-The TRUSTARGS are three strings of zero or more alphabetic
-characters, separated by commas.  They define how the certificate should be trusted for SSL, email, and object signing, and are explained in the [certutil docs](http://www.mozilla.org/projects/security/pki/nss/tools/certutil.html#1034193) or [Meena's blog post on trust flags](https://blogs.oracle.com/meena/entry/notes_about_trust_flags).

-This should work now, because [NSS bug 531160](https://bugzilla.mozilla.org/show_bug.cgi?id=531160) is claimed to be fixed in a related bug report.  If it doesn't work, then to work around the NSS bug, you have to trust it as a CA using the "C,," trust flags.
