I just sent a new pull request for issue #100, which is the custom include macro processor. Here's an example of how it can be used.

```ruby
require 'uri-open'

# Sample content:
#
# include::https://raw.github.com/asciidoctor/asciidoctor/master/Gemfile[]
#
class RemoteIncludeProcessor < Asciidoctor::Extensions::IncludeProcessor
  def handles? target
    target.start_with?('http://') or target.start_with?('https://')
  end

  def process target, attributes
    open(target).readlines
  end
end

Asciidoctor::Extensions.register do |document|
  include_processor RemoteIncludeProcessor
end

Asciidoctor.render_file('sample-with-include.ad', :safe => :safe, :in_place => true)
```
