  ##  Plugin for htmlArea, to run code through the server's HTML Tidy
 ##   By Adam Wright, for The University of Western Australia
##    This is the server-side script, which dirty code is run through.

##  Distributed under the same terms as HTMLArea itself.

	// Either way, get some source code into $source

		fclose($pipes[0]);

		// Clean up after ourselves
		proc_close($process);
