Downloads 1080p wallpapers for Steam cards, using http://www.steamcardexchange.net/index.php?showcase as an index

download.rb

# INSTALLATION
# Requres ruby 1.9+, and the nokogiri gem (gem install nokogiri)
# Should work fine on Windows, Mac, Linux
# Also needs a working curl, so windows users might need to do some work there.

# USAGE
# Hit up the game you want to scrape from Steam Card Exchange, like so:
# http://www.steamcardexchange.net/index.php?gamepage-appid-440
# Then, referencing the app ID in the url, run this script:
# ruby download.rb <appid>
# It will output the download commands as it's working, and download to the working directory.

# Direct any bug reports to http://www.reddit.com/r/Steam/comments/2bglrp/psa_steam_trading_cards_are_1920x1080_wallpapers/cj572kz
