== Rubygems
 
The easiest way to install aws/s3 is with Rubygems:
 
  % sudo gem i aws-s3 -ry
 
== Directly from svn
 
 % svn co svn://rubyforge.org/var/svn/amazon/s3/trunk aws
 
== As a Rails plugin
 
If you want to use aws/s3 with a Rails application, you can export the repository
into your plugins directory and then check it in: 
 
  % cd my-rails-application/vendor/plugins
  % svn export svn://rubyforge.org/var/svn/amazon/s3/trunk aws
  % svn add aws
  
Or you could pull it down with an svn:externals:
 
  % cd my-rails-application/vendor/plugins
  % svn propedit svn:externals .
  
Then add the following line, save and exit:
 
  aws svn://rubyforge.org/var/svn/amazon/s3/trunk
  
If you go the svn route, be sure that you have all the dependencies installed. The list of dependencies follow.
  
== Dependencies
 
AWS::S3 requires Ruby 1.8.4 or greater. 
 
It also has the following dependencies:
 
  sudo gem i xml-simple -ry
  sudo gem i builder    -ry
  sudo gem i mime-types -ry
 
=== XML parsing (xml-simple)
 
AWS::S3 depends on XmlSimple (http://xml-simple.rubyforge.org/). When installing aws/s3 with
Rubygems, this dependency will be taken care of for you. Otherwise, installation instructions are listed on the xml-simple
site.
 
If your system has the Ruby libxml bindings installed (http://libxml.rubyforge.org/) they will be used instead of REXML (which is what XmlSimple uses). For those concerned with speed and efficiency, it would behoove you to install libxml (instructions here: http://libxml.rubyforge.org/install.html) as it is considerably faster and less expensive than REXML.
 
=== XML generation (builder)
 
AWS::S3 also depends on the Builder library (http://builder.rubyforge.org/ and http://rubyforge.org/projects/builder/). This will also automatically be installed for you when using Rubygems.
 
=== Content type inference (mime-types)
 
AWS::S3 depends on the MIME::Types library (http://mime-types.rubyforge.org/) to infer the content type of an object that does not explicitly specify it. This library will automatically be installed for you when using Rubygems.
