Hi folks,
It's that time of the year again when the copyright years for Sage
need to be updated to reflect the new year. The copyright years should
now span 2005--2010. The Sage wiki contains a page [1] that lists file
you need to edit in order to update the copyright years. See ticket
#7933 [2] for patches to update the copyright years in various places,
including the README.txt file and the standard documentation.

Is this really necessary?
Is it updated because you believe it is legally necessary to do so, or because
it looks better?
I'm not a lawyer, nor do I live in the USA, but at least in the UK, if you write
something you automatically get copyright, though it does no harm to make a
specific statement.
Does putting
Copyright 2005-2009 mean that the copyright has expired on the first of January
2010 ?
If README.txt has not otherwise changed, if it is believed that the copyright
needs updating on README.txt, does it not on every bit of source code? If so,
that would be huge undertaking and a huge waste of time.
If so, it might be better to just put Copyright 2010. Then if no changes are
made in 2010, there is no need to bother updating it again.
http://www.copyright.cornell.edu/resources/publicdomain.cfm
says of things published after 2002 that the copyright expires. "70 years after
the death of author. If a work of corporate authorship, 95 years from
publication or 120 years from creation, whichever expires first" Quite what
"published" means in this context is not entirely clear.
