#  This is a minimal sample script showing how the individual data
#  are accessed from the decoded report.  To produce the standard text 
#  summary of a report, use the string() method of the Metar object.
#  The parsed data are stored as attributes of a Metar object.
#  Individual attributes are either strings. instances of one of the
#  metar.Datatypes classes, or lists of tuples of these scalars.
#  Here's a summary, adapted from the comments in the Metar.Metar.__init__()
#    Attribute       Comments [data type]

#  The metar.Datatypes classes (temperature, pressure, precipitation,
#  speed, direction) describe an observation and its units.  They provide
#  value() and string() methods to that return numerical and string
#  representations of the data in any of a number of supported units.  
#  (You're going to have to study the source code for more details,
#  like the available methods and supported unit conversions for the
#  metar.Datatypes objects, etc..)  
#  In particular, look at the Metar.string()
#  method, and the functions it calls.
