Capsule is an open-source packaging and deployment tool for JVM applications. A capsule is a single executable JAR that contains everything your application needs to run either in the form of embedded files or as declarative metadata. It can contain your JAR artifacts, your dependencies and resources, native libraries, the required JRE version, the JVM flags required to run the application, Java or native agents and more. In short, a capsule is a self-contained JAR that knows everything there is to know about how to run your application the way it's meant to run.
Command line args have changed slightly since this point; "find jar" instead of "--find --level=jar"
