* Release 1.5.

* (all): Updated copyright notices for 2010.

* FAQ, INSTALL, LICENSE, README: Reformatted as ReStructuredText.

* FAQ: Updated to mention alternative sources for NOAA's stations
list, in case the recommended one is unavailable (thanks Celejar!).

* NEWS: Renamed to ChangeLog and refactored into GNU format.

* weather: Added some comment padding between the shebang line and
the copyright, so that distributions wishing to carry patches which
modify the interpreter path don't have to refresh them every year
when the copyright line changes in their context.

* weather, weather.1, weatherrc.5, weather.py: Added experimental
alert, atypes, aurl and zones options to support retrieval,
filtering and formatting of unexpired NWS severe weather advisories.

* weather.1, weatherrc.5: Minor cosmetic fixes to option
descriptions.

* weather.1, weatherrc.5, weather.py: Added imperial and metric
options to filter/convert display units (thanks to Andrew Carter for
this suggestion!).

* weather.py: Fixed a METAR parsing error which would trigger an
IndexError exception if the NWS didn't have a station description on
file (thanks to Celejar for reporting the bug!). Fixed METAR title
line parsing to look for human-readable city and state in the first
line--previous code stopped showing the city name after NWS made
slight format mods. Upped the version to 1.5.

* weatherrc: Additional PIE (Saint Petersburg, FL), PNC (Ponca City,
OK), and PNS (Pensacola, FL) aliases.

-------------------------------------------------
The list of stations is found at http://weather.noaa.gov/data/nsd_cccc.gz (it's
thousands of lines long, so I recommend keyword searching in your browser or
using grep(1) to find what you're looking for). From time to time, the
compression on their site seems to be failing, resulting in zero-byte files. If
you run into this issue, you can get uncompressed and zip-compressed versions
by replacing the "gz" suffix in the URL with "txt" or "zip" respectively. The
list can also be obtained from the following URLs in a pinch, though they are
not guaranteed to be up to date (thanks Celejar!):

4. I live outside the USA--can this be made to work for me
anyway?
METAR station IDs can be found for cities and airports worldwide,
but forecast data is harder to come by. If you have any
recommendations of forecast data for other countries available in a
format like NOAA's, I will be happy to try and find a way to
integrate it into the weather utility, but I suspect that some
serious modification would be necessary given that the data is
likely to be published in a non-English language, requiring some
additional input from speakers of that language for how to handle
filtering and formatting of the text.

5. Why do I get the wrong forecast when specifying -i or --id? 5. Why do I get the wrong forecast when specifying -i or --id?
--------------------------------------------------------------
The -i or --id switch (or the id parameter in an alias definition), only tells
weather(1) what current conditions to retrieve. If you specify -f or --forecast
on the command line (or forecast=True in an alias) without providing a city
name and state abbreviation (-c/--city and -s/--st, or city and st in an alias)
and are seeing an actual forecast, then you probably have a default city and
state abbreviation set in your config. See question 3 above for information on
figuring out what city name and state abbreviation to use, and the manual for
weatherrc(5) for information on defining aliases.

WHAT? What?
-----
This command-line utility is intended to provide quick access to current
weather conditions and forecasts. Presently, it is capable of returning data
for localities throughout the USA by retrieving and formatting decoded METARs
(Meteorological Aerodrome Reports) from NOAA (the USA National Oceanic and
Atmospheric Administration) and forecasts from NWS (the USA National Weather
Service). The tool is written to function in the same spirit as other
command-line informational utilities like cal(1), calendar(1) and dict(1). It
can retrieve arbitrary weather data via specific command-line switches (station
ID, city, state), or aliases can be configured system wide and on a per-user
basis. It can be freely used and redistributed under the terms of a BSD-like
License.
