All model collections except Word-PDF-Enhanced is built on Linux. Word-PDF-Enhanced is a windows scripting tutorial, and so its model collection needs rebuilding on a Windows machine, as does testing it. Unfortunately, the old windows machine used for running diffcol overnight is set up for GS2, so I'll be rebuilding this model collection in the Single User (Usability) Lab and will commit it from here. I'm first moving the older version that worked for GS2 out of the way, in case we need to restore it.
