As someone new to ROS I find it very frustrating to have the pre-catkin documentation in the Wiki. I would suggest you quickly move the pre-catkin material to a separate Wiki for those still using those versions. Then begin a rolling update system for new releases. You might keep three release in the main Wiki while rolling previous releases into a historical Wiki separate from the pre-catkin Wiki. That might entail too much work, I realize. Maybe a diff/merge through a version control system would work? I suggest that anyone working with versions 3 years out of date probably can figure out the documentation even if it is not perfect. - 73 - *Rud Merriam K5RUD * /Mystic Lake Software /
