-/*
- * This command is fairly versatile and hence the usage might be a bit confusing.
- * The standard usage of this command is to add one or more certs to a Trust
- * Settings domain, along with optional usage constraints. Often, but not
- * necessarily, you'd also add the cert to a keychain while you're adding
- * it to Trust Settings.
- *
- * -- To add someRoot.cer to your login keychain and to your Trust Settings as
- * an unrestricted root cert:
- *
- * % security add-trusted-cert -k login.keychain someRoot.cer
- *
- * -- To add anotherRoot.cer to the local admin trust settings, only for policy
- * ssl, without adding it to a keychain (presumably because it's already in
- * a keychain somewhere else):
- *
- * % security add-trusted-cert -p ssl -d anotherRoot.cer
- *
- * The more obscure uses involve trust settings files.
- *
- * This command can also operate on trust settings as files instead of
- * modifying an actual on-disk Trust Settings record. One standard use for
- * this function is in the creation of the system Trust Settings, which
- * are immutable at runtime via the SecTrustSettings API. You provide a
- * file name for this option via -f settingsFile. If the file does not
- * exist, a new empty Trust Settings will be created, and certs and/or
- * a default will be added to that record, and the record will be written
- * out to the filename you provide (infile = outfile, always).
- *
- * -- To create Trust Settings record with one cert in it, restricted to
- * policy SSL:
- *
- * % security add-trusted-cert -p ssl -f someTrustSettingsFile.plist -r someRoot.cer
- *
- * You can also use the -f option and specify no certs, in which case an empty
- * Trust Settings record will be created. This can be useful if you want to
- * quickly reset the Trust Settings in a given domain to "empty"; the
- * empty Trust Settings record can be imported via the trust-settings-import
- * command.
- *
- * -- To reset the admin trust settings to "empty":
- *
- * % security add-trusted-cert -f emptySettingsFile.plist
- * % security trust-settings-import -d emptySettingsFile.plist
