This fixes the problems with misleading "last update" dates that only reflect the change in a single rarely-changed file. Note that hrs had reservations about doing this in the Makefile rather than with a stylesheet. However, not all our source files are XML. For now, this change works, and can be replaced by a more elegant solution later. We should also consider checking dates on other files that affect the content or appearance of documents, like images. Submitted by: grembo END
