+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 allows to
+precisely control behavior of the parser via Common Lisp restarts.")
