The package description states: "This is the "classic" netcat, written by *Hobbit*. It lacks many features found in netcat-openbsd. "

Actually, the only feature I was using in the Hobbit version, the "-c" functionality, is not present in any form in the netcat-openbsd (from the man page at least).

I suggest to erase that last sentence, it might lead into thinking that netcat-openbsd has all the functionalities and more.  You could also state that "they do not share the same features".
