+By default @command{mimeview} asks for comnfirmation before running
+interpreter to view a message. If this option is used without
+argument, it disables the default behavior for all message
+types. Otherwise, if argument @var{type-list} is given, it specifies
+a comma-separated list of MIME types for which no questions should be
+asked. Elements of this list may include shell-style globbing
+patterns, e.g. setting

+@smallexample

+type @samp{image/jpeg}.
+
+  Notice, that when the long form is used, its argument
+must be separated from the option by a single equal sign, as shown
+in the example above. When the short form (@option{-a}) is used, its argument
+must follow the option immediately, without any intervening whitespace,
+e.g. @option{-a'text/*'}).

+This options tells @command{mimeview} that it should run in
+non-interactive mode. In this mode prompting is disabled, and
+the normal mailcap @code{command} field is not executed. Instead
+@command{mimeview} will execute the command specified in
+the @code{print} field. If there is nothing in the print field,
+the mailcap entry is ignored and the search continues for a matching
+mailcap entry that does have a @code{print} field.
