Currently the main catalyst script file reports Gentoo's copyright from 1999-2005. Since the copyright has been updated for 2006, the script file should be changed from "1999-2005" to "1999-2006". Also, the individual script files (eg stage[123]-chroot.sh, builder.py) have the copyright of 1999-2005 in the header/comments. Again, since the copyright has been updated, these should also be changed.
