Here is how you can convert asciidoc
text using Groovy script:
// filename: RunAsciidoc.groovy
@Grab('org.asciidoctor:asciidoctor-java-integration:0.1.3')
import org.asciidoctor.*
def asciidoctor = Asciidoctor.Factory.create()
def output = asciidoctor.renderFile(new File(args[0]), [:])
println(output);
Now you may run it
groovy RunAsciidoc.groovy myarticle.txt
