About Lionel Cons copyright

Hi,

After a more carefull look at the Lionel Cons copyright I am wondering
whether it is really public domain. I put an excerpt of the script
found at http://mirrors.sunsite.dk/ctan/support/texi2html/texi2html, first
top:

# @(#)texi2html	1.45 01/16/96	Written (mainly) by Lionel Cons, [email protected]

# The man page for this program is included at the end of this file and can be
# viewed using the command 'nroff -man texi2html'.
# Please read the copyright at the end of the man page.

And bottom:

.SH AUTHOR
The main author is Lionel Cons, CERN CN/DCI/UWS, [email protected].
Many other people around the net contributed to this program.

What do you think about that ? Should I try to contact Lionel Cons to 
clarify that ?
