#
# REQUIRES: curl, jq, lib-gd AKA gd-devel (or full PHP-gd?), fly (command-line gd processor)
#
# CONFIG:   appID: replace "demo" (resource-limited) with your own app or server ID
#           from https://na.wargaming.net/developers/applications/ (or eu/ru/asia)
#
#           TZ: set display timezone, be sure to use proper format
#
# USAGE:    ./tsBattleBanner.sh clanID [clanID2 .. clanID9]
#           Get clanID from website, ie. http://na.wargaming.net/clans/0000000000
#
# OUTPUT:   clanID.png battles for each clan
#           battles.png with battles for clans, in order specified
#
# EXAMPLE:  http://i.imgur.com/7BT8SDK.png
#
# CRON:     (crontab example that updates more often during primetime, remember timezone)
#
# TODO:     Pre-pend a clan alliance header.png
#           Get more/accurate information about landing tournaments (API methods exist)
#           For EU region use https://api.worldoftanks.eu ... sea, ru
#
#           Fix problem with string format sent to fly/gd, where extended characters
#           aren't displayed properly: jq can output utf8 or \0xaabb and gd allegedly
#           takes htmlentities? In the meantime, just don't output $province (API call
#           is still needed to check clan map)
#
#           gd/fly absolutely mangles the color palette
#           gl/fly cannot convert png emblems to jpeg/gif/truecolor
