/**
 * The <code>-cacert</code> keytol command handler is used to import a CA
 * trusted X.509 certificate into a key store.
 * <p>
 * Possible options for this command are:
 * <p>
 * <dl>
 *      <dt>-file FILE_NAME</dt>
 *      <dd>The fully qualified path of the file containing the trusted CA
 *      certificate to import. If omitted, the tool will process STDIN.
 *      <p></dd>
 *
 *      <dt>-storetype STORE_TYPE</dt>
 *      <dd>Use this option to specify the type of the key store to use. The
 *      default value, if this option is omitted, is that of the property
 *      <code>keystore.type</code> in the security properties file, which is
 *      obtained by invoking the {@link java.security.KeyStore#getDefaultType()}
 *      static method.
 *      <p></dd>
 *
 *      <dt>-keystore URL</dt>
 *      <dd>Use this option to specify the location of the key store to use.
 *      The default value is a file {@link java.net.URL} referencing the file
 *      named <code>.keystore</code> located in the path returned by the call to
 *      {@link java.lang.System#getProperty(String)} using <code>user.home</code>
 *      as argument.
 *      <p>
 *      If a URL was specified, but was found to be malformed --e.g. missing
 *      protocol element-- the tool will attempt to use the URL value as a file-
 *      name (with absolute or relative path-name) of a key store --as if the
 *      protocol was <code>file:</code>.
 *      <p></dd>
 *
 *      <dt>-storepass PASSWORD</dt>
 *      <dd>Use this option to specify the password protecting the key store. If
 *      this option is omitted from the command line, you will be prompted to
 *      provide a password.
 *      <p></dd>
 *
 *      <dt>-provider PROVIDER_CLASS_NAME</dt>
 *      <dd>A fully qualified class name of a Security Provider to add to the
 *      current list of Security Providers already installed in the JVM in-use.
 *      If a provider class is specified with this option, and was successfully
 *      added to the runtime --i.e. it was not already installed-- then the tool
 *      will attempt to removed this Security Provider before exiting.
 *      <p></dd>
 *
 *      <dt>-v</dt>
 *      <dd>Use this option to enable more verbose output.</dd>
 * </dl>
