3 * scp - secure remote copy. This is basically patched BSD rcp which-
4 * uses ssh to do the data transfer (instead of using rcmd).-
5 *-
6 * NOTE: This version should NOT be suid root. (This uses ssh to-
7 * do the transfer and ssh has the necessary privileges.)-

12 * can be used freely for any purpose. Any derived versions of this-
13 * software must be clearly marked as such, and if the derived work is-
14 * incompatible with the protocol description in the RFC file, it must be-
15 * called by a name other than "ssh" or "Secure Shell".-
