+=Paperclip
+
+Paperclip is intended as an easy file attachment library for ActiveRecord. The
+intent behind it was to keep setup as easy as possible and to treat files as
+much like other attributes as possible. This means they aren't saved to their
+final locations on disk, nor are they deleted if set to nil, until
+ActiveRecord::Base#save is called. It manages validations based on size and
+presence, if required. It can transform its assigned image into thumbnails if
+needed, and the prerequisites are as simple as installing ImageMagick (which,
+for most modern Unix-based systems, is as easy as installing the right
+packages). Attached files are saved to the filesystem and referenced in the
+browser by an easily understandable specification, which has sensible and
+useful defaults.
+
+See the documentation for +has_attached_file+ in Paperclip::ClassMethods for
+more detailed options.
+
+==Quick Start
+
+In your model:
+
+  class User < ActiveRecord::Base
+    has_attached_file :avatar, :styles => { :medium => "300x300>", :thumb => "100x100>" }
+  end
+
+In your migrations:
+
+  class AddAvatarColumnsToUser < ActiveRecord::Migration
+    def self.up
+      add_column :users, :avatar_file_name,    :string
+      add_column :users, :avatar_content_type, :string
+      add_column :users, :avatar_file_size,    :integer
+      add_column :users, :avatar_updated_at,   :datetime
+    end
+
+    def self.down
+      remove_column :users, :avatar_file_name
+      remove_column :users, :avatar_content_type
+      remove_column :users, :avatar_file_size
+      remove_column :users, :avatar_updated_at
+    end
+  end
+
+In your edit and new views:
+
+  <% form_for :user, @user, :url => user_path, :html => { :multipart => true } do |form| %>
+    <%= form.file_field :avatar %>
+  <% end %>
+
+In your controller:
+
+  def create
+    @user = User.create( params[:user] )
+  end
+
+In your show view:
+
+  <%= image_tag @user.avatar.url %>
+  <%= image_tag @user.avatar.url(:medium) %>
+  <%= image_tag @user.avatar.url(:thumb) %>
+
+==Usage
+
+The basics of paperclip are quite simple: Declare that your model has an
+attachment with the has_attached_file method, and give it a name. Paperclip
+will wrap up up to four attributes (all prefixed with that attachment's name,
+so you can have multiple attachments per model if you wish) and give the a
+friendly front end. The attributes are <attachment>_file_name,
+<attachment>_file_size, <attachment>_content_type, and <attachment>_updated_at.
+Only <attachment>_file_name is required for paperclip to operate. More
+information about the options to has_attached_file is available in the
+documentation of Paperclip::ClassMethods.
+
+Attachments can be validated with Paperclip's validation methods,
+validates_attachment_presence, validates_attachment_content_type, and
+validates_attachment_size.
+
+==Storage
+
+The files that are assigned as attachments are, by default, placed in the
+directory specified by the :path option to has_attached_file. By default, this
+location is
+":rails_root/public/system/:attachment/:id/:style/:basename.:extension". This
+location was chosen because on standard Capistrano deployments, the
+public/system directory is symlinked to the app's shared directory, meaning it
+will survive between deployments. For example, using that :path, you may have a
+file at
+
+  /data/myapp/releases/20081229172410/public/system/avatars/13/small/my_pic.png
+
+NOTE: This is a change from previous versions of Paperclip, but is overall a
+safer choice for the defaul file store.
+
+You may also choose to store your files using Amazon's S3 service. You can find
+more information about S3 storage at the description for
+Paperclip::Storage::S3.
+
+Files on the local filesystem (and in the Rails app's public directory) will be
+available to the internet at large. If you require access control, it's
+possible to place your files in a different location. You will need to change
+both the :path and :url options in order to make sure the files are unavailable
+to the public. Both :path and :url allow the same set of interpolated
+variables.
+
+==Post Processing
+
+Paperclip supports an extendible selection of post-processors. When you define
+a set of styles for an attachment, by default it is expected that those
+"styles" are actually "thumbnails". However, you can do more than just
+thumbnail images. By defining a subclass of Paperclip::Processor, you can
+perform any processing you want on the files that are attached. Any file in
+your Rails app's lib/paperclip_processors directory is automatically loaded by
+paperclip, allowing you to easily define custom processors. You can specify a
+processor with the :processors option to has_attached_file:
+
+  has_attached_file :scan, :styles => { :text => { :quality => :better } },
+                           :processors => [:ocr]
+
+This would load the hypothetical class Paperclip::Ocr, which would have the
+hash "{ :quality => :better }" passed to it along with the uploaded file. For
+more information about defining processors, see Paperclip::Processor.
+
+The default processor is Paperclip::Thumbnail. For backwards compatability
+reasons, you can pass a single geometry string or an array containing a
+geometry and a format, which the file will be converted to, like so:
+
+  has_attached_file :avatar, :styles => { :thumb => ["32x32#", :png] }
+
+This will convert the "thumb" style to a 32x32 square in png format, regardless
+of what was uploaded. If the format is not specified, it is kept the same (i.e.
+jpgs will remain jpgs).
+
+Multiple processors can be specified, and they will be invoked in the order
+they are defined in the :processors array. Each successive processor will
+be given the result of the previous processor's execution. All processors will
+receive the same parameters, which are what you define in the :styles hash.
+For example, assuming we had this definition:
+
+  has_attached_file :scan, :styles => { :text => { :quality => :better } },
+                           :processors => [:rotator, :ocr]
+
+then both the :rotator processor and the :ocr processor would receive the 
+options "{ :quality => :better }". This parameter may not mean anything to one
+or more or the processors, and they are free to ignore it.
+
+==Events
+
+Before and after the Post Processing step, Paperclip calls back to the model
+with a few callbacks, allowing the model to change or cancel the processing
+step. The callbacks are "before_post_process" and "after_post_process" (which
+are called before and after the processing of each attachment), and the
+attachment-specific "before_<attachment>_post_process" and
+"after_<attachment>_post_process". The callbacks are intended to be as close to
+normal ActiveRecord callbacks as possible, so if you return false (specifically
+- returning nil is not the same) in a before_ filter, the post processing step
+will halt. Returning false in an after_ filter will not halt anything, but you
+can access the model and the attachment if necessary.
+
+NOTE: Post processing will not even *start* if the attachment is not valid
+according to the validations. Your callbacks (and processors) will only be
+called with valid attachments.
+
+==Contributing
+
+If you'd like to contribute a feature or bugfix: Thanks! To make sure your
+fix/feature has a high chance of being included, please read the following
+guidelines:
+
+1. Ask on the mailing list, or post a ticket in Lighthouse.
+2. Make sure there are tests! We will not accept any patch that is not tested.
+   It's a rare time when explicit tests aren't needed. If you have questions 
+   about writing tests for paperclip, please ask the mailing list.

