107 NB that NO VERSIONS of this file have been released, and I do not
108 intend to publish this version. If you get this file from a
109 work-in-progress or abandoned branch, old old version, in a version
110 control system (eg CVS or git) I definitely do not intend the licence
111 exceptions in it to apply - these were all drafts, as you should know
112 if you know what retrieving work in progress, old or abandoned
113 versions or branches means !
