Rakefile

=begin
To use this build script, first install the bundler gem:

 $ gem install bundler

Then use the `bundle` command to install the dependencies into the project:

 $ rm -rf Gemfile.lock .bundle
   bundle config --local git.allow_insecure true
   bundle config --local build.nokogiri --use-system-libraries
   bundle --path=.bundle/gems

NOTE The gems are installed under the path .bundle/gems in the project.

Finally, run a named task using the `bundle exec rake` command:

 $ bundle exec rake pdf

You can get a list of tasks using the following command:

 $ bundle exec rake -T
