Usage: $w3_argv0 [options] [city[,state][;country]]
Description:
  Surfraw real time weather information (various sources)
Local options:
  -city=CITY|US_POSTCODE	Town or City or (US only) postcode
				Default: $SURFRAW_weather_city
				Environment: SURFRAW_weather_city
  -country=COUNTRY		Two letter domain-style country code
				Default: $SURFRAW_weather_country
				Environment: SURFRAW_weather_country
  -provider=yahoo		Weather provision service
				Default: $SURFRAW_weather_provider
                                Environment: SURFRAW_weather_provider
  -state=STATE			State, province or region
				Default: $SURFRAW_weather_state
				Environment: SURFRAW_weather_state
Examples:
  $w3_argv0 -country=au -state=vic -city=sydney
  $w3_argv0 -country=us -state=nm -city="white sands"
  $w3_argv0 london\\;uk
  $w3_argv0 melbourne
Bugs:
  The "yahoo" provider, while multi-country, does not understand
  states outside the context of the Uninted State of America.

  This elvi is named "wetandwild" instead of "weather" due to
  conflicts with a common tcl/expect script of the same name.
