// Any entries whose key value ('foo' in $servers['foo']) begin with
// '_' (an underscore character) will be treated as prompts, and you
// won't be able to log in to them. The only property these entries
// need is 'name'. This lets you put labels in the list, like this
// example:
$servers['_prompt'] = array(
    'name' => 'Choose a mail server:'
);
