 'exportBibutils()' is defined in 'execute.inc.php'
		$risSourceText = exportBibutils($result,"xml2ris");

		// NOTE: the 'exec()' command that is used in function 'execute()' in file 'execute.inc.php'
		//       does not include trailing whitespace in its '$output' array [*]; since this would
		//       chop off trailing whitespace from closing RIS 'ER  - ' tags, we add it back here
		//       [*] see <http://www.php.net/manual/en/function.exec.php>
		return preg_replace("/^ER  -$/m", "ER  - ", $risSourceText);
	}

	// --- END EXPORT FORMAT ---
