Command-line applications: picocli-style annotations that the build turns into a parser, with help, version, subcommands and exit codes.

A class annotated CommandLine.Command is a command; its fields annotated CommandLine.Option and CommandLine.Parameters receive the arguments. The build reads the annotations, generates the code that binds them and writes main, so a command-line tool is a module with commands and nothing else, and it compiles to a native executable for Linux, macOS and Windows like any backend.

The same commands work in a backend with controllers. There the server is the serve subcommand, and the command line with no arguments starts it as before, so maintenance tasks such as a migration or an administrator account ship in the server's own binary.

Class	Description
ArgSpec	What an option and a positional parameter have in common.
CommandBinding	The code the build generates for one @Command class, through which the parser creates the command, sets its fields and runs it without reflection.
CommandLine	Parses a command line into an annotated command and runs it.
CommandLine.Command	Marks a command class.
CommandLine.IExitCodeGenerator	Implemented by a Runnable command that has an exit code to report.
CommandLine.ITypeConverter<K>	Converts the text of an argument to a type the build does not know.
CommandLine.Option	Marks a field that receives an option.
CommandLine.ParameterException	A command line that does not parse.
CommandLine.Parameters	Marks a field that receives positional parameters.
CommandLine.ParentCommand	Marks a field of a subcommand that receives its enclosing command.
CommandLine.Server	Starts the server of a backend that also has commands.
CommandLine.Spec	Marks a CommandSpec field that receives the command's own model.
CommandSpec	The model of one command: its name, help text, options, positional parameters and subcommands.
Console	What a command needs to know about the terminal it writes to.
Console.Style	The styles Console.style(String, Console.Style...) can apply.
OptionSpec	The model of one option, written by the build from an CommandLine.Option.
PositionalParamSpec	The model of one positional parameter, written by the build from a CommandLine.Parameters.
