# MAC OSX >= 10.9.x (Maverick or newer)
#
# Syntax:
#
# getwallpaper [subreddit [new/rising/hour/day/week/month/year/all]]
#
# By default getwallpaper will fetch images that are hot from r/wallpapers
# If the first option is used but not the second then
# an image from r/[subreddit] sorted after hot, will be fetched.
#
# Example usage:
#
# getwallpaper art new
#
# This will get newly posted images from r/art
# Otherwise:
#
# getwallpaper art hour
#
# Will get top voted images from r/art in the latest hour
