/**
 * Eagerly grabs all the arguments.
 *
 * <p>
 * Used with {@link Argument}, this implements a semantics where
 * non-option token causes the option parsing to terminate.
 * An example of this is ssh(1), where "ssh -p 222 abc" will treat "-p" as an option
 * to ssh but "ssh abc -p 222" is considered to have no option for ssh.
 *
 * TODO: to be moved to args4j once I confirmed that this works.
