301 =item $p->add ($name => [$value], [$name => $value,...])
302
303 Adds parameter name=value pair.
304
305 Example:
306 $p->add (title => 'foo of bar'); ## title="foo of bar"
307 $p->add (subject => 'hogehoge, foo'); ## subject*=''hogehoge%2C%20foo
308 $p->add (foo => ['bar', language => 'en']) ## foo*='en'bar
309 $p->add ('text/plain', ['', value => 1]) ## text/plain
310
311 This method returns array reference of (name, {value => value, attribute...}).
312
313 Available options: charset (charset name), language (language tag),
314 value (1/0, see example above).
