Update of /cvsroot/monetdb/pathfinder/compiler/Tests In directory 23jxhf1.ch3.sourceforge.com:/tmp/cvs-serv17274/Tests
Modified Files: usage.stable.out usageH.stable.out Log Message: -- Adjust help messages to the new copyright information.
Just for info for you and for who ever will take care of updating the stable output accordingly in the Nov2008 release branch and then (not) propagating it to the development trunk (most probably Sjoerd or me ...): The copyright information has obviously also been updated in the Nov2008 release branch, and the stable output for the respective tests should be updated there as well --- propagating these updates *might* then cause (probably easily resolvable) conflicts as the stable output in the development trunk has just experienced two changes: new copyright and new usage info. Note, this is neither a critique nor a major problem, but just to share information that might help to reduce / prevent inconveniences, in particular with (semi-automa[tgn]ic) propagation of chnages from the latest release branch to the development trunk. (For the future, the "ideal" procedure would (have) be(en) to first update the copyright info in the stable output of the release branch, then propagate these changes, and then update / extend the usage info in the development trunk and update the stable output there accordingly. ;-)) Stefan
