New and Noteworthy

Command Aliases

This release adds support for command aliases.

@Command(name = "top", subcommands = {SubCommand.class},
        description = "top level command")
static class TopLevelCommand { }

@Command(name = "sub", aliases = {"s", "sb"},
        description = "I'm a subcommand")
static class SubCommand {}

new CommandLine(new TopLevelCommand()).usage(System.out);

The above would print the following usage help message:

Usage: top [COMMAND]
top level command
Commands:
  sub, s, sb   I'm a subcommand
