do you have some mechanism that warns you if you try to export
uncommitted changes? I'm not sure how such a process should be designed.
I think most of the time you publish preliminary revisions and then you
will hate such a warning. On the other hand, I often do work twice when
publishing the final revision, because I forget to checkin and then the
history in the export is wrong.
