title: Is command pattern more than adapter?
body: <p>According to the GoF Command Pattern UML it seems to me like <em>ConcreteCommand</em> just adapts <em>Reciever</em> to common <em>Command</em> (which could be) interface. I am probably hit by <a href="http://en.wikipedia.org/wiki/Golden_hammer" rel="nofollow noreferrer">golden hammer</a>, so please explain where is the difference or what did I get wrong.</p>
