// This example demonstrates creating a PDF using common options and saving it
// to a place on the filesystem.
//
// It is created asynchronously, which means DocRaptor will render it for up to
// 10 minutes. This is useful when creating many documents in parallel, or very
// large documents with lots of assets.
//
// DocRaptor supports many CSS and API options for output customization. Visit
// https://docraptor.com/documentation/ for full details.
//
// You can run this example with: ./script/run_java_file examples/Async.java
