 """This is a simple HTTP/FTP/SYNC/TCP/UDP/ server used for testing Chrome.
 
 It supports several test URLs, as specified by the handlers in TestPageHandler.
 By default, it listens on an ephemeral port and sends the port number back to
 the originating process over a pipe. The originating process can specify an
 explicit port if necessary.
 It can use https if you specify the flag --https=CERT where CERT is the path
 to a pem file containing the certificate and private key that should be used.
