Rake build tasks that use Asciidoctor APIs to produce common output formats for a book (or other type of publication) written in AsciiDoc.
=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
