[mod.legal] public domain notation

drears@ARDEC.ARPA ("1LT Dennis G. Rears", FSAC) (10/10/86)

   I see in a lot of software a statement to the effect:


    This software is in the public domain, however this software can
not be used for personal gain or corporate gain and must contain the
note this was developed by xxx.

It seems to me that since it is in the public domain. Anyone can do
whatever they want with it.  Of course you should include the note
as a courtesy.  Any comments?
