=head1 DESCRIPTION

Output TV listings for several channels available in France (Hertzian,
Cable/satellite, Canal+ Sat).  The data comes from
guidetv-iphone.telerama.fr.  The default is to grab as many days as possible
from the current day onwards. The program description are
downloaded.

B<--configure-more-channels> Use this option to create AUTRES CHAINES list.
 This allow to grab listings for some channels that are not in automatically
generated lists.

B<--configure> Grab channels informations from the website and ask for
channel type and names.

B<--config-file FILE> Use FILE as config file instead of the default config
file. This allow to have different config files for i.e. different apps.

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 Term::ProgressBar.

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

B<--days N> Grab N days starting from today, rather than as many as
possible. Due to the website organization, the speed depends on
the --days value Default value is 11.

B<--offset N> Start grabbing N days from today, rather than starting
today.  N may be negative. Due to the website organization, N cannot
be inferior to -1.Default value is 0

B<--ch_prefix S> (string): string to add at the begining of XMLTV channel id
Default value is "C"

B<--ch_postfix S> (string): string to add at the end of XMLTV channel id
Default value is ".telerama.fr"

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

B<--perdays> Actually do nothing since "per days" is already set as default
grabbing mode. This option is kept in the event of "per weeks" set back as
default. In this case, it could be use to activate the "per days" grabbing mode.

B<--perweeks> Actually do nothing since "per days" is already forced as default

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

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

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

B<--delay> (integer). régle le delais maximum en 2 requete au serveur. Defaut 2

B<--no_cryptedcplus> Cache les programme crypté de Canal+.

B<--no_cryptedpprem> Cache les programme crypté de Paris Première.

=head1 CHANGELOG

1.8 Suppression de l'option --slow ne servait plus
         Ajout des option --ch_prefix et --ch_postfix pour définir le prefix et le suffixe
         du channel id. Par defaut "C" et ".telerama.fr" (conforme à l'existant)
         Correction de la description du programme dans l'entête
         Augmentation du nombre de jours récupérés par défaut (11)
         Ajout de la licence d'utilisation (GPL v3+ comme xmltv)
         Correction définitive (je pense) des problèmes d'encodage UTF8 (le xml généré passe xmltv:tv_validate_file)
         Diminution du délai entre 2 captures de page (malgré les dizaine d'essais que j'ai effectués,
         ça n'a pas posé de problème)
         Correction de l'entête du fichier xml généré qui indiquait toujours telepoche.
         Suppression du code mort (routines gérant le site de telepoche)
         Suppression de la routine tidy (puisque les problème d'encodage sont résolus smile )
         Correction de la récupération de l'image du programme (URL incorrecte), maintenant on peut afficher la petite photo
         Les informations suivantes sont maintenant récupérées :
        - Durée (corrigée)
        - Présence de sous-titrage (onscreen ou teletexte)
        - Scénariste(s)
        - Présentateur(s)
        - Invité(s)
        - Compositeur(s), il faut une version de xmltv >= 5.58
        - stereo/dolby/dolby digital/surround/VM  (problème dans le format xmltv actuel : il ne peut y
                         avoir qu'un seul de ces choix on ne peut pas décrire une VM en dolby digital par exemple)
        - Titre original (s'il est présent)
        - Pays d'origine
        - Première diffusion/Inédit
        - Rediffusion
        - Format (4:3 ou 16:9)
        - Qualité de la vidéo (HD ou rien)
        - Critique
        - Gestion du rating CSA (Tout Public/-10/-12/-16/-18) avec URL de la signalétique quand elle existe.
        - Nombre d'étoiles.

1.9  Suppression de l'ancien rating

1.10 Suppression de l'option --verytv, le serveur n'est plus accessible au public.
          Ajout de l'option --delay

1.11 Suppression des restes du patch de tigerlol sur les chevauchements d'horaire. Ce patch ne concernait
          que le site de télépoche.

1.12 Correction de --list-channel qui ne marchait plus depuis la version 1.7 au moins et --configure
     que j'avais cassé en corrigeant les Pb d'encodage.

1.13 Correction nom de fichier de l'icone des chaine (il manquait un point devant le gif). Merci à
     Piratebab et Gilles74.
     Ajout de la possibilité d'afficher la ligne de commande (voir $DEBUG_CMD)

1.14 Inversion des positions de la saison et de l'épisode dans la description.

1.15 Correction d'un oubli dans le traitement des numéros d'épisode, si le nombre d'épisodes
     était absent, le numéro n'était pas récupéré.
     Ajout du traitement du nombre de saison.

1.16 Correction du format du star-rating.
          Modification regexp de récupération de l'année qui ne marchait plus

1.17 Si un fichier './logo-path.txt' existe, il est utilisé pour déterminer
     le chemin vers les logos des chaines lorsqu'on utilise l'option --configure.
     La version fournie est une version corrigée de lookup_tv_grab_fr_telerama.tx,
     il pointe donc vers les logos de lyngsat. Il utilise la même syntaxe mais le
     champ chid n'est pas utilisé. De cette façon le fichier de conf et le fichier
     xml généré pointe directement vers les bons logos.

1.18 Correction de quelques variables réguilère l'année et le réalisateur

1.19 Correction d'un bug dans le cas ou un $ est mis à la fin du titre ou dans d'autre champs.

1.20 Ajout de 2 options pour filtrer les programmes cryptés de Canal+ et Paris Première.

1.21 Le CSA ayant supprimé de son site les pictogrammes de rating dans un format exploitable,
     remplacement des URL par celle de Wikimedia Commons.
     Ajout initialisation oubliée de la variable $crypted.
     Traitement des réalisateurs multiples (comme pour les acteurs)
     Correction détection de sous-champ "Stéréo"
     Correction récupération du sous-champs "Durée" : il n'était plus reconnu et la
        gestion de l'unité n'était pas faite.
     Suppression variable $showview qui n'était plus utilisé.
     Le format des pages récupérées de Télérama a légérement changé :
        Ajout du sous-champ "Rediffusion :" suivi de la date de la prochaine redif. (n'est pas
           pris en compte par XMLTV, mais pollue le sous-champ "Rediffusion" (sans les ':')

1.22 L'api verytv utilisée n'es plus fonctionnelle, adaptation a une nouvelle api
     Il reste des problème d'encodage à régler

1.23 Essaie encore une fois en cas d'erreur http. après skip la chaine

1.24 Corrections de bug au décodage du json

1.25 Bug fixes

1.26 Encodage utf8 correcte et correction d'un bug pour le flag stereo

1.27 Correction de certains champs
