--- Comment #14 from Jerry DeLisle <jvdelisle at gcc dot gnu.org> 2011-07-23 15:26:09 UTC --- Several years ago, I sketched out a "flow" chart for all of namelist so I could walk the logic and see what to do. I think we need to do this again and maybe post it to the wiki. (unfortunately I do not have that sketch)
