/**
 * This plugin requires a separate program called PhpWeather. For more
 * information and to download PhpWeather, see:
 *
 *   http://sourceforge.net/projects/phpweather/
 *
 * Usage:
 *
 * <?plugin PhpWeather ?>
 * <?plugin PhpWeather menu=true ?>
 * <?plugin PhpWeather icao=KJFK ?>
 * <?plugin PhpWeather language=en ?>
 * <?plugin PhpWeather units=only_metric ?>
 * <?plugin PhpWeather icao||=CYYZ cc||=CA language||=en menu=true ?>
 *
 * If you want a menu, and you also want to change the default station
 * or language, then you have to use the ||= form, or else the user
 * wont be able to change the station or language.
 *
 * The units argument should be one of only_metric, only_imperial,
 * both_metric, or both_imperial.

// Revision 1.10  2004/02/17 12:11:36  rurban
// added missing 4th basepage arg at plugin->run() to almost all plugins. This caused no harm so far, because it was silently dropped on normal usage. However on plugin internal ->run invocations it failed. (InterWikiSearch, IncludeSiteMap, ...)
