#   Non-essential
# + Finicky
# ---------------
# Not in toolkit


















# ActiveResource wants:
# [record1,record2,record3]

# Many APIs deliver:
# {:metadata => some_info, :page_number => 3, :total_pages =>7,
#  :records => [record1,record2,record3]}











# More low level, at the top for some reason

# More high level







RestClient # 1.4.2, last updated March 13, 2010

books = RestClient.get 'http://bookstore.example.com/books.xml'
books.body # Raw XML



# Multipart!
RestClient.post '/data', :myfile => File.new("/path/to/image.jpg")
