* 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.

1. Can I help?
-
-Sure! Bug reports and feature suggestions are always welcome, but
-fixes and patches are of course preferred. Contact
-fungi@yuggoth.org if desired, but please read this FAQ and the
-included manuals for weather(1) and weatherrc(5) before asking
-questions that might be answered therein. One big way anyone can
-help is to provide me with some additional mappings of METAR
-station ID, city name and state abbreviation for inclusion in the
-default /etc/weatherrc file.

2. How do I figure out my local METAR station ID?
-
-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).
-
+-------------------------------------------------
+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!):
+
+ * http://www.rap.ucar.edu/weather/surface/stations.txt
+ * http://aviationweather.gov/adds/metars/stations.txt
3. How do I figure out my local city name and state abbreviation?
-
+-----------------------------------------------------------------
The forecasts can be located starting from
-http://weather.noaa.gov/pub/data/forecasts/city/ (choose the
-state abbreviation to get to a list of cities in that state).
-
-
-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?
-
-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.

+
+6. Where can I get a list of the NWS advisory zones for alerts?
+---------------------------------------------------------------
+The lists of advisory zones by region are found aggregated at
+http://weather.noaa.gov/pub/data/zonecatalog.curr.tar (it's several thousand
+files totalling well over a hundred thousand lines of text, so I recommend
+downloading, unpacking and using a recursive grep(1) to find what you're
+looking for).

-PREREQUISITES
+Prerequisites
+-------------
+You need the Python interpreter installed somewhere in your path (most modern
+UNIX derivatives come with one already). If you need to get Python, it can be
+obtained from http://www.python.org/ (but chances are your operating system at
+least provides some sort of native package for it, which you should probably
+install in whatever means is recommended by your OS vendor/distributor).

-An easy way to try it out is to unpack the tarball and change to the

+Running in Place
+----------------
+An easy way to try it out is to unpack the tarball and change to the resulting
+directory::
tar xzf weather-*.tar.gz
- cd weather
+ cd weather-*
./weather --version
./weather --help
man ./weather.1
./weather --forecast --no-conditions --city=charlotte --st=nc
./weather ord sea
-...and so on. The weather utility, included Python module and
-documentation are all fully functional when kept together in one
-directory, if somewhat inconvenient.

-
-INSTALLING THE UTILITY
+...and so on. The weather utility, included Python module and documentation are
+all fully functional when kept together in one directory, if somewhat
+inconvenient.
-The file named weather should be made executable and put somewhere
-in your path (/usr/local/bin/ or ~/bin/ for example). Similarly,
-weather.py needs to be somewhere in Python's include path. You can
-see your Python interpreter's default include path by running:

-
-CONFIGURATION
-
-The weatherrc file should go in /etc/ or you can save it in your

-alias configuration and overrides of the global /etc/weatherrc file.
-
-
-MANUALS
-
-Optionally, the weather.1 and weatherrc.5 files can be placed in
-sane locations for TROFF/NROFF manual files on your system (for
-example, /usr/local/share/man/ or ~/man/).

-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.
-
-
-WHY?
-
-My girlfriend had a long commute to/from work and school, and
-often wanted to check the weather both for home and her office.
-Unfortunately, starting a Web browser, pulling up a weather site,
-entering multiple ZIP codes and waiting for them to load is
-time-consuming for the marginally-impatient. Since she tended to
-stay logged into a shell server most of the time, I figured I'd
-install a quick command-line tool to retrieve weather info for
-her commute, but to my surprise, a quick search turned up little
-that met my basic requirements:
-
- * retrieve current data on-demand
- * provide both current conditions and short-term forecasts
- * simple, human-readable output
- * easy to configure and use
- * flexible command-line switches and options
-
-
-WHERE?
-
-A tarball for the most recent version of the weather utility can
-be had here:
-
- http://fungi.yuggoth.org/weather/src/
-
-Alternatively, Debian users can install the weather-util package
