-// This test verifies the SecureSocket functions addCertificate,
-// importCertificatesWithPrivateKeys, changeTrust, getCertificate, and
-// removeCertificate.
-
-// It loads a copy of the test certificate database,
-// removes all certificates and keys, then imports the certificates and keys
-// again.  Then it runs a secure server, using the user certificate (a
-// certificate with private key), and starts client processes that use
-// addCertificate to trust the certificate that signed the server's certificate.
-// The clients then test that they can successfully connect to the server.
