"Picocli is a one-file framework for creating Java command line applications with almost zero code. Picocli aims to be the easiest way to create rich command line applications that can run on and off the JVM.

Picocli supports a variety of command line syntax styles including POSIX, GNU, MS-DOS and more. It generates highly customizable usage help messages with ANSI colors and styles. Picocli-based applications can have command line TAB completion showing available options, option parameters and subcommands, for any level of nested subcommands. Picocli-based applications can be ahead-of-time compiled to a GraalVM native image, with extremely fast startup time and lower memory requirements, which can be distributed as a single executable file.

Picocli generates beautiful documentation for your application (HTML, PDF and Unix man pages)."
