 advantage of the library is the ability to concisely define command line
 options once and then use this definition for parsing and extraction of
 command line arguments, as well as printing description of command line
 options (you get --help for free).  This way you don't need to repeat
 yourself.  Also, @command{unix-opts} doesn't depend on anything and
 precisely controls the behavior of the parser via Common Lisp restarts.")
