		os.system( 'python metrites.py > htmltemp' )
		f = open( htmltemp )
		htmldata = f.read()	

gives:

f undefined, builtin open = <built-in function open>, temp = '/home/nikos/www/data/private/htmltemp'
<type 'exceptions.IOError'>: [Errno 2] ��� ������� ������ ������ � ���������: '/home/nikos/www/data/private/htmltemp'
