No. It means that the software was developed between 2005 and 2009, and that the copyright term should extend from that period according to the relevant country's laws. > 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. Well, it could be automated with a sed script, but that's not necessary. Only files that have been modified in 2010 should have a 2010 copyright notice. > If so, it might be better to just put Copyright 2010.
