ODE 2.1.1 documentation

It looks like I have the ODE source (with doc sources) for 2.3.4 and 2.3.6 2.3.4 is from 1997, 2.3.6 from 1998. Is that old enough for you? IANAL, but the copyright doc looks good Copyright (c), 1990, 1991, 1992, 1993, 1994, 1995, 1996, 1997, 1998 The Open Group Research Institute ("TOG RI"), Permission is hereby granted to use, copy, modify and freely distribute the software in these files and their documentation for any purpose without fee, provided that the above copyright notice appears in all copies and that both the copyright notice and this permission notice appear in supporting documentation.
