=head1 NAME

tv_grab_ar - Grab TV listings for Argentina.

=head1 SYNOPSIS

tv_grab_ar --help

tv_grab_ar [--config-file FILE] --configure [--gui OPTION]

tv_grab_ar [--config-file FILE] [--output FILE] [--days N]
           [--offset N] [--quiet] [--GetDetails]

tv_grab_ar --list-channels

tv_grab_ar --capabilities

tv_grab_ar --version

=head1 DESCRIPTION

Output TV listings for several channels available in Argentina.
Now supports the terrestrial analog tv listings, which is the most common tv 
viewed in Argentina. 
The tv listings comes from http://www.buscadorcablevision.com.ar/
The grabber relies on parsing HTML so it might stop working at any time.

First run B<tv_grab_ar --configure> to choose, which channels you want
to download. Then running B<tv_grab_ar> with no arguments will output
listings in XML format to standard output.

B<--configure> Prompt for which channels,
and write the configuration file.

B<--config-file FILE> Set the name of the configuration file, the
default is B<~/.xmltv/tv_grab_ar.conf>.  This is the file written by
B<--configure> and read when grabbing.

B<--gui OPTION> Use this option to enable a graphical interface to be used.
OPTION may be 'Tk', or left blank for the best available choice.
Additional allowed values of OPTION are 'Term' for normal terminal output
(default) and 'TermNoProgressBar' to disable the use of XMLTV::ProgressBar.

B<--output FILE> Write to FILE rather than standard output.

B<--days N> Grab N days.  The default is 3.

B<--offset N> Start N days in the future.  The default is to start
from today.

B<--quiet> Suppress the progress messages normally written to standard
error.

B<--capabilities> Show which capabilities the grabber supports. For more
information, see L<http://wiki.xmltv.org/index.php/XmltvCapabilities>

B<--version> Show the version of the grabber.

B<--help> Print a help message and exit.

=head1 BUGS

This grabber extracts all information from cablevision website. Any change in this
web page may cause this grabber to stop working.
Retrieving the description information adds a considerable amount of time to the run and makes the file quite large.
migth be a good idea to add a cache file the keeps the program description so there is no need to fetch it.

# Author's Updates
#   1.15   honir
#     *    Re-aply patch 1.12 which was inadvertently overwritten by 1.13
#   1.14   honir
#     *    Major modification to use new website structure
#   1.14 ?        Mariano Cosentino
#               *       added function to handle character conversion to utf-8
#   1.13        Mariano Cosentino
#               *       solved issue with descriptions
#   1.12        rmeden
#               apply Karl's patches to remove switch statements
#   1.10 	Mariano Cosentino
#		* 	fixed prototype warning
#		* 	Removed default value for location, as the old channel ids are no compatible with the site's new format.
#   1.9 	Mariano Cosentino
#		* 	The source website changed, I've adapted the script to the new format
#		*	Additional information is now handled directly here, no need for most of tv_extractinfo_ar
#		*	Added support for locations. 
#		*	*	Added parameter --zone for Zone ovewride w/o running full config
#		*	*	TELECENTRO is handled as a zone.
#		*	*	DirectTV is handled as a zone. *** in any case, if you have DTV, you should be using TV_GRAB_DTV_LA instead of this grabber :-) ***
#		*	*	All other Zones are extracted automatically from the CV website and all this zones have Cablevision's programming (not Telecentro, no DTV)
#		*	*	The "default" Zone is still Capital Federal / Gran Buenos Aires (Cablevision zone 3)
#		*	*	This is still to be tested by people outside GBA to see if is acurate. 
#		*	*	This is based on the work of Mauro Meloni and his Phyton version of TV_GRAB_AR http://mauromeloni.com.ar/files/tv_grab_ar.py.
#		*	Added parameter --getdetails to allow the user to control if they want the full details (time consuming) *** I should probably put it in the config section ***
#		* 	While it's working fine, this version still has a lot of room to improvements. I decided to release a quick-and-dirty version in order to have it up and running and then I wil work on the enhacements.
#		*	Some additional error handling should avoid fatal failures when the Cablevision  website becomes unresponsive (far too often for my taste).
#   1.8		rmeden
#		apply dekarl's patch 3057655 to update lots of xmltv.org links
#   1.7 	Mariano Cosentino
#		* 	The source website changed, I've adapted the script to the new format
#		*	Enhaced the handling of latin chars.
#		*	Added control and cache to avoid downloading the same program data multiple times in the same session.
#   1.6 	Mariano Cosentino
#		* 	Added descriptions support
#		*	All properties (director, autor, etc) are appended to the description for added value
#		*	All times are now UTC as per XMLTV recomendations
#		*	Cablevision and Multicanal use the same format (both are the same company now) so added variable to customize where to grab the listings from.



# Author's TODOs & thoughts
#
# Add channel logo support (download from $urlRoot/logos/lg_99.png where 99 is the channel id)
# Add Support for Argentinean DST
# add properties in the corresponding XMLTV fields without relying on the tv_extractinfo_ar (partialy done)
# migth be a good idea to add a cache file the keeps the program description so there is no need to fetch it.