+    #   also adds the "#" option (e.g. "50x50#"), which will resize the image to fit maximally 
+    #   inside the dimensions and then crop the rest off (weighted at the center). The 
+    #   default value is to generate no thumbnails.
+    # * +default_style+: The thumbnail style that will be used by default URLs.

+    #   of thumbnail being generated. You can also specify :all as a key, which will apply
+    #   to all of the thumbnails being generated. If you specify options for the :original,
+    #   it would be best if you did not specify destructive options, as the intent of keeping
+    #   the original around is to regenerate all the thumbnails when requirements change.

+    # Amazon's S3 file hosting service is a scalable, easy place to store files for
+    # distribution. You can find out more about it at http://aws.amazon.com/s3
+    # There are a few S3-specific options for has_attached_file:
+    # * +s3_credentials+: Takes a path, a File, or a Hash. The path (or File) must point
+    #   to a YAML file containing the +access_key_id+ and +secret_access_key+ that Amazon
+    #   gives you. You can 'environment-space' this just like you do to your
+    #   database.yml file, so different environments can use different accounts:
+    #     development:
+    #       access_key_id: 123...
+    #       secret_access_key: 123... 
+    #     test:
+    #       access_key_id: abc...
+    #       secret_access_key: abc... 
+    #     production:
+    #       access_key_id: 456...
+    #       secret_access_key: 456... 
+    #   This is not required, however, and the file may simply look like this:
+    #     access_key_id: 456...
+    #     secret_access_key: 456... 
+    #   In which case, those access keys will be used in all environments. You can also
+    #   put your bucket name in this file, instead of adding it to the code directly.
+    #   This is useful when you want the same account but a different bucket for 
+    #   development versus production.
+    # * +s3_permissions+: This is a String that should be one of the "canned" access
+    #   policies that S3 provides (more information can be found here:
+    #   http://docs.amazonwebservices.com/AmazonS3/2006-03-01/RESTAccessPolicy.html#RESTCannedAccessPolicies)
+    #   The default for Paperclip is "public-read".
+    # * +s3_protocol+: The protocol for the URLs generated to your S3 assets. Can be either 
+    #   'http' or 'https'. Defaults to 'http' when your :s3_permissions are 'public-read' (the
+    #   default), and 'https' when your :s3_permissions are anything else.
+    # * +s3_headers+: A hash of headers such as {'Expires' => 1.year.from_now.httpdate}
+    # * +bucket+: This is the name of the S3 bucket that will store your files. Remember
+    #   that the bucket must be unique across all of Amazon S3. If the bucket does not exist
+    #   Paperclip will attempt to create it. The bucket name will not be interpolated.
+    #   You can define the bucket as a Proc if you want to determine it's name at runtime.
+    #   Paperclip will call that Proc with attachment as the only argument.
+    # * +s3_host_alias+: The fully-qualified domain name (FQDN) that is the alias to the
+    #   S3 domain of your bucket. Used with the :s3_alias_url url interpolation. See the
+    #   link in the +url+ entry for more information about S3 domains and buckets.
+    # * +url+: There are three options for the S3 url. You can choose to have the bucket's name
+    #   placed domain-style (bucket.s3.amazonaws.com) or path-style (s3.amazonaws.com/bucket).
+    #   Lastly, you can specify a CNAME (which requires the CNAME to be specified as
+    #   :s3_alias_url. You can read more about CNAMEs and S3 at 
+    #   http://docs.amazonwebservices.com/AmazonS3/latest/index.html?VirtualHosting.html
+    #   Normally, this won't matter in the slightest and you can leave the default (which is
+    #   path-style, or :s3_path_url). But in some cases paths don't work and you need to use
+    #   the domain-style (:s3_domain_url). Anything else here will be treated like path-style.
+    #   NOTE: If you use a CNAME for use with CloudFront, you can NOT specify https as your
+    #   :s3_protocol; This is *not supported* by S3/CloudFront. Finally, when using the host
+    #   alias, the :bucket parameter is ignored, as the hostname is used as the bucket name
+    #   by S3.
+    # * +path+: This is the key under the bucket in which the file will be stored. The
+    #   URL will be constructed from the bucket and the path. This is what you will want
+    #   to interpolate. Keys should be unique, like filenames, and despite the fact that
+    #   S3 (strictly speaking) does not support directories, you can still use a / to
+    #   separate parts of your file name.
