== mod_ruby

Configure mod_ruby:

  http://modruby.net/en/index.rbx/mod_ruby/install.html

But use the narf runner, instead of the default apache runner:

  <IfModule mod_ruby.c>
  RubySafeLevel 0
  # for Apache::RubyRun
  RubyRequire web/sapi/apache

  <Location / >
      Options Indexes FollowSymLinks ExecCGI
      AddHandler ruby-object cgi rb narf
      RubyHandler Web::ModNarf.instance
  </Location>
  </IfModule>

Narf will detect that mod_ruby is running and use the proper apis.
