       METAR  reports  are meteorological weather reports for aviation. metar is a small program which downloads
       weather reports for user-specified stations and optionally decodes them into a human-readable format.

       Aviation weather stations are commonly referred to by ICAO designator.  The  ICAO  is  the  International
       Civil  Aviation  Organization,  a international standardization body for civil organization. For example,
       KJFK is the ICAO identifier for John F. Kennedy  Airport  in  New  York,  New  York,  EHAM  is  the  ICAO
       identifier for Amsterdam Schiphol Airport, The Netherlands, etc.

       If the environment variable METARURL is set, metar will attempt to download the weather report from  that
       location,  rather than from the default (the NOAA web site). The value of METARURL will be postfixed with
       the capitalized station ID, followed by the .TXT extension.

       For example, if you have METAR reports in your home directory, setting METARURL to $HOME and  asking  for
       the weather report of ehgr will result in the file $HOME/EHGR.TXT to be read.
