    sys.stdout.write(inline)
    sys.stdout.write('\r\n')
    sys.stdout.flush()           
 
contentheader = 'Content-Type: text/html'
 
thepage = '''<html><head>
<title>%s</title>
</head><body>
%s
</body></html>
'''
h1 = '<h1>%s</h1>'
 
if __name__ == '__main__':
    cgiprint(contentheader)   #  
    cgiprint()                #
