     1  As far as I am concerned, the code I have written for this software
     2  can be used freely for any purpose.  Any derived versions of this
     3  software must be clearly marked as such, and if the derived work is
     4  incompatible with the protocol description in the RFC file, it must be
     5  called by a name other than "ssh" or "Secure Shell".
